Wearing Colored Contact Lenses This Halloween? Beware and Take Care!

Countless adults, teens and even children will be wearing colored contact lenses this Halloween, but few are aware of the risks involved. Ever wondered what those cat-eye contacts are doing to your eyes? If you got them without a prescription, beware of health complications.

Enjoy a safe and happy Halloween by educating yourself and others about the dangers of wearing colored contact lenses without a prescription.

Why Can Over-The-Counter Colored Contact Lenses Cause Eye Damage?

Contact lenses made to change one’s appearance go by many names: cosmetic, theatrical, Halloween, circle, decorative, colored, or costume contact lenses. While it’s illegal to sell colored contact lenses without a prescription, authorities rarely enforce the law — which means they’re still accessible in many places.

Many people believe that wearing non-prescription color contact lenses can cause no harm. This unfortunate myth has led to many contact lens complications. For instance, when a person feels that a contact lens is “dry”, it could be because the lens is not a good fit. Ideally, the lens should follow the contour of the eye, and stay centered, with enough lens movement to allow tear exchange beneath the lens.

Many eye diseases can be quickly and easily diagnosed during a comprehensive eye exam. If you were diagnosed with an eye disease, such as Cataracts, Glaucoma, Macular degeneration, Diabetic retinopathy, or Dry eye, you may be overwhelmed by the diagnosis and confused about what happens next. Will you need medications or surgery – now or in the future? Our Richmond Hill eye doctor has prepared the following answers to your questions about eye disease.

Furthermore, non-medical colored contact lenses are often produced by unlicensed manufacturers that tend to use inferior plastic and toxic materials, such as lead (often used in lens coloring), which can get absorbed through the eyes into the bloodstream. These illegal lenses may also contain high levels of bacteria from unsanitary packaging, shipping, and storage conditions.

Therefore, purchasing any kind of contact lenses without a prescription or medical oversight can result in a variety of eye complications, such as corneal abrasions, eye sores, conjunctivitis, other eye infections, vision impairment and, in rare cases, even permanent vision loss.

Even if you have perfect vision, all contact lenses, including colored contacts, require a prescription and proper fitting by an optometrist.

Contact us at Feinstein Eyecare and make an appointment with us to get properly examined for a contact lens prescription.

Summer Heat Wave and Your Eyes

This summer, heat waves with scorching temperatures have hit communities nationwide, making an already hot summer even hotter. With high temps and heat waves in certain areas, it’s now more important than ever to protect yourself.

For best practices and tips for maintaining healthy vision in the summer heat, talk to us at Feinstein Eyecare.

How Can Heat Affect Vision?

Staying out in the sun too long can give you a sunburn and make you feel exhausted. Did you know that it can affect your vision, too?

If you get dehydrated, lack of moisture can make it hard for your eyes to naturally produce enough tears, which can contribute to seasonal dry eye. If you already have dry eye, extremely dry heat can exacerbate your symptoms of itchy, red, sore, and irritated eyes.

Do you sit in front of a fan or air conditioning system? That may feel great, but it can also contribute to dryer and less comfortable eyes.

To give your eyes some temporary relief, keep artificial tears on hand. If your eyes still feel dry or uncomfortable, contact Feinstein Eyecare.

If You Love the Sun, Read This

Golden sunshine may sound dreamy, but too much isn’t a good thing.

The sun’s ultraviolet (UV) rays can be very harmful, and your eyes are no exception. UV radiation, which can gradually contribute to eye conditions like cataracts and macular degeneration. Dr. Feinstein recommends that you always wear sunglasses with 100% of UVA and UVB light blocking protection. There’s no shortage of trendy and sunglasses, designed with a flair for fashion, so you won’t have to compromise on style while protecting your eyes from dangerous UV rays.

Excessive sun exposure can cause headaches, blurry vision, eye pain, and eyestrain. So while you’re out at the pool, hanging out at the beach, sunbathing, or at a backyard barbeque, pay close attention to how much time you’re outside.

If you love the sunshine, you just need to protect yourself. Wear hats, sunscreen, and, of course, 100% UV protective polarized sunglasses. But if you experience discomfort or symptoms that don’t go away on their own, then it’s time to visit your eye doctor.

Computer Vision Syndrome in the Summer

There’s nothing quite like a family road trip or flying to a vacation getaway over the summer. Yet something about being stuck in the backseat of a car or inside of an airplane makes kids feel closed in and restless. It’s then that many kids will play on a smartphone, iPad, or gaming device over many hours to help pass the time.

When it comes to kids and computer use, they’re just as susceptible to the effects of digital eye strain, also called Computer Vision Syndrome, as adults are. In fact, studies show that 25% of children spend more than 3 hours each day on digital devices.

In the summer, when the heat is sizzling, it’s tempting for kids to spend more time than usual watching TV, using a computer, or playing games on their smartphones. To help ease the effects of digital eyestrain, Dr. Feinstein suggests following the 20-20-20 rule: Every 20 minutes, take 20 seconds to look at something at least 20 feet away. It’s a great way to counteract the effects of Computer Vision Syndrome and let the eyes rest.

This summer, however you choose to beat the heat, don’t forget to protect your vision and keep your eyes strong and healthy. Feinstein Eyecare is always here to help if you have any questions.

Have a great summer!

Many eye diseases can be quickly and easily diagnosed during a comprehensive eye exam. If you were diagnosed with an eye disease, such as Cataracts, Glaucoma, Macular degeneration, Diabetic retinopathy, or Dry eye, you may be overwhelmed by the diagnosis and confused about what happens next. Will you need medications or surgery – now or in the future? Our Richmond Hill eye doctor has prepared the following answers to your questions about eye disease.

Don’t Leave Home Without It

If you have a chronic illness and need to head out of town for a few days, you would never leave home without your medications, right? That’s because you know that if something happens and your meds aren’t with you, you could suffer discomfort or complications to your health. The same is true for your vision. If you suffer from dry eyes, make sure to take artificial tears or medicated eye drops with you when you travel. Preservative-free eye drops are a traveler’s friend. They’re also available as individual strips, which are recommended since there’s less risk of contamination. Running low on disposable contact lenses? Include an extra pair in your carry-on suitcase and stock up on new lenses ahead of time. If you wear eyeglasses, bring a spare set and a copy of your prescription along with you, just in case they get lost or broken. We recommend speaking to Dr. Feinstein before you leave for vacation to make sure your vision needs are all set.

It’s Getting Hot Outside

Usually, most people think of protecting their skin from sunburns when they’re at the beach, by the pool, or just spending time outdoors.

Did you know that your eyes can get sunburned, too? This happens when the cornea is exposed to excessive UV rays. When the sclera (the white part of your eye) looks red, that’s a sign that you’ve got sunburned eyes. You might also notice symptoms like a sudden sensitivity to light, or your eyes may feel like something is stuck in them, or they could feel sore.

The best way to prevent sunburned eyes? Always wear sunglasses with 100% of UVA and UVB light blocking protection. ”

Watch Out for the Pool

Swimming is one of summer’s greatest pastimes. There’s nothing quite like a dip in a pool or ocean to cool off from the sweltering summer heat. While you’re slicing through the water, remember to protect your eyes.

Remove contacts before going swimming, wear goggles while underwater, and rinse your eyes with cold water when you get out of the pool (it helps get the chlorine or salt out). If your eyes feel dry or scratchy after a swim, use some moisturizing eye drops to lubricate your eyes.

Back to School is Sooner Than You Think

Your kids will be back in school before you know it. Help them prepare for the upcoming school year by scheduling an eye exam now. If they need new glasses because their prescription has changed or your teen simply wants a new look for the new school year, come in to Feinstein Eyecare for a consultation and take a look at the newest selection of frames and contact lenses.” Have you had a sudden eye injury or emergency while on vacation? Don’t wait until you’re back home to handle it — seek immediate care today. Certain eye injuries can damage your vision or lead to ulcers, so if you notice symptoms like redness, eye pain, changes to your vision, or flashing light, contact your eye doctor right away.

When 20/20 Vision isn’t Enough For Your Child

New To Contact Lenses? Here Are Our Top 5 Tips!

An Active and Eye Safe Lifestyle

Richmond Hill LASIK – What to Expect After LASIK?

Mental Health and Your Vision

May is Mental Health Awareness Month in the USA; in Canada, Mental Health week is May 6th to 12th. Since 1949, it has been observed throughout the United States as a way of drawing attention to the importance of proper mental health. This year’s theme is #4Mind4Body. The idea is that using elements around us, such as the people in our lives, faith, nature, and even pets, can strengthen wellness and overall mental health.

Did you know that your vision can affect your mental health? While things like stress, trauma, and family history are factors that impact mental health, vision can also impact it.

How Does Vision Affect Mental Health?

Certain types of eye diseases and visual impairments can lead to emotional problems like anxiety and depression. This is particularly common in cases of severe vision loss. Patients with glaucoma, macular degeneration, or diabetic retinopathy, for example, can experience mild to acute vision loss. This can make everyday activities like driving, running errands, watching TV, using a computer, or cooking, a difficult and painful experience. When this happens, it can cause a loss of independence, potentially leaving the person mentally and emotionally devastated.

Like most surgical procedures, LASIK corrective surgery is permanent and irreversible. Although it has very high success rates, LASIK has been considered the cause of depression and mental health issues in a few instances.

Kids’ Vision and Mental Health

Increased screen time among school-age children and teens has been shown to reduce emotional stability and cause repeated distractions and difficulty completing tasks, while also increasing the likelihood of developing nearsightedness.

Kids with visual problems often experience difficulty in school. If they can’t see the board clearly or constantly struggle with homework due to poor vision, they may act out their frustration or have trouble getting along with their peers.

Coping with Vision Problems

One of the most important ways to cope with visual problems is awareness. Simply paying attention to the signs and symptoms — whether the patient is an adult or a child — is a crucial first step.

Family members, close friends, colleagues, parents, and teachers can all play an important role in detecting emotional suffering in those with visual difficulties. Pay attention to signs of changes in behavior, such as a loss of appetite, persistent exhaustion, or decreased interest in favorite activities.

Thankfully, many common vision problems are treatable. Things like double vision, hyperopia (farsightedness), myopia (nearsightedness), amblyopia (lazy eye), and post-concussion vision difficulties can be managed. Vision correction devices, therapeutic lenses, visual exercises, or special prism glasses may help provide the visual clarity you need. Your primary eye doctor can help and a vision therapist or low vision expert may make a significant impact on your quality of life.

How You Can Help

There are some things you can do on your own to raise awareness about good mental health:

  1. Speak Up Often

    Just talking about mental health struggles can be incredibly empowering. Ask for help from family and friends or find a local support group. Be open and honest about what you’re going through and talk with others who are going through the same thing. Remember: you’re not alone.

    If you experience any type of sudden changes to your vision — even if it’s temporary — talk to your eye doctor. A delay in treatment may have more serious consequences, so speak up and don’t wait.

  2. Get Social Developing

    healthy personal relationships improves mental health. People with strong social connections are less likely to experience severe depression and may even live longer. Go out with friends, join a club, or consider volunteering.

  3. Have an Animal

    Having a pet has been shown to boost mental health and help combat feelings of loneliness. Guide dogs can be especially beneficial for people suffering from vision loss. Use Visual Aids If you or a loved one is experiencing mental health issues caused by vision loss, visual aids can help. Devices like magnifiers or telescopic lenses can enlarge text, images, and objects, so you can see them more clearly and in greater detail.

    Kids can benefit from vision correction like glasses, contacts, or specialized lenses for more severe cases of refractive errors. Vision therapy may be an option, too. It is a customized program of exercises that can improve and strengthen visual functions.

Always talk to your eye doctor about any concerns, questions, or struggles.

Thanks to programs like Mental Health Awareness Month, there is less of a stigma around mental health than just a few decades ago. Advancements in medical technologies and scientific research have led to innovative solutions for better vision care.

During this Mental Health Awareness Month, share your share your struggles, stories, and successes with others. Use the hashtag #Mind4Body and give your loved ones hope for a healthy and high quality of life.

School and Vision: 2 Important Partners

It’s February and that means we’re smack in the middle of winter, which is also the middle of the school year. It’s the season when kids fervently hope for snow days and parents hope they don’t happen. As we head towards the second half of the school year, you’ve probably attended a few parent-teacher conferences and discussed your child’s education. Like peanut butter and jelly, school and vision go hand-in-hand. Both are important partners in ensuring that children excel in their learning, extracurricular activities, and relationships with their peers.

ADD/ADHD and Vision Problems

Did you know that certain vision problems can mask themselves as behavioral or learning difficulties? In fact, education experts often say that 80% of learning is visual. A 3rd grader may be misdiagnosed with ADD or ADHD if they display behaviors like being fidgety, having difficulty focusing or concentrating, or having a short attention span. These symptoms may not always be purely behavioral; they could be vision-related. A child who experiences blurry vision, suffers from headaches or eyestrain, or itches their eyes excessively may, in fact, have a refractive error such as myopia (nearsightedness), hyperopia (farsightedness) or astigmatism, or another condition such as convergence insufficiency.

Many eye diseases can be quickly and easily diagnosed during a comprehensive eye exam. If you were diagnosed with an eye disease, such as Cataracts, Glaucoma, Macular degeneration, Diabetic retinopathy, or Dry eye, you may be overwhelmed by the diagnosis and confused about what happens next. Will you need medications or surgery – now or in the future? Our Richmond Hill eye doctor has prepared the following answers to your questions about eye disease.

Undiagnosed myopia, for example can cause these same types of behaviors that are commonly attributed to attention disorders. That’s because if your child has to squint his eyes to see the board clearly, eyestrain and headaches are bound to follow. Struggling with reading or writing is common too. Other vision disorders can cause similar behavior patterns. An additional challenge is that kids don’t always express their symptoms verbally, and often they don’t even realize that other people see differently than do.

This can also impact kids emotionally. When they feel like they’re not keeping up with their peers or their learning is inferior in some way, this may lead the child to act out verbally or even physically.

Distinguishing between colors is an important skill for early childhood development. While color vision deficiency affects both children and adults, kids, in particular, can experience difficulty in school with this condition. Simply reading a chalkboard can be an intense struggle when white or yellow chalk is used. When a teacher uses colored markers on a whiteboard to draw a pie chart, graph, or play a game, this can be a difficult experience for a young student with color blindness. A child, his or her parents, and teachers may even be unaware that the child is color blind.”

What School Vision Screenings Miss

Many parents believe that an in-school vision screening is good enough. However, an eye chart test only checks for basic visual acuity, so kids with blurry or double vision, for example, may be able to pass a vision screening while still struggling to read, write, or focus on the board. Children who have problems with their binocular vision, which means using both eyes together to focus on something, can pass the screening when they use just one eye to read the chart.

Studies show that a whopping 43% of children who have vision problems can successfully pass a school vision screening. This means that the vision test may fail to detect the more subtle but significant and treatable vision problems. Early detection and diagnosis is critical to maintaining healthy eyes. That’s why it’s so important to make eye care a part of your child’s healthcare routine.

The Importance of Yearly Eye Exams

The #1 way to do this is to schedule annual eye exams. Your eye doctor can perform a comprehensive pediatric eye exam to check visual acuity, visual clarity, binocular vision, and screen for any eye diseases or vision problems.

Because children develop so rapidly at different ages, it’s essential that eye exams are done at specific stages of their young lives. In fact, The American Optometric Association (AOA) recommends regular eye exams at age 6 months, 3 years, before school starts, and every 2 years thereafter.

Simply being aware of the tendency to associate a child’s learning issues with a learning disability or attention disorder instead of an underlying vision problem is critical for parents and educators. Both are partners in a child’s education and they must work together to ensure that each child gets the health care and attention he or she needs.

If you notice changes in your child’s schoolwork, behavior with friends or in sports or other after-school activities, it may be time to schedule an eye exam. You’ll want to be sure that your kids have all the tools they need to succeed in school and beyond.

How UV Damages Your Eyes

Sports-Related Eye Injuries

3 Ways Diabetes Can Affect Your Vision and Eyes

Richmond Hill Eye Care – First Aid for Eyes

Exercise and Your Eye Health

Michael C. Feinstein, OD - Local Vision Center in Newark, New JerseyRegular exercise is an essential component of overall health and wellness. It is proven that exercise reduces sickness and disease; it increases strength, immunity, and mental health; and it also helps regulate bodily functions and maintain a healthy weight. Research shows that exercise can lower our risk of chronic conditions such as high blood pressure, heart disease, diabetes, diabetic retinopathy and diabetic macular edema, as well as other eye diseases such as glaucoma, cataracts and wet age-related macular degeneration (AMD).

Whereas, a sedentary lifestyle increases the risk of these diseases and of vision loss, studies show that even moderate exercise at least three times a week can improve the prognosis of the above-mentioned chronic illnesses and reduce the risks of developing vision threatening eye diseases.

Inactivity is an even higher risk factor if you have other co-factors for developing eye diseases, including: a family history, previous eye injury or surgery, diabetes, high blood pressure or very high myopia. A combination of healthy lifestyle habits which include regular exercise and a nutritious diet and tending to your mental and emotional well-being can reduce these risks significantly.”

“Regular exercise is an essential component of overall health and wellness.”

Tips for Incorporating Physical Activity Into Your Day

Make it a priority. Schedule your exercise time into your day as if it is a non-negotiable appointment. Find the time of day that works best – for some that is early morning and for others late at night. Work your way up to a half hour at least three times a week.
Be realistic. You don’t need to become a fitness expert to experience the benefits of exercise. Walking, yoga, swimming, even dancing around the house are all options for staying fit. Find a type of exercise that you love so you will enjoy working this habit into your life.
Just move. Find ways to move your body throughout your day. Park your car a little further away from the mall entrance, take the stairs instead of the elevator or walk or bike to work. Remember, every little bit of movement helps.
Find something you enjoy. Often finding the right exercise is a good stress reliever, and reducing stress will also reduce risk of many chronic diseases.
It’s never too late. Exercise for the elderly can be a challenge especially during the cold winter months, when many seniors can’t get out of the house due to the weather. Even walking up and down the stairs in the house or following an exercise video can be helpful to keep from being sedentary.”

Protection & Prevention of Eye Conditions

If you are exercising outdoors or playing contact sports, make sure to protect your eyes with sunglasses or sports safety glasses to ensure your eye health and safety.

Regular exercise can significantly decrease your risks of certain eye conditions but you still have to ensure that you visit your eye doctor for regular exams. Schedule a comprehensive eye exam every year to ensure your vision and your eyes are healthy and to catch any possible problems as early as possible.”

Eye health and disease prevention are just two of the many health and wellness benefits you gift yourself when you make exercise a regular part of your lifestyle. Speak to your doctor if you have any health issues that need to be considered. At any age or level of physical fitness, you can find some form of exercise that works for you.

Welcome to our New Website

Wearing Colored Contact Lenses This Halloween? Beware and Take Care!

Ocular Migraines

The most well-known part of a comprehensive eye exam is the basic visionblog_photo_12_31_15 test. When you have a general vision test, one of the main conditions the eye care practitioner is checking for is a refractive error. A refractive error means there is an abnormality in the shape of the eye, changing the eye’s ability to focus light directly onto the retina.This causes blurred vision and can usually be corrected by wearing prescription eyeglasses, contact lenses and possibly, alternate treatments such as vision therapy, ortho-k, LASIK or refractive surgery such as LASIK.

The term, “refractive error” refers to a problem with the process of refraction that is responsible for sight. Normally, light rays that enter your eye are refracted or bent through the cornea and the lens, and ultimately converge or are focused onto a single point on the retina. From the retina, messages are sent through the optic nerve to the brain which then interprets these signals into the image that we are seeing.

In order for this process to work effectively, the anatomy of the eye including the length of the eye and the curvature of the cornea and the lens must be just right to be able to focus the light onto the retina. When this is not the case, a refractive error will occur.

There are several different types of refractive errors, depending on which part of the eye is affected, and it is possible to have multiple refractive errors at the same time:

Myopia or nearsightedness:
In myopia the length of the eyeball is too long which results in light coming to a focus in front of the retina, rather than on the retina. This allows the individual to see well when objects are close but not clearly when looking at objects at a distance.

Hyperopia or farsightedness:
Hyperopia is when the eyeball is shorter than normal and can result in near objects being blurry. However, people experience hyperopia differently. Sometimes distant objects are clear while other times people may experience overall blurred vision near and far or no problems at all. In children particularly, the lens may accommodate for the error allowing for clear vision but may cause fatigue and sometimes crossed eyes or strabismus. Hyperopia causes eyestrain or fatigue especially when looking at near objects for a period of time. Often people with 20/20 vision may still need glasses at their desk to relax their eyes and improve concentration.

Astigmatism:
Astigmatism is usually the result of an irregularly shaped cornea (although it can sometimes also be due to a misshapen lens). The cornea, which is normally round, is more football-shaped in an eye with astigmatism, resulting in multiple focus points either in front of the retina or behind it (or both). People with astigmatism usually have blurred or distorted vision to some degree at all distances, near and far.

Presbyopia:
Presbyopia is an age-related condition which usually begins to appear sometime after 40. As the eye begins to age, the lens stiffens and can no longer focus clearly on objects that are close.

It’s important to note that presbyopia is often confused with hyperopia, as both cause problems focusing at near distances. However, high hyperopia can also cause blur at far distances as well, especially in dim lighting, and depth perception problems can result in motor vehicle accidents. In these instances people with hyperopia could use glasses at any distance.
If you are having trouble seeing, it is important to have an eye exam to determine the cause of the problem and to effectively correct your vision. Even if your vision is fine, you should schedule a routine eye exam on a regular basis to ensure that your eyes are healthy and that any potential problems are caught early.

How Do We See?

eyeball drawingHave you ever thought about how vision works? Seeing is an incredible gift made possible by a system in which the eye and the brain process visual information from the outside world. If any step of that process does not function properly, vision will be impaired.

Similar to a camera, the eye transmits light from the world around us into an image that we can perceive. Certain parts of the eye even function like the different parts of a camera such as the shutter, the lens and film (if we can hearken back to the days when we used film in cameras). Here is a quick breakdown of the fascinating way our eyes and brain enable us to see and experience the world around us:

The Vision Process

Light reflected from an object in our field of view is gathered by the cornea which is essentially the clear “window” to our eye. The cornea then refracts the light rays through the pupil (the center of the iris where light enters the eye). The iris, which like the shutter of a camera will enlarge and shrink based on how much light is coming in, then passes the image onto the crystalline lens. Just like a camera lens, the lens in the eye focuses the light rays, projecting them to a point at the back of the eye called the retina, where the image will appear upside down. The retina contains a thin layer of color-sensitive cells called rods and cones that perceive color.

From the retina, the visual signals travel to the brain via the optic nerve. The brain receives information from both eyes and must then converge the images (and flip them right side up) to get a complete picture.

Vision Problems

A breakdown in vision can happen at any point in this process. From the muscles that control the eyes, to the parts within the eye, to the pathway to the brain. Sometimes vision impairment is due to technical problems with the eye receiving the information and passing the signal on, such as convergence insufficiency (inability to coordinate the eyes to converge on one point), myopia (nearsightedness) or cataracts (clouding of the lens).

Other times, the eyes might work perfectly, but there is a problem with the brain interpreting the signals it receives. In these cases we can’t “see” in the traditional sense, because our brains aren’t able to properly “read’ the signals or we don’t know what we are looking at. This is the case for some learning disorders that are caused by the visual processes in the brain such as dyslexia.

As you can see, vision is quite a complicated process. A simple vision exam isn’t always able to determine vision problems, especially in children which is why it is so important to have regular comprehensive eye exams, to measure the health of the eye and all of its parts.

6 Common Eye Myths Debunked

girl 20with 20alphabetOver the centuries there have been a lot of old-wives tales circulating about eyes and vision. You know, like the one that if someone hits you on the back while your eyes are crossed they will stay that way. Unlike this example, some of these myths do have roots in truth, yet filtering out those truths isn’t an easy task.

Here are a few of the most common myths and truths about the eyes and vision.

  1. Myth: Eating a lot of carrots will help you see in the dark.

    Truth: Carrots have a lot of Vitamin A, a vitamin that is essential for good eyesight, but eating a lot of carrots isn’t going to give you 20/20 vision or help you see in the dark. Likely, the basis of this over-exaggeration is that night-blindness and vision loss found in underdeveloped countries can be a sign of malnutrition due to Vitamin A deficiency. However, you only need a relatively small amount of Vitamin A for vision, and it is easily obtainable in a normal balanced diet from a lot of sources, not limited to carrots.

    Higher-than-normal doses of Vitamin A might be useful in treating certain eye conditions and as part of a combination of vitamins used to slow the progression of early-stage macular degeneration. However, in any of these cases, do not take Vitamin A supplements without instructions from your eye doctor.

  2. Myth: Wearing glasses makes your vision worse.

    Truth
    : People think this is true because often once we start wearing glasses our vision continues to deteriorate and we have to keep going back for a higher prescription. The notion that wearing glassescauses your vision to get worse is simply not true. Distance vision or myopia typically gets worse over time, especially during childhood and adolescence, and does depend on whether the child wears glasses. Additionally, most people begin to experience vision deterioration as they enter their 40’s and 50’s with or without the use of vision correction devices.
  3. Myth: Sitting too close to the TV is bad for your eyes.

    Truth
    : While it may cause your eyes to feel tired, there is no evidence that sitting too close to the TV will harm your eyes or vision. Children in fact have a heightened ability to focus on close objects so often it is natural and relatively comfortable for them to sit close to a screen.
  4. Myth: Reading in dim light can damage your eyes.

    Truth
    : This one also has no good evidence. While yes, your eyes are working harder and may feel tired when reading in dim light, there is no evidence of permanent or long-term damage to your eyes.
  5. Myth: As you get older there is nothing you can do to prevent vision loss.

    Truth
    : While most older adults will eventually develop some degree of presbyopia which is near-vision loss, and eventually cataracts, no sign of vision loss should be ignored. Vision problems like these can be treated, allowing you to see clearly again. Moreover, there are many serious eye diseases such as glaucoma and macular degeneration that can threaten your vision and eyes with permanent and severe vision loss if not diagnosed and treated early. If you are 40 or older, you should have your eyes checked with a comprehensive eye exam on a yearly basis. In many cases, early treatment can save your eyesight.
  6. Myth: Squinting causes vision loss.

    Truth
    : Squinting is a natural reaction of your eyes to let less light into the pupil in order to sharpen your focus. Rather than impairing your vision, squinting is usually a sign that someone can’t see clearly which often suggests that their vision is impaired and that they need glasses to see better in the first place.
