Debunking eye myths

BC news reports on eye myths. The article debunks 11 common eye myths. Here's a short summary of the myths discussed in this article.

Myth: Squinting a lot damages your vision.
The truth is squinting may mean you need glasses but it will not increase your need for spectacle correction.

Myth: Reading in poor light will harm your vision.
It may be harder to read in dim light but is is no worse than taking a picture in dim light damages a camera.

Myth: Sitting too close to the TV is bad for you eyes.
Sitting close to your computer may contribute to dry eyes which can cause temporary problems but not permanent damage.

Myth: We will have the same eye problems as our parents.
Many vision problems have a genetic component but that only increases your risk. It does not guarantee the same problems.

Myth: There's nothing you can do about your vision getting worse as you get older.
Though cataracts is a part of the aging process there are many things you can do about preventing cataracts such as a balanced diet or avoiding cigarettes. 

Myth: Eating carrots will improve your vision.
Vitamin A deficiency may cause a decrease in vision but such is rare in the United States. If you have  enough vitamin A in your system then eating more carrots will not enhance your vision.

Myth: Eye exercised can improve your vision.
Eye exercises to eliminate glasses or prevent presbyopia (short arm syndrome) have no merit. However, vision therapy, a series of exercises design to help focusing or eye alignment issues have shown great success. Clear View can help determine if vision therapy is beneficial for your child.

Myth: Using glasses over a long period of time will cause vision to deteriorate, causing dependence on glasses.
Wearing glasses constantly does not change your eye to create a dependence on them. Nevertheless, enjoying clear vision may become so enjoyable  that you do want to wear your glasses constantly.

Myth: Not wearing your glasses will cause your vision to get worse, faster.
It  may cause eye strain but it will not change your prescription.

Myth: Children will outgrow a crossed eye without intervention.
Children who have crossed eyes should see the eye doctor. Many of the causes of a crossed eye or strabismus can be treated and are best treated as early as possible. Effects on vision development are drastic and better handled when diagnosed at an early age.

Myth: It's OK to skip my child's first eye exam if they don't seem to have any problems
There are many vision problems in children that are not easily identified without a qualified physician. For instance amblyopia, where one eye doesn't see as well, can be masked by the fact that we have two eyes to work with. A proper evaluation at 9 months and again at 3 and 5 years are essential to intervening to identify issues that can be vision threatening or worse.
