What Type of Sunglasses Are Best For People With Low Vision?

What Type of Sunglasses Are Best For People With Low Vision 640×350

While everyone should wear sunglasses that block 100% of the sun’s harmful UV rays, those with low vision greatly benefit from the sunglasses’ decreased glare and improved contrast and clarity.

Below are a few things to consider when selecting glasses if you have low vision.

Protection

The first and most crucial feature to look for in sunglasses are lenses that provide 100% UV-A and UV-B protection. Your eyelids, cornea, lens, and certain sections of the retina can all be damaged by ultraviolet light.

Don’t buy sunglasses if the label doesn’t say 100% UV Protection against both UVA and UVB’ or 100% protection against UV 400. Consider purchasing wrap-around or tight-fitting sunglasses that don’t allow UV light to reach your eyes from the sides or the top of the glasses.

Visibility

Many people often believe that darker lenses equal better protection. In fact, darker lenses don’t necessarily provide better protection and may even reduce visibility, especially for people with eye conditions like glaucoma. Before purchasing sunglasses, discuss the optimal lens darkness with your low-vision eye doctor. Then try a variety of lens shades in the office to see which ones provide the most visibility and comfort.

Glare

Glare sensitivity is a symptom of macular degeneration and many other eye conditions. Even when sitting in the shade, the sun can reflect off the water, the road, a car’s hood and other surfaces, creating a harsh glare. Polarized sunglass lenses decrease the glare reflected off these and other surfaces. This results in increased comfort, improved clarity and reduced eye fatigue.

Clarity

Since macular degeneration reduces one’s sharp vision, wearing sunglasses with high-quality lenses is critical. The clarity of the lens is determined by the quality of the lens material. When trying on the lenses, ask the staff to get you the clearest sunglass lenses they have.

Enhanced Contrast

People with low vision struggle to distinguish contrast. Fortunately, certain tinted lenses provide improved contrast. These include orange and yellow lenses.

So before you select your new pair of sunglasses, make sure to wear them outside and see whether they provide optical clarity, decreased glare, and improved contrast.

If you or a loved one has low vision, contact Low Vision Center At Rancho Mirage Eye Care Optometry to discuss which sunglasses are right for you.

Our practice serves patients from Palm Springs, Palm Desert, La Quinta, and Indio, California and surrounding communities.

Low Vision and Visual Hallucinations

Illustrating Visual HallucinationsAny eye condition that results in vision loss can lead a person to experience visual hallucinations. Wet age-related macular degeneration (AMD) is no exception. Wet AMD is caused by new blood vessels leaking fluid into the retina, resulting in permanent macular damage and vision loss.

Visual hallucinations caused by vision loss are also known as Charles Bonnet syndrome (CBS) — an infrequent yet disabling symptom of wet AMD. These hallucinations, unrelated to mental illness, can be highly disconcerting and even frightening when they first appear.

The hallucinations have no known cure or single treatment. However, by understanding what causes them, you’ll be able to reduce your anxiety when they occur and establish techniques to get through them with minimal discomfort.

Contact Low Vision Center At Rancho Mirage Eye Care Optometry if you’re experiencing vision loss and associated hallucinations. We can help you manage your symptoms and help you maximize your remaining vision.

What is Charles Bonnet Syndrome?

It is estimated that 50-60% of people suffering from severe vision loss experience visual hallucinations. Patterns, as well as more complex pictures such as people, animals, flowers, and buildings, can appear during these hallucinations.

This occurs because, in patients with severe eye diseases, such as age-related macular degeneration, glaucoma, or diabetic retinopathy, the eyes no longer send visual signals to the brain as before. Without them, the brain fills the void by recalling images from memory, resulting in visual hallucinations.

CBS was named after Charles Bonnet, an 18th-century Swiss scientist who first identified this condition in his grandfather and then developed it himself.

What Do Visual Hallucinations Look Like?

CBS hallucinations may appear as simple as flashes of light, colors or shapes.

Others may experience more complex structures, such as geometrical grids and lattices.

Landscaped gardens, animals, people, and a procession of costumed characters wearing hats have also been reported by CBS patients.

Some people find their hallucinations enjoyable, while others find them to be an unwelcome inconvenience, especially if they temporarily obstruct vision.

When Do Visual Hallucinations Occur?

CBS hallucinations come and go without warning, typically spanning over months or years, with no apparent reason and no connection to cognitive or psychiatric disease.

The syndrome’s prevalence in patients with visual impairment varies from 10% to 15%, but can also affect patients with other eye conditions or diseases, including glaucoma and stroke.

While CBS is more frequent in those over the age of 80, it can affect anyone at any age. In fact, people can also experience visual hallucinations even if they just have minor vision loss or small blind spots.

What Causes CBS?

Exactly what causes visual hallucinations is unknown, but researchers believe that the interruption or destruction of nerve cells leads to the loss of signals from the eye to the brain. MRIs show that these visual signals ordinarily inhibit some nerve activity in the brain. So when the signals between the eye and brain are missing, there is more spontaneous nerve activity, which is perceived as hallucinations.

How to Manage Visual Hallucinations

Eye movements appear to reduce the severity and duration of hallucinations. Even if individuals have limited remaining vision, eye movements engage visual areas of the brain in people with macular degeneration. Certain types of hallucinations, notably patterns and colors, may be stopped by these motions.

[Eye_doctors] recommend patients consciously move their eyes when experiencing a hallucination.

Try the following exercise:

    • Imagine two locations on a wall in front of you that are about 3 feet apart from each other. For 15–30 seconds, stand 3.5 feet away and glance from one place to the other once every second or faster. When looking left and right, don’t move your head and keep your eyes open.
    • Repeat the exercise if your hallucinations are still there.

    The technique is unlikely to work if the hallucinations have not stopped after four or five attempts. However, you might want to try again later.

    Other ways to stop a hallucination:

    • Look away from the image towards an object on the side of your vision or shut your eyes
    • Turn on the lights in the room or, if you’re in a brightly lit room, go somewhere darker.
    • Get up and engage in physical activity.

    If you have wet AMD and are experiencing visual hallucinations, contact Low Vision Center At Rancho Mirage Eye Care Optometry. We can help.

    Our practice serves patients from Palm Springs, Palm Desert, La Quinta, and Indio, California and surrounding communities.

     

    Frequently Asked Questions with Dr. Greg Evans

    Q: Are there risk factors for CBS?

    • A: While people of any age can be affected by Charles Bonnet hallucinations, it tends to occur later in life and usually after a sudden deterioration of vision.

    Q: Can other conditions cause visual hallucinations?

    • A: Other disorders that might cause visual hallucinations include psychiatric diseases and neurologic conditions like Parkinson’s disease and Alzheimer’s disease. Visual hallucinations can also be caused by a variety of prescription and illegal substances, as well as withdrawal from drugs or alcohol. Speak with your eye doctor if you are experiencing hallucinations.

    Coping with Low Vision? 5 Ways to Make Your Home Safer

    Man with Low Vision on SofaIf you’ve been diagnosed with low vision, you may be worried about banging into the furniture or falling down the stairs. These simple modifications will help you stay safe at home, even with limited vision.

    What is Low Vision?

    Low Vision refers to significant visual impairment that can’t be fully corrected with conventional glasses, contact lenses, medication or eye surgery. The condition impacts nearly 250 million people worldwide, and 7% of all people over age 65. The most common symptoms of low vision are:

    • Blurred vision
    • Blind spots
    • Tunnel vision
    • Poor night vision

    The condition is often the result of eye diseases such as glaucoma, macular degeneration and diabetic retinopathy. Low vision can also result from congenital conditions, eye injuries and stroke.

    Although vision loss can’t be reversed, adjustments in your home can help you remain active, independent and safe.

    5 Ways Low Vision Patients Can Stay Safe at Home

    Get [Organized]

    It’s time to organize your home. Remove things you don’t need and anything that can impede your mobility around the house.

    • Get rid of loose area rugs
    • Make sure your carpet is completely fastened to the floor
    • Use zip ties and other fasteners to keep long cords out of the way
    • Confine small stools or tiny tables to areas where you don’t walk

    Become a master [organizer]. Be sure to put kitchen utensils, tools and other items in separate drawers and containers. Organize clothing in your closet by color, coats from light to heavy and shoes by season.

    Label Everything

    Having a place for everything is key. Once you’ve decided where everything should be, the next step is labeling your belongings. Use large letters and dark ink against light-colored paper, or brightly colored labels to differentiate between items.

    Go for Contrast

    Using contrasting colors is an easy way to make items stand out. If your couch is dark, place light-colored pillows at each end so you can see where to sit. Place fluorescent strips on dark stairs or dark strips on light stairs so you can step safely.

    Lighten Up

    Lighting your home properly can make a huge difference in your ability to see things and live safely, especially in places like the kitchen. You can add more brightness by:

    • Installing lighting in closets and under cabinets
    • Choosing bulbs with higher wattage
    • Using lights during the day to reduce glare
    • Try different types of lighting to see what helps you maximize your vision

    Use Low Vision Aids and Devices

    Your Low Vision Optometrist may prescribe low vision glasses and devices to enable you to see better and by helping you maximize your remaining vision. These include:

    • Telescopes – hand-held, spectacle-mounted and clip-on
    • Magnifiers – hand-held and standing
    • Non-optical visual aids – devices that increase light and enhance contrast
    • Computer-based aids – use software and large screens
    • Mobile phone applications – allow easier communication

    Discuss this with your eye doctor to see which types of visual aids are best for you. Many people with low vision use several types of visual aids for specific activities — for instance, magnifiers for reading and additional lighting for preparing food.

    Make the most of the internet with voice search features. This is particularly helpful if you quickly need emergency numbers or need to locate other information.

    Smart technology has revolutionized life for people with low vision. Voice-activated features let you turn lights on and off, open and close your garage doors and contact emergency services immediately.

    Frequently Asked Questions with Dr. Greg Evans

     

    Q: What is the difference between low vision and legal blindness?

    • A: Legal blindness is a legal term that refers to corrected visual acuity of 20/200 or less in the better eye or a visual field of 20 degrees or less. A person with low vision is someone who has permanent vision loss and cannot do those tasks they wish to do.

    Q: Who is at risk for low vision?

    • A: People with the highest risk for low vision are typically over 65 and have a family history of AMD. For some reason, AMD affects women more than me, and Caucasians/Asians more than African Americans. Similarly, diabetic retinopathy and glaucoma also cause vision loss and tend to be more prevalent among African Americans.

    Dating With Low Vision

    elderly couple dating with low visionFor people with low vision, the logistics of dating can sometimes feel overwhelming. Your visual needs can change the dynamics of how the date goes, where you feel comfortable going, and what you feel comfortable doing. For many, it’s enough to give up on the idea altogether. But don’t throw up your hands in frustration just yet!

    At Low Vision Center At Rancho Mirage Eye Care Optometry in Rancho Mirage, we want to assure you that with a little bit of planning, dating can be a great experience, even with low vision.

    Here are some of our top tips on how to make it work:

    1. Play an active role in setting up the date.

    It’s not always easy figuring out where to go on a date. This is especially true when you have special visual considerations that factor into your options. Make sure to take an active role in choosing a place and activity you feel comfortable with.

    If you’re going out to dinner, consider restaurants in your area that offer good lighting, menus in large print or braille, and which may have special experience and/or accommodations for people with vision difficulties.

    If you and your date would like to enjoy a movie together, look for theaters that offer audio descriptions so that you can enjoy the movie too.

    2. Pick a place you can reach by public transit or within walking distance.

    It’s always best to choose a place you can get to on your own. This is especially important if you’re just meeting someone for the first time and you’re not sure how the date will go. Choosing a place that you can easily walk to or is serviced by public transportation will give you the freedom to leave when you want to.

    3. Be prepared to have a conversation about your visual impairment – if you want to.

    There are always conversations to be had when you’re meeting someone for the first time. The question is, when do you bring them up and how much do you say at first? Having a conversation about your visual impairment is no different.

    Your low vision may have already influenced your choice of date spot and the activities you’ve planned, so don’t be surprised if your date asks questions.

    Whether you want to discuss your low vision on a first date is entirely up to you. Do what feels comfortable.

    4. Don’t forget about traditional places to meet people.

    Your whole life shouldn’t be defined by your vision disability, and your dating life is no exception. If you enjoy reading, join a book club. Love to exercise? Join a gym or even a cycling club – tandem biking is fun. If you’re religious, attend services at your local church, synagogue, mosque. If you enjoy giving back to your community, find local opportunities to volunteer. These are great places to find like-minded people for friendship and, with a little luck, romance. Shared interests and values are a great way to build a meaningful relationship.

    5. Be yourself.

    In the end, the biggest advice anyone can give is the oldest in the book. Just be yourself!

    Our practice serves patients from Palm Springs, Palm Desert, La Quinta, and Indio, California and surrounding communities.

     

    Frequently Asked Questions with Dr. Greg Evans

    Q: What is low vision?

    Low vision is defined as fully corrected vision (with glasses/contacts/surgery) that is still insufficient to do what you want to do.

    There are many causes of low vision, including glaucoma, cataracts and macular degeneration, stroke and eye injuries. Patients with these conditions need two eye doctors. The medical eye doctor treats the medical condition. Low vision optometrists prescribe low vision glasses and aids to help with the vision loss condition. Low vision aids, such as telescope and microscope glasses, E-Scoop glasses, prism glasses and magnifiers make the most of the remaining vision and help maintain independence and quality of life.

    Q: What is a low vision exam?

    A: A low vision exam evaluates your level of vision, as well as the tasks you wish to do and can no longer engage in due to your limited vision. The low vision exam goes above and beyond the usual comprehensive eye exam performed by your eye doctor and concentrates on your visual needs.

    Your eye doctor will ask you questions about your family history, your eye health and your general health. You’ll also be asked if you have difficulty with vision for daily tasks such as driving, reading or pouring yourself a cup of coffee.

    All of this information will allow your eye doctor to accurately assess your level of vision loss and how it is affecting your daily life. With this information, they will be able to advise you on the proper steps you can take, and low vision glasses and aids you can use to maintain your independence and make the most of your remaining vision.

      4 Signs You Have a Visual Contrast Sensitivity Problem

      elderly couple with low vision glasses sitting outside

      Contrast sensitivity allows you to tell the difference between the foreground and background. It’s a crucial aspect of your visual function, particularly in low-light situations.

      Common scenarios which require contract sensitivity include driving at night, in the rain or fog, or reading a newspaper, where the writing is printed on a gray background. The inability to distinguish objects clearly is not simply an inconvenience; it can lead to car accidents or falls that may cause injury.

      Reduced visual contrast sensitivity is often a symptom of a more serious eye condition, such as cataracts, glaucoma or macular degeneration. This is why it’s important—especially for those over 50—to undergo an annual eye exam. Your low vision eye doctor will measure how well you can tell the difference between light and dark by using a specific chart where the characters fade from black to gray gradually. If symptoms are present, your Low Vision Center At Rancho Mirage Eye Care Optometry low vision eye doctor will provide you with treatment options, such as visual aids and devices to help you improve contrast sensitivity.

       

      4 Signs of Visual Contrast Sensitivity Problems

      The onset of this condition is often gradual and people may not notice a change in vision as it progresses. The following are common signs of reduced visual contrast sensitivity:

      1. Reading Difficulties

      People with reduced visual contrast sensitivity may be able to read normally if the letters are dark and the background is light, or vice-versa. However, if the letters and the background are of a similar color or level of brightness or faintness, people with reduced visual contrast sensitivity may struggle to read the text.

      2. Problems Differentiating Between Objects

      As with reading, poor visual contrast sensitivity doesn’t affect the ability to see objects, except when these objects are the same or similar colors as their surroundings. For instance, it may be difficult to locate black gloves in a black purse or see a white bird flying in a cloudy sky.

      3. Tripping Over Curbs or Steps

      People with contrast sensitivity difficulties may start realizing they have a problem if they keep tripping over curbs or steps because they don’t see them clearly. Steps and curbs are often the same shade as the surrounding surface and may not be visible to people with this vision problem.

      4. Driving in Certain Conditions

      People with reduced visual contrast sensitivity may struggle to drive in certain conditions:

      • Low light
      • Rain
      • Glare
      • Fog

      Contrast sensitivity is essential for driving because it allows the driver to see road signs, pedestrians and road curves, and to distinguish between the road and the curb.

      Tests for Visual Contrast Sensitivity

      Even people with 20/20 vision can experience a noticeable decrease in their visual acuity if they are exposed to glare or if the letters on a chart are of a similar color to the background.

      The Pelli Robson test was designed specifically to determine if a patient has difficulties with contrast sensitivity. The test is similar to the Snellen test because it features horizontal lines of letters. However, in this test, instead of shrinking in size with each descending row, the letters show less contrast, appearing in ever weaker shades of gray against a white background.

      For instance, on the top row, the letters are black and the background is white. In subsequent rows, the letters are lighter gray until the contrast against the white background is very subtle on the bottom row.

      If you have difficulty distinguishing between objects and their backgrounds or seeing road signs and steps, schedule an eye exam with Dr. Greg Evans at Low Vision Center At Rancho Mirage Eye Care Optometry today.

      Frequently Asked Questions with Dr. Greg Evans

      Q: What Causes Reduced Visual Contrast Sensitivity?

      • A: Difficulties with visual contrast sensitivity tend to be a symptom of another ocular problem. Here are some common causes of the condition:
        • Glaucoma
        • Macular degeneration
        • Severe dry eye syndrome
        • Cataracts
        • Diabetes
        • Optic neuropathies
        • Eye infections or trauma

      Q: How Can Visual Contrast Sensitivity Be Improved?

      • A: If the eye doctor identifies a problem with contrast sensitivity, the main form of treatment is to treat the underlying condition, which in most cases improves the contrast sensitivity as well. If the condition remains, the doctor can discuss treatment using specialized glasses that can enhance the quality and amount of light that enters the eye.
        • Tinted lenses filter out glare, and the yellow tint can help the patient see contrasts more clearly, especially at night
        • Anti-reflective coatings eliminate reflections from the surfaces of the eyeglasses and greatly reduce glare
        • Photochromic lenses gradually become darker as the surroundings become lighter, and vice-versa, and act as both regular glasses and sunglasses when needed
        • Polarized lenses reduce reflected glare, such as off water, snow and windshields.

        Intraocular lenses, which replace the eye’s natural lens during cataract surgery, can enhance contrast sensitivity and reduce some of the vision problems caused by cataracts.

      5 Reading Tips Following Retinal Detachment Surgery

      elderly woman reading with glassesRetinal detachment is a potentially sight-threatening condition that requires immediate attention. When the light-sensitive retina has slipped out of its position, surgery is required to reattach it. Recovery from surgery is lengthy and it may be weeks or months before vision is fully restored.

      Patients often wonder how soon they will be able to read following retinal detachment surgery. The answer will depend on the severity of the detachment and the outcome of the surgery. In some cases, additional surgery may be required.

      About Retinal Detachment Surgery

      There are three types of retinal detachment surgery:

      • Pneumatic retinopexy – injecting a gas bubble into the eye to push the retina back into place
      • Scleral buckling – placing a belt-like structure around the white of the eye
      • Vitrectomy – replacing the aqueous humor with silicone oil

      How Long Does It Take to Recover from Retinal Detachment Surgery?

      Every patient will recover from surgery at a different pace, but most patients can resume some of their regular activities between 2 and 4 weeks post-op. For some people, it can take several months.

      During this recovery period, it’s crucial to avoid doing things that require vigorous head movements. It will be a while before you will be able to:

      • Clean
      • Garden
      • Lift heavy objects
      • Engage in strenuous activities like a workout

      Reading Tips Following Retinal Surgery

      Vision in the affected eye or eyes is likely to be poor for weeks following surgery, making it difficult to read. Until the retina heals and holds its position, you may see bright spots or your vision could be blurry. However, reading or watching television won’t harm your eyes, and there is no reason not to try to read if you feel so inclined.

      The following are some tips for reading following retinal detachment surgery:

      1. Check Your Eyeglass Prescription

      When your eye surgeon feels your eye has recovered, they will recommend having an eye exam to determine whether your eyeglass prescription is still right for you. It is possible that surgery has altered your optical prescription, so having updated eyeglasses will help you see and read more clearly.

      2. Use Adequate Lighting

      The retina contains layers of nerves that are sensitive to light. You may need more light to see and read than you did before your retina detached. Add some extra lamps and use fluorescent and halogen bulbs that illuminate reading material more effectively than incandescent bulbs.

      3. Get Assistance from Screen Readers

      In the days and weeks following surgery, when you are not yet able to read from books or a computer, use a screen reader, which converts written text into auditory recordings.

      4. Find Large Print Books and Audiobooks

      Make reading easier by reading from books with large print, or bypass reading altogether by listening to audiobooks.

      5. Magnify Your Screen or Book

      A magnifying device will make letters in printed material larger and more accessible. Your low vision optometrist can recommend specific low vision glasses or devices that can enlarge text and graphics to the extent you require.

      Also, you may find it easier to read with the unaffected eye. Reading with only the good eye will not harm either eye, so do not be afraid to read that way until the reattachment heals.

      After surgery, patients want to resume their favorite activities, including reading, as quickly as possible. Your eye doctor will determine when your eyes and vision have recovered and you are ready to enjoy your daily activities based on your recovery from retinal detachment surgery. You will need some follow-up eye exams to ensure that your eyes are healing well and that your retina remains in position. To schedule an appointment, call us today.

      Our practice provides low vision management, aids and devices to patients from Palm Springs, Palm Desert, La Quinta, and Indio, California and surrounding communities.

      Frequently Asked Questions with Dr. Greg Evans

      Q: What Are the Risk Factors for Retinal Detachment?

      A: The following are risk factors for retinal detachment:

      • – A previous case of retinal detachment
      • – Cataract surgery
      • – Eye injury
      • – Severe near-sightedness (myopia)
      • – Diabetic retinopathy
      • – Posterior vitreous detachment – the vitreous humor becomes separated from the retina
      • – Retinoschisis – the retina separates into two layers

      Q: How Does an Optometrist Test for Retinal Detachment?

      • A: If an eye doctor thinks you may have retinal detachment, your eyes will be dilated so the optometrist can see the retina and the back of your eye. Eye drops will be placed into the eye to make the pupils wider. The eye doctor may press on the eyelids to check for retinal tears. In addition to the dilated eye exam, the optometrist may check your eye with ultrasound or an optical coherence tomography (OCT) examination to confirm whether the retinas are detached.

      What’s the Difference Between Low Vision and Blindness?

      Elderly couple dancing

      Low vision doesn’t mean blindness. It simply means that a portion of your vision is impaired, and you can continue to enjoy a high degree of independence thanks to low vision tools and devices.

      What Is Low Vision?

      People often confuse the terms ‘visual impairment,’ ‘low vision,’ or ‘blindness’. Below we’ll untangle that and bring some clarity to each term:

      Visual impairment is a broad term that refers to any loss of vision. The following are some of the terms used to characterize different types of vision impairment:

      • Low vision is defined as fully corrected vision that is insufficient or interferes with your ability to do the things you want to be able to do. It has nothing to do with your visual acuity, field of view or other visual functions like dark adaptation or contrast sensitivity.
      • Legally blind refers to vision that is 20/200 or less in your better eye that cannot be corrected with standard glasses or contacts, or a visual field of 20 degrees or less. Certain conditions, like glaucoma, cataracts, diabetic retinopathy, and macular degeneration can cause one to be legally blind.
      • Total blindness is defined as the complete lack of form and light perception that often results due to a genetic condition, disease, or injury.
      • Partial vision refers to the capacity to see only a portion of your visual field, or to have good central vision but poor peripheral vision. A brain tumor, brain injury, or an eye condition are the most common causes.

      Does Low Vision Mean Blindness?

      No. Vision loss that cannot be corrected with glasses, contact lenses or surgery is known as low vision. However, because some vision remains, it is not considered to be blindness. A person with low vision may have blurred vision, blind spots or have poor night vision.

      Common Types of Low Vision

      Loss of central vision

      A blur or blind spot in the center of what you’re looking at occurs from a loss of central vision. This makes it difficult to read, recognize people and identify features at a distance. A person’s side (peripheral) vision is mostly unaffected by the loss of central vision.

      As long as the person has adequate side vision, mobility is still possible.

      Loss of peripheral (side) vision

      Peripheral vision loss leaves a person with remaining central vision, allowing them to see straight ahead, read, watch TV and recognize faces. This is referred to as tunnel vision and can be caused by glaucoma, a brain tumor or injury.

      Peripheral vision loss makes it difficult to differentiate objects on one or both sides, as well as items directly above and below eye level. Mobility is often hindered by a loss of peripheral vision.

      Blurred vision

      Blurred vision causes both near and far vision to be out of focus. When blurred vision is caused by refractive error, glasses, contact lenses and sometimes surgery can clear it up. However, certain conditions may cause blurred vision that cannot be corrected, such as macular degeneration, cataracts and diabetic edema.

      Reduced contrast sensitivity

      People with poor contrast sensitivity struggle to distinguish an object from other objects having the same background color/shade. For example, a person wearing gray clothing would be difficult to see on a cloudy day. Similarly, finding a blue wallet in a blue purse can be difficult for those with reduced contrast sensitivity. Others may find driving difficult even if their “acuity” is good because visual acuity is measured on high contrast charts. The most common eye diseases that cause contrast sensitivity loss include macular degeneration and cataracts.

      Glare/light sensitivity

      There are two types of glare: discomfort glare and disability glare.

      Patients with discomfort glare tend to feel discomfort in the presence of sunlight, incandescent lights, fluorescent lights, and halogen lights, like those used in car headlights. Glare can emanate from many sources, such as reflection from water, fresh snow or white sand.

      Those with disability glare cannot function in these lighting conditions, posing a danger of being in harm’s way.

      Frequently Asked Questions with Dr. Greg Evans

      Q: What is a low vision evaluation?

      • A: A low vision evaluation includes components that are not usually part of a standard eye exam. Your vision will be evaluated to assess the nature and level of vision loss and how it’s affecting your ability to do the things you want to do. The evaluation will help determine which types of low vision glasses and devices to prescribe for improved function, safety and independence.

      Q: What causes low vision?

      • A: Traumatic brain and eye injuries, as well as congenital conditions and issues of aging and uncorrected refractive errors, are all common causes of low vision. As you age, you’re more likely to develop various eye conditions, like cataracts, glaucoma, diabetes and age-related macular degeneration. When treated early, vision loss can be prevented or limited. However, left untreated, some of these conditions can eventually lead to severe vision loss or even total blindness.

      Macular Degeneration Hasn’t Stopped Judi Dench, And It Shouldn’t Stop You Either

      Judi Dench 640×350

      You may recognize this Academy Award-winning actress from her numerous performances on TV, the stage, and the big screen. But aside from offering the world artistic masterpieces, Dame Judi Dench provides hope and inspiration to low vision patients around the globe.

      Dench has been vocal about her struggles with vision loss due to age-related macular degeneration (AMD), and shares why the progressive eye disease isn’t stopping her from accomplishing her goals.

      What is Macular Degeneration?

      Age-related macular degeneration is an eye condition that causes the gradual breakdown of the macula center of the retina, resulting in central vision loss — but does not lead to total loss of sight. So, for example, when a person with advanced AMD looks at their grandchild they may see the clothes the child is wearing, but not the child’s face.

      There are two types of AMD: wet and dry. Dry AMD is much more common than wet, affecting more than 8 out of 10 patients with the condition.

      Dry AMD is caused by slow degradation of the macula that leads to deposits of damaged retinal cells and gradual vision loss over several years. Wet AMD comprises about 20 percent of all AMD cases and is more severe than the dry type. Wet AMD occurs when new blood vessels develop underneath the retina and leak fluid, causing distorted vision and vision loss. Vision loss occurs much faster with wet AMD, resulting in permanent scarring inside the eye and severe vision loss.

      Symptoms of AMD include:

      • Blurred vision
      • Difficulty recognizing faces
      • Difficulty or inability to adjust to dim light
      • Straight lines appearing wavy or distorted
      • Requiring bright light to perform daily tasks
      • A dark spot in the center of your visual field (wet AMD)

      The onset of symptoms may be subtle and can easily go unnoticed. That’s why regular comprehensive eye exams are so crucial. The earlier the diagnosis and treatment, the better the outcome.

      Unfortunately, there aren’t yet any known cures for either version of AMD, but there are a few treatments that may help slow vision loss. Moreover, your low vision optometrist can provide you with low vision aids and devices to help you continue to live a full, independent life.

      How Judi Dench Copes With AMD

      Judi Dench has both types of AMD, one in each eye. She announced her diagnosis in 2012 but reassured the public that her condition wouldn’t prevent her from continuing to perform.

      In the early stages of her condition, she would have her script printed out in enlarged fonts. As her condition deteriorated, she lost her ability to read. Nowadays, friends or family members read and repeat the lines aloud to help her memorize her script.

      In a recent interview, Dench shared that her vision loss spurred her to ‘find a way of just getting about and getting over the things that you find very difficult.’

      While AMD has made performing and completing day-to-day tasks more challenging, it hasn’t prevented Dench from leading a full and happy life.

      Frequently Asked Questions with Dr. Greg Evans

      Q: What are some risk factors for developing age-related macular degeneration?

      • A: AMD risk factors include family history, being over 55 years old, smoking, obesity, cardiovascular disease and high cholesterol. If any of these apply to you, speak with your low vision optometrist regarding the steps you can take to lower your risk of developing this vision-robbing eye disease.

      Q: What are the first symptoms of AMD?

      • A: At first, you may notice gradual or sudden changes in your vision. Straight lines may begin to appear distorted, or dark, blurry areas or whiteout may appear in the center of your vision. Dry AMD can sometimes take up to a decade to progress. With wet AMD, symptoms often appear and progress quickly, with very little warning.

      Reading Tips For Those With Low Vision

      Senior Woman Reading 640×350

      For people with low vision, reading can feel like running a marathon. Many stop reading altogether because what used to be enjoyable and effortless now requires effort and adjustment to using peripheral vision.

      Fortunately, there are many low vision devices that can make reading easier and more rewarding for people with glaucoma, retinitis pigmentosa, macular degeneration and other low vision conditions.

      Below is a list of low vision magnifiers, aids, devices, and strategies that can help people with low vision read more easily and comfortably.

      Low Vision Devices for Reading

      Reading Magnifier

      The most commonly used visual aid for reading is a hand-held magnifier.

      Magnifiers with the appropriate power enable people with low vision to read the text of medicine bottles, food labels and oven dials, among other things. Magnifiers come in a variety of sizes and shapes, including compact pocket magnifiers, full-page illuminated magnifiers, and magnifiers with adjustable supports.

      Magnifiers are not well suited for continuous reading, like books or newspapers. They work well for spot reading, like labels, dials and medicine bottles. In general, the larger the magnifier, the less powerful it is. Also, the power markings on the magnifier are not standardized, so two magnifiers both marked “3x” are probably not the same.

      It is best to have your low vision optometrist recommend the right magnifier for your needs.

      Video Magnifier

      While traditional optical magnifiers are generally helpful, some people benefit more from a video magnifier.

      A video magnifier, also known as closed-circuit television (CCTV), is a device that uses a camera to send magnified images (up to 50x or greater) to a large desk monitor or television screen.

      Video magnifiers have many advantages over optical magnifiers in that they have variable magnification and can improve contrast. However, they are not as convenient as optical devices and are much more expensive.

      Portable Electronic Magnifiers

      A portable electronic magnifier resembles a tablet or iPad. When holding it in front of your reading material you can see the magnified version of the text on the device’s LED screen.

      High-Power Reading Glasses

      A person with significant visual impairment may be able to use strong magnifying reading glasses to view fine print. These eyeglasses magnify the print size to allow easier reading.

      Strong reading glasses or “microscope” glasses are more convenient for continuous reading, like newspapers and books.

      Microscope reading glasses require a closer reading distance which does take some adapting. However, they allow much greater comfort and speed when reading for enjoyment.

      Tele-Microscopic Glasses

      Tele-microscopic lenses are prescription lenses that are installed in a telescope-like device and placed on top of the glasses. They can be prescribed for one or both eyes and enable a person with low vision to read, write, use a computer, and accomplish other activities from a comfortable distance.

      Certain low vision devices are custom-made for a patient’s specific needs. A prescription from your eye doctor may be required.

      Tele-microscope glasses, or “reading telescopes” afford a much greater reading distance, which some find more comfortable. They are a bit heavier than microscope glasses but are much more versatile in their use.

      More strategies to help your reading

      Increase Contrast

      When reading, it’s best to have a sharp contrast between the text and its background. Newspapers, for example, don’t have much contrast because the grey characters are set against an off-white background.

      Many electronic screens allow users to adjust the contrast according to their preferences, such as black lettering on a yellow background or black lettering against a white background.

      Increase Lighting

      Increasing the amount of lighting and choosing the appropriate lighting for the setting can considerably improve reading ability and boost comfort. For example:

      Direct light – Using an adjustable gooseneck lamp that allows you to focus the light directly onto the reading material can be helpful. We recommend “gooseneck” with lower strength bulbs for better lighting and less heat.

      Sunlight – Sitting near a window to get natural sunlight while reading a book or other written text is ideal.

      Large-Print Books or Larger Fonts

      Large-print books include larger fonts, better contrast and more spacing, making it easier and more enjoyable to read.

      Adjust Settings on Your Smartphone

      Smartphones feature special settings for people with low vision. These features are wide-ranging and include the ability to select larger lettering to SMS messaging that the phone can read out loud.

      Coping with low vision isn’t simple. However, developing your own life hacks and methods can make reading easier. Take your time to find what works best for you. Eventually, you’ll find the best solutions for your specific needs.

      Contact Low Vision Center At Rancho Mirage Eye Care Optometry to find out which low vision aids and devices are right for you.

      Frequently Asked Questions with Dr. Greg Evans

      Q: What is a low vision exam?

      • A: A low vision exam includes components that are not usually part of a standard eye exam. Dr. Greg Evans will analyze the nature of your vision loss after testing your visual acuity. This will aid the doctor in determining how low vision is affecting you and your ability to perform day-to-day activities. Dr. Greg Evans will then describe how certain low vision glasses and various low vision aides can help you regain as much daily function as possible.

      Q: Does low vision mean blindness?

      • A: No. Low vision is vision loss that can’t be corrected with glasses, contact lenses or surgery. However, it’s not considered blindness, as some sight remains. This allows a person to still use the sight available and benefit from various low vision devices.

      5 Adjustments To Make Around The House For People With Low Vision

      senior couple at home 640×350

      Home improvement can upgrade the look and feel of your living space. But for those with low vision, the right setup can be the difference between constantly relying on others and functioning independently.

      At Low Vision Center At Rancho Mirage Eye Care Optometry, we understand the importance of feeling self-sufficient and continuing to do the things you love after vision loss. To that end, we’ve shared a few tips to help you adapt your home and help you live a higher quality of life.

      1. Increase the Color Contrast

      Make sure you strategically place bright contrasting colors around the house to help identify and locate items. For example, keep your phone, keys or wallet in a bright tray or dish so they’re easy to find.

      Consider replacing cabinet and doorknobs with colors that stand out. For instance, choosing black knobs on white cabinets and doors will make it easier for you to find and grasp them. You can also add brightly colored tape to kitchen utensils and remote controls. We further recommend you place brightly colored non-slip tape or a contrasting or textured strip of flooring in front of a staircase to alert you to the stairs.

      Contrasting colors are just as useful for preparing food and beverages. Pour dark liquids (like coffee or tea) into white mugs, and light liquids (like milk) into darker colored mugs. If your mugs blend in with the color of your countertops, consider purchasing new ones in a contrasting color.

      2. Furnish Thoughtfully

      People with low vision may struggle to maintain eye contact or recognize faces of those who are far away. For this reason, it’s worth moving sofas and armchairs close together.

      Moreover, when choosing furniture, focus on differences in texture and size. It’s often easier for someone with low vision to identify a piece of furniture through touch rather than sight.

      3. Bring in More Light

      Think floor lamps, desk lamps, and sheer window curtains — anything that increases lighting will make it easier to read, cook, do crafts and other activities.

      Desk lamps should be bright and be fitted with a lightbulb that’s at least 75w.

      4. Use Technology

      Consult with your low vision optometrist regarding which optimal low vision digital aids and devices you can use to help you read and identify household items with ease. Some options include closed caption television video magnifiers, handheld video magnifiers and wearable digital headsets.

      5. Make Your Space Hazard-Free

      Consider removing rugs or securing their edges to prevent accidental trips and falls, and ensure that all pathways are free of electrical cords and clutter.

      If your home has a tiled floor, be sure there aren’t any loose, uneven or broken pieces that can easily be overlooked. Additionally, when washing your floors, opt for non-glare detergents that don’t leave a waxy finish.

      Living with low vision can be difficult, but making your home more suited to your visual needs will make daily living easier.

      Your low vision optometrist at Low Vision Center At Rancho Mirage Eye Care Optometry makes it a priority to provide personalized care and attention to ensure the best possible outcome. After thoroughly examining your eyes and assessing your degree of vision loss, Dr. Greg Evans will recommend low vision aids and devices to help you maximize your vision and enjoy a better quality of life.

      If you or a family member live with low vision or have been diagnosed with a sight-threatening eye condition, call Low Vision Center At Rancho Mirage Eye Care Optometry to schedule a low vision consultation today.
