Choosing prescription sunglasses is a little trickier than picking out a regular pair of eyeglasses. Since the sunglasses are inherently darker, it's more difficult to see yourself in the mirror after putting them on. You can rely on a friend's judgment, but sometimes they might not know the look you're going for. Here are a few basic guidelines to remember when choosing prescription sunglasses.

Leber's congenital amaurosis is an inherited eye condition that causes very low vision. Here are three things parents need to know about it.
What are the signs of Leber's congenital amaurosis?
The signs of this condition usually appear within a child's first year of life. You may notice that your child is rubbing or pressing on their eyes. Their pupils may respond slowly—or not at all—to changes in light conditions. Rapid, involuntary eye movements, known as nystagmus, can also be present.
Childhood vision problems are difficult for parents to detect without understanding exactly what they're looking for. After all, if you ask a child if they're having trouble seeing something, they won't necessarily know that they are since their vision is all they've ever known. Without a point of reference to compare it to, kids won't even realize that they're actually experiencing a problem. Here are some things to watch for that may mean your kiddo is struggling to see.

A day in the sunshine can burn your eyes as well as your skin. If you return home after a day outside and your eyes are red, itchy, or tearing and if looking at shiny things bothers you, your eyes have probably been burned by the sun's ultraviolet rays. A light case of sunburn shouldn't cause any lasting damage to your eyes, but if you repeatedly burn them, medical issues like cataracts, cancer, and photokeratitis (photokeratitis can cause temporary blindness) can eventually develop in your eyes.
