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.

Can We Stop Myopia From Progressing?

boy and a girl with myopiaIf you think more powerful prescription glasses are the right solution to keep your child’s myopia from getting worse, think again. Talk to us about myopia management, which can slow the progression of myopia (nearsightedness) by up to 78%.

How Does Myopia Worsen?

In nearsighted people, the cornea, the clear outer layer of the eye, is more curved than in non-myopes. This elongated eyeball shape refracts incoming light in front of the retina rather than directly on it. The result? Blurred vision.

In other words, the longer the eyeball, the more severe the myopia.

The following can contribute to myopia progression:

  • Eye growth – as children grow, so do the eyeballs. And in certain cases, they become elongated (myopia).
  • Hereditary factors – if one or both parents have myopia, the condition is likely to progress at a rapid pace.
  • Not enough outdoor time –1 to 2 hours a day outdoors is recommended to prevent myopia progression.
  • Excessive screen time – myopia development and progression have been linked to extended screen time.

What Is Myopia Management?

Myopia management is a custom-designed treatment plan that identifies slows or stops myopia progression. Our optometrists provide diagnostic eye exams and create a myopia management program to keep your child’s nearsightedness in check.

Why Is Myopia Management Important?

Myopia doesn’t just affect your child’s ability to see distant objects; it can increase your child’s risk of developing these serious eye problems in adulthood:

  • Glaucoma
  • Cataracts
  • Myopia macular degeneration
  • Retinal detachment

The sooner your child begins myopia management, the better the chances of slowing myopia’s progression and reducing the risk of eye diseases later in life.

Myopia Management Can Preserve Your Child’s Vision

If you’re eager to preserve your child’s eyesight now and in the future, myopia management can help. Book an appointment at Myopia Management Center At Rancho Mirage Eye Care Optometry today!

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: Does screen time affect myopia?

  • A: Yes. In a study published in The Lancet Digital Health (October 2021), an international team of researchers found that at least 3 hours of screen time per day can increase the risk of developing myopia by 30%. Other research suggests that reducing your child’s screen time and encouraging more outdoor activities can prevent myopia and keep it from progressing.

Q: When should one start myopia management?

A: As soon as possible! Research shows that the earlier a child becomes myopic, the faster their myopia will progress. Act quickly if you want to have the greatest impact on slowing myopia progression.

June 27 Is National Sunglasses Day!

Monday, Jun 27, 2022 is National Sunglasses Day, so grab your favorite pair of sunnies and celebrate!

Many people think sunglasses are little more than a fashion accessory or a way to minimize glare while driving.

But the truth is that wearing sunglasses is vital if you want to safeguard your eye health and vision.

Why Sunglasses are Important

The number one reason to wear sunglasses is that they prevent ultraviolet (UV) light from entering your eyes.

UV light has been shown to age every part of the eye, from the delicate outer eye tissue to the tiny structures within the eye itself. Chronic UV exposure raises your risk of developing cataracts, age-related macular degeneration and corneal damage.

The skin on your eyelids is the thinnest skin of your body, and UV light exposure can further thin eyelid skin, leading to premature aging and the appearance of dark circles and under-eye bags. Additionally, wearing sunglasses can help prevent wrinkles because you’ll squint less in the sunshine. Who knew sunglasses can be a key player in your anti-aging routine?

Moreover, UV light has been shown to slow the cornea’s ability to heal itself, making sunglasses a medical necessity for people who’ve recently had eye surgery like LASIK, or those who frequently wear contacts (overwearing contacts can irritate the cornea).

Finally, sunglasses are a fun way to show the world your personality and accessorize any outfit.

Activities for National Sunglasses Day

Not sure how to celebrate National Sunglasses Day? Here are a few ideas you may enjoy.

Sport your favorite pair of sunglasses during an outdoor activity, whether it’s a barbecue with friends, a concert at a stadium or time spent in the park.

You can also celebrate National Sunglasses Day by gifting a pair of quality sunglasses to a friend, spouse or child!

No matter how you choose to celebrate National Sunglasses Day, we hope you enjoy and keep your eyes protected.

For all matters related to eye health, ​​Rancho Mirage Eye Care Optometry in Rancho Mirage is here for you. Contact our eye doctor today!

FAQ With Our Optometrist

Should kids wear sunglasses?

Yes, children of all ages should wear sunglasses whenever they’re outdoors. In fact, it’s crucial because a child’s crystalline lens within the eye is much more clear than an adult’s, letting more light through. Contact us to learn more about kids’ eye health or to schedule an eye exam.

Can sunglasses block blue light?

Sunglasses with lenses that have a yellowish tint offer the most amount of blue light protection, from the sun and other sources. If you’re interested in blocking the blue light that’s emitted from your digital devices, speak with us to determine if computer glasses are right for you.

What’s The Connection Between Dry Eye And Asthma?

Woman with Dry Eye And AsthmaResearchers have already established several known risk factors for developing dry eye syndrome: the quality of your tears, excessive screen time, air pollution, hormonal fluctuations, aging, certain medications and medical conditions, and even one’s gender (females are more prone).

Here’s another risk factor that’s recently been added to the list: having asthma.

Asthma is a disease of the lungs that affects about 300 million people around the globe. Symptoms include wheezing, chest tightness, coughing and breathlessness.

Fortunately, asthmatic patients are usually able to do the activities they enjoy by taking prescription medications that facilitate easier breathing.

But medical professionals have noticed that individuals taking these medicines, and sometimes even asthmatic patients who don’t, have a higher incidence of dry eye syndrome.

If you have asthma or any other risk factors for dry eye syndrome, let your eye doctor know. The eye care professionals at Dry Eye Center At Rancho Mirage Eye Care Optometry can identify the underlying cause of your dry eye symptoms and provide you with lasting dry eye relief.

What is dry eye syndrome?

Dry eye syndrome occurs when the eyes consistently lack proper lubrication, either due to insufficient tears or tears that lack essential oils.

Here’s a list of the common dry eye symptoms:

  • Burning, gritty or itchy eyes
  • Eye dryness
  • Red or painful eyes
  • Blurred vision
  • Stringy mucus around the eyes
  • Light sensitivity
  • Difficulty or inability to wear contact lenses
  • Feeling that something is stuck in your eye

What Causes Dry Eye Syndrome?

Most cases of dry eye syndrome result from the dysfunction of the meibomian glands in the eyelids, which produce the vital oils needed for healthy tears, and which reduce tear evaporation. But dry eyes can also be caused by some autoimmune diseases, hormone replacement therapy, certain medications and, it appears, asthma or the medications that treat it.

Environmental factors that can bring on dry eye syndrome include exposure to wind or airborne irritants, pollution, infrequent or incomplete blinking (people blink less when they use digital devices), heating, air conditioning and dry weather. Certain makeup products, including mascara, and application methods such as applying makeup on the eyelid margin, can block the glands that lubricate the eyes.

Can Dry Eye Syndrome Be Cured?

There is now a wide range of treatment options that can successfully manage your dry eyes. The key is to allow us to find and target the underlying cause of your condition, so we can create a plan to minimize and sometimes eliminate your dry eye symptoms.

What’s the Link Between Asthma and Dry Eye Syndrome?

Several studies have examined the relationship between asthma and dry eye syndrome and found that although a link exists, researchers aren’t sure exactly why.

One study, published in BMJ Open (2019), found that asthmatic people of Australian, Caucasian and Asian descent have higher rates of dry eye syndrome than those without asthma.

Another study, published in Medicine (2020), established a significant link between asthma and dry eye syndrome, and found that children with asthma tend to have an unstable tear film — a common cause of dry eyes.

One hypothesis is that asthma medications, like inhaled corticosteroids, oral antihistamines and leukotriene receptor antagonists may contribute to eye dryness by inhibiting tear production, but further research is needed.

Could asthma itself be the culprit? Possibly, but more research is needed for a better understanding. What is known, however, is that having low blood oxygen levels caused by severe asthma can deprive the front section of the eye (the cornea) of oxygen, potentially leading to dry eye syndrome.

What’s the Bottom Line?

Research shows that having asthma may increase your risk of experiencing dry eye symptoms.

If you have asthma, speak with your optometrist about lowering your risk of developing dry eye syndrome and make sure to bring all of your asthma medications to your next eye exam.

If you already have certain symptoms of dry eye syndrome, promptly contact Dry Eye Center At Rancho Mirage Eye Care Optometry to schedule a dry eye consultation. We’ll create a personalized treatment plan so you can enjoy long-term relief.

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 at-home remedies can relieve dry eye syndrome?

  • A: Make sure to stay hydrated and wear sunglasses whenever outdoors. If you use an indoor heater or air conditioner, direct the airflow away from your face. Use a humidifier at home and at work. You can also try using a warm eye compress. Ask your eye doctor for instructions on how to do so. But keep in mind that trying to manage dry eye syndrome without seeing a dry eye optometrist won’t be as effective.

Q: How is dry eye syndrome treated?

  • A: The type of treatment depends on what’s causing the symptoms. For example, if premature tear evaporation is the problem, your optometrist may prescribe eye drops. Or if your meibomian glands aren’t functioning as they should, unclogging the glands may do the trick. Medicated eye ointment or drops may be prescribed, or we may recommend certain in-office dry eye treatments. Each treatment plan is carefully formulated with your eyes and lifestyle in mind.

4 Facts You Should Know About Scleral Lenses

Woman wearing Scleral Lenses scenic viewDo you have keratoconus or another type of corneal irregularity due to a medical condition or post-surgical complications? Are you considering giving up conventional contacts due to dry eye syndrome?

Consider scleral contact lenses! Contact Rancho Mirage Eye Care Optometry in Rancho Mirage to learn more and to discover a new sense of freedom with sclerals!

What Are Scleral Contact Lenses?

Sclerals are customized rigid gas permeable lenses that are wider than conventional lenses. Their name reflects the fact that they vault over the cornea and rest on the sclera, the white part of the eye.

Scleral contact lenses are 14-24 mm in diameter, while regular contacts are 9mm. This gives sclerals room to accommodate irregularly shaped corneas and provides a reservoir of moisture to soothe dry eyes.

4 Essential Facts About Scleral Contact Lenses

1. Sclerals Are the Right Fit for Irregularly Shaped Corneas

Keratoconus, astigmatism and complications from eye surgery can all result in an irregular-shaped cornea, and wearing contact lenses when your eyes are hard to fit can be challenging. Because sclerals are larger than regular contacts and don’t sit on the sensitive cornea, they provide lots of space and a comfortable fit.

2. Scleral Contact Lenses Can Reduce Dry Eye Symptoms

If you have dry eye syndrome, you may be tempted to give up on wearing contacts altogether. Scleral lenses are ideal for people with dry, itchy and irritated eyes. A lubricating pool of saline solution inside each scleral lens can reduce or even eliminate dry eye discomfort.

3. Sclerals Create a Wider Field of Vision

The width of sclerals not only makes them more comfortable but can extend your field of vision. Their diameter can expand your optic zone and make your peripheral vision sharper and clearer.

4. Sclerals Are Durable and Long-Lasting

Rigid gas permeable contact lenses, including scleral lenses, last longer than conventional soft contacts. Their durable materials are designed to resist wear and tear, which is also why scleral lenses don’t require frequent replacements.

Enjoy the convenience and clear vision scleral lenses by scheduling an appointment with Specialty Contact Lens Center At Rancho Mirage Eye Care Optometry and discover whether scleral lenses are the right choice for you.

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: Can I exercise with scleral lenses?

  • A: Scleral lenses are ideal for people who lead active lives—whether you’re a professional athlete or just like to pass a ball around with friends at the park. Thanks to their greater width, scleral lenses stay in place on the eye more than standard lenses while simultaneously providing clear crisp vision. That said, scleral lenses aren’t recommended for martial arts and other sports with a higher-than-usual rate of facial injuries.

Q: If I have keratoconus, can I avoid corneal surgery with scleral lenses?

  • A: A study published in the Journal of Ophthalmology (2018) that examined 51 patients with advanced keratoconus found that 40 of them didn’t need surgery after wearing scleral lenses. In fact, wearing them reduced the need for corneal transplant or keratoplasty by half during a 5-year period.

Could Working From Home Be Hurting Your Vision?

Working at home is a great way to ditch your commute and enjoy more flexible hours, but there can be an unexpected consequence—digital eye strain. If you’re like many workers, you probably spend most of your day on a computer or other digital device, and likely experience the headache, blurred vision, sore eyes or achy back so common with digital (computer) eye strain.

In contrast to being in the office, where workers take coffee breaks and socialize, working solo at home often translates into spending more time on the computer without breaks, and often beyond the typical 9 to 5 schedule. This can increase the likelihood of developing digital eye strain.

What Is Digital Eye Strain?

Digital eye strain, also called computer vision syndrome (CVS), affects an estimated 70% of adults, especially those between the ages of 18 and 34.The eye strain results from extended hours focusing on a computer screen, and may be worsened by hours of exposure to blue light, high-energy visible light emitted by digital screens.

Blue light can cause short-term eye strain and discomfort, and scientists are researching whether it could also be linked to serious eye conditions, such as age-related macular degeneration (AMD) and cataracts.

Moreover, staring at a screen, or even a printed book, causes people to blink up to 66% less often. Blinking is essential as it hydrates your eyes and stimulates the release of oil from the tiny glands in your eyelids. This oil also prevents tears from evaporating too quickly, thus drying out the eyes. Dry eyes can cause blurry vision, which further exacerbates eye strain.

What Are the Symptoms of Digital Eye Strain?

The following are common symptoms of digital eye strain:

  • Blurry vision
  • Eye soreness
  • Headaches Dry eyes
  • Light sensitivity
  • Neck, back and shoulder pain

How Can I Prevent Digital Eye Strain?

No need to ditch your job in order to avoid eye strain. There are other, more practical, ways to lessen the negative impact of screen time on our eyes. Below are some helpful tips.

Take Breaks

Even if you aren’t at the office and may not have co-workers to hang out with at the coffee machine or water cooler, make sure to take frequent breaks that don’t require screen time. Perhaps take a walk or reward yourself with a short nap. These breaks not only give your eyes a rest, but can rest your mind for a few minutes so you can work more efficiently.

Consider adopting the 20/20/20 habit. For every 20 minutes you spend in front of a screen, take a 20-second break and look at something 20 feet away. This will prevent you from overstraining your eyes and will encourage you to blink more, providing your eyes with much-needed hydration.

Adjust Screen Brightness

Bright screens can place a significant burden on your eyes. Simply adjusting your screen’s brightness can help rest your eyes.

See Your Eye Doctor

If you spend prolonged periods in front of the screen, it’s important to schedule an eye exam with your eye doctor to discuss whether you would benefit from lubricating eye drops or a pair of computer glasses. These computer glasses (or blue light glasses) allow your eyes to relax and make you feel as if you’re focusing on faraway objects. They also reduce glare and filter out blue light.

Whether you’re suffering from any of the symptoms related to digital eye strain or simply want to prevent it, we invite you to book an appointment with Rancho Mirage Eye Care Optometry in Rancho Mirage. With the right eye care and work habits, you should be able to successfully and quickly reduce and prevent eye strain.

Q&A With Our Optometrist

How long does it take to recover from computer eye strain?

If you don’t have an underlying eye condition, symptoms of digital eye strain can sometimes disappear within a few hours or days. But if you have recurrent eye strain, speak with your eye doctor, as the right eye drops or computer glasses could improve your visual comfort and quality of life.

Can digital eye strain affect my work productivity?

You may think spending hours in front of a computer screen will improve your productivity, when in reality, it may have the opposite effect. According to a study at the University of Alabama/Birmingham School of Optometry, even minor vision problems, such as eye strain, disrupt worker productivity by at least 20%.

So make sure to take steps to control lighting and glare on the device screen and establish proper working distances and posture for screen viewing. To learn more and to alleviate or prevent eye strain, contact Rancho Mirage Eye Care Optometry today.

How Myopia (Nearsightedness) Can Affect Your Child’s Life

child in school unable to work due to myopiaMyopia (also known as nearsightedness) is nothing short of a global epidemic. According to the World Health Organization, 27% of the world’s population has myopia, and that number is expected to rise to 50% by 2050.

Myopia almost always begins in childhood and can progress rapidly until the late teens or early twenties. Children with moderate or severe myopia are at a much greater risk of developing eye conditions that can cause vision loss and even blindness.

Fortunately, there are proven ways to slow and sometimes halt myopia’s progression during childhood, to safeguard your child’s vision for a lifetime.

What Causes Myopia?

Myopia is often inherited, but other risk factors include spending too many hours indoors engaged in ‘near work’ like reading and staring at electronic screens.

Myopia occurs when the eyeball grows longer, which causes light rays to refract incorrectly, focusing images in front of your retina instead of on your retina. This results in blurry vision.

How Myopia Can Impact Your Child

Nearsightedness can affect your child in many ways:

Difficulties at School and While Playing Sports

Sometimes parents don’t realize their child is experiencing myopia-related blurry vision until they notice a recurrence of poor grades on their report cards or tests.

Eyestrain

Trying to focus on faraway objects to see them with more clarity when they appear blurry often results in eyestrain. Yet many parents and teachers don’t realize that a child’s headaches, tired, burning, itchy eyes, blurry vision, neck and shoulder pain may be caused by myopia.

Poor Sports Performance

When you try to catch a ball, aim for a target or locate a goal post, you need to see clearly at a distance. Nearsightedness can interfere with a child’s ability to succeed on the sports field.

How Does Myopia Affect Quality of Life?

Myopia isn’t just about difficulty seeing faraway objects. Rapidly progressing myopia increases a child’s risk of developing serious eye conditions in the future. They include:

  • Glaucoma
  • Retinal detachment
  • Cataracts
  • Myopic maculopathy

What is Myopia Management?

Myopia management is the area of optometry devoted to slowing down and even halting the rapid progression of myopia in childhood. Myopia can be managed thanks to a customized treatment program provided by an eye doctor near you. The sooner a child’s myopia is managed, the lower the risk of myopia-related complications in adulthood.

To find out how myopia management can transform your child’s vision, confidence and success in life, schedule an appointment with Dr. Greg Evans today.

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: Can Myopia Be Cured?

  • A: While there’s no cure for myopia, myopia management has been scientifically proven to slow and at times halt myopia’s progression. LASIK and other laser surgeries aren’t an option until a child with myopia reaches adulthood and their eyes have stopped growing (meaning, their eye prescription has stopped changing).

Q: What is High Myopia?

  • A: High myopia is a more severe form of regular myopia, usually above -3.00 dioptres. Children who develop high myopia often have rapidly progressing myopia that begins in early childhood and are at a higher risk of developing serious sight-threatening eye diseases later in life, such as glaucoma, macular degeneration and cataracts. Myopia management can help slow or halt the rapid progression of myopia, offering the child a higher quality of life in the long term.

    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.

      What Exactly is an Eye Chart?

      If there’s one aspect of optometry that everyone recognizes, it’s the traditional eye chart, with its rows of big letters on top, which gradually become smaller the farther down you go. This chart is usually known as the Snellen chart.

      Yet how much do you really know about this eye chart? Are all eye charts the same? How are these eye charts used? And when were they invented?

      Here’s everything you need to know about eye charts and more!

      What is an Eye Chart?

      An eye chart is one of the tools your eye doctor uses to assess your eyesight. Based on how well you can see various letters on the chart, your optometrist will determine whether you have myopia (nearsightedness), hyperopia (farsightedness), presbyopia (age-related farsightedness) or astigmatism, and will measure the prescription that will give you the clearest, most comfortable vision.

      Are All Eye Charts The Same?

      There are a number of variations to the standard Snellen eye chart. The one an eye doctor uses depends on the personal needs and abilities of the patient. For example, eye doctors will use charts with pictures or patterns for younger children who may not have learned to read or identify letters and numbers.

      There are also certain charts that specifically measure distance vision, while others are better for measuring near vision.

      History of the Snellen Eye Chart

      The Snellen eye chart was developed by Dutch eye doctor Hermann Snellen in the 1860s. Before this standardized eye chart was developed, each eye doctor had their own chart that they preferred to use.

      Having so many different eye charts made it impossible to standardize the vision correction available to patients. Eyeglass makers didn’t receive the defined measurements they needed to accurately design, manufacture and measure the optical prescriptions their patients needed.

      For the first time, the Snellen eye chart allowed a person to provide a standardized prescription from any eye care provider they chose to any eyeglass maker, and get the same optical lenses to accurately correct their vision.

      How The Snellen Chart Is Used in Eye Exams

      The standard Snellen chart displays 11 rows of capital letters, with the first row consisting of a single large letter. The farther down the chart you go, the smaller the letters become.

      Your Rancho Mirage eye doctor will ask you to look through a phoropter – an instrument used to test individual lenses on each eye during an eye exam – and look at the Snellen chart placed 20 feet away. Your eye doctor will prescribe the lenses that provide you with the clearest and most comfortable vision.

      In many offices, where 20 feet of space may not be available, you’ll be asked to view the chart through a mirror. This provides the same visual experience as if you were standing 20 feet away.

      If you have 20/20 vision, it means you can see what an average person can see on an eye chart from a distance of 20 feet. On the other hand, if you have 20/40 vision, it means you can only see clearly from 20 feet away what a person with perfect vision can see clearly from 40 feet away.

      If you have 20/200 vision, the legal definition of blindness, this means what a person with perfect vision can see from 200 feet away, you can see from 20 feet away.

      Does 20/20 Visual Acuity Mean Perfect Vision?

      No. While eye chart tests identify refractive errors, they can’t detect signs of visual skill deficiencies or diseases such as glaucoma, cataracts or macular degeneration. These are diagnosed using advanced equipment as part of a comprehensive eye exam with your local Rancho Mirage eye doctor. Early diagnosis and treatment of eye conditions are essential to ensuring long-term vision and eye health.

      Q&A With Your Local Optometrist

      How do you keep your eyes healthy?

      You only have one set of eyes – don’t take them for granted!

      Make sure to implement the following habits for healthy eyes (and body). These include:

      • Eating a balanced diet rich in fiber, fruits and vegetables
      • Drinking plenty of water to hydrate your body and eyes
      • Not smoking, and avoiding 2nd-hand smoke
      • Wearing sunglasses to protect your eyes from ultraviolet (UV) rays
      • Maintaining normal BMI with regular exercise
      • Regular visits to your eye doctor as recommended

      What health conditions can an eye exam detect?

      A comprehensive eye exam can often detect certain underlying diseases that can threaten your sight and eye health, such as diabetes, high blood pressure, high cholesterol, tumors, autoimmune conditions and thyroid disorders. This is why having your eyes checked regularly is key. The earlier the diagnosis and treatment, the better the outcome and the higher your quality of life.

      The Link Between Dry Eyes and Depression

      The Link Between Dry Eyes and DepressionDepression is a serious illness that impacts a person’s mood and emotional well-being. It creeps into all areas of a person’s life, and can become life-threatening if left untreated.

      Not only does depression impact mental health; it can manifest as physical symptoms, too, like insomnia, chronic pain and inflammation, weight loss or gain and heart problems, among others. These physical problems can worsen depressive thoughts — sometimes leading to a vicious cycle.

      Interestingly, many patients with depression also suffer from severe dry eye symptoms. The question is, how are these two conditions related?

      What is Dry Eye Syndrome?

      Dry eye syndrome, also known as dry eye disease, is a chronic condition that results from inadequate lubrication of the eyes. Ocular hydration is crucial when it comes to keeping your eyes healthy and your vision clear. Your tears are responsible for maintaining this necessary hydration, and in healthy eyes fulfill their unique mission each time you blink.

      Your tear film is made up of three layers, consisting of oil, water and mucus. If any of these layers become compromised, inadequate tear quality or insufficient tear quantity can result and lead to a host of uncomfortable dry eye symptoms.

      The most common dry eye symptoms include:

      • Dry eyes
      • Red or irritated eyes
      • Itchy eyes
      • Gritty eyes
      • Light sensitivity
      • Blurry vision

      Can Depression Cause Dry Eye (or Vice-Versa)?

      This is what researchers are trying to find out.

      In a March 2022 study published in JAMA Ophthalmology, researchers examined the link between depression and severe dry eye symptoms. The study followed 535 dry eye patients for an entire year.

      After a year, the patients who tested positive for depression had more severe dry eye symptoms than the patients who didn’t have depression. Their symptoms were measured based on the Ocular Surface Disease Index (OSDI), Brief Ocular Discomfort Index and composite dry eye disease sign score.

      Additionally, severe depression was associated with more severe dry eye symptoms at baseline, six months, and one year.

      The study concluded that depression was associated with more severe dry eye symptoms, which suggests that among patients with moderate to severe dry eye syndrome, those with depression may be likely to have more severe dry eye symptoms.

      The researchers said further research is needed to learn exactly why people with depression have more severe dry eye symptoms than those without depression.

      Could the sometimes debilitating symptoms of dry eye syndrome actually cause depression and anxiety?

      A 2016 dry eye study published in Nature concluded that chronic discomfort and pain from dry eye symptoms can negatively affect the cognitive processes, sleep, mood and mental health. The researchers urged eye doctors to be aware of the higher incidence of dry eye syndrome in people with depression, whatever the underlying cause.

      Can Antidepressants Cause Dry Eye Symptoms?

      Yes. Antidepressants have been shown to increase dryness in the body, including the eyes. These medications work by blocking signals between nerve cells, which can result in insufficient tear production and dry eye syndrome.

      If you’re taking an antidepressant, be sure to inform your eye doctor during your consultation.
