Eye Facts: See Through the Common Myths

Posted on 2013/06/18 at 2:29 pm by LASIK MD

Despite the incredible advances in science that have helped doctors understand eye vision better than ever, numerous myths remain that some people take as “eye facts.” Here are four common myths associated with the eyes and why they are not true.

Myth: Frequent Squinting Damages Your Vision

While squinting frequently may be a sign that you need vision correction, it is not going to make your vision any worse. The scientific reason we squint is to make the pupil smaller to allow less light to come into the eye. By closing your lids together, it enhances your focus. There can be side effects from squinting too much, though, including headaches from contracting the muscles in your face, but that won’t damage your vision either.

Myth: Reading in the Dark is Bad for Your Eyes

Reading in the dark or in low light conditions is obviously more difficult than in bright light, but doing so will not cause any permanent damage to your vision. In low light, your pupil is enlarged to allow more light into the eye. A wider pupil is not more susceptible to damage than a small pupil that reduces the light that enters the eye.

Myth: You Shouldn’t Sit Too Close to the TV or Computer Screen

If you were like most kids, you’ve heard your mom scream, “Don’t sit so close to the TV, it’s bad for your eyes!” Sadly for Mom, this is not true. While staring closely at televisions, computer monitors, and mobile devices can make your eyes tired, it will not do any permanent damage. Still, it’s important to take breaks from staring at your television or computer screen to avoid dry eye symptoms or headaches.

Myth: Wearing the Wrong Kind of Prescription Glasses Will Cause Damage to Your Eyes

Eyeglasses are implements prescribed to sharpen your vision. While the correct prescription eyeglasses will help you to see more clearly should you need them, wearing a pair of your grandfather’s inch-thick bifocals will not physically damage your eyes. However, there is the caveat that children eight years old or younger who need eyeglasses should wear their own prescription glasses so they may avoid the possibility of developing amblyopia, or “lazy eye.”

Of course, one of the best ways to avoid falling for these eye facts is to undergo a safe, easy and effective LASIK vision correction procedure from a highly reputable provider. And that’s no myth!
