Sunglasses

Many people are cheered by a bright, sunny day, but the effect of all that sunlight on the eyes is a less sunny proposition. UV and glare can create a variety of issues, from dangerous "snowblindness" to irreversible disorders that threaten your eyesight. Here are some frequently asked questions about the role of sunglasses in protecting the eyes from harm. If you want to know more about choosing the right sunglasses, call Dr. Morer at 561-963-0099 today.

What are UV rays? UV stands for ultraviolet, a band of spectrum invisible to the eye. Ultraviolet light consists of UVA, UVB, and UVC rays. UVC rays are stopped in Earth's atmosphere before they reach the eye, but UVA and UVB can both reach the eye and potentially damage it.

How does UV affect unprotected eyes? UV rays can cause proteins inside the lens to become opaque or cloudy, a condition known as cataracts. Cataracts can interfere with night vision, reduce your ability to see colors, and make reading difficult; they cannot be reversed, only removed. UV exposure can also cause retinal damage, changes in the eye tissues, and a temporary but irritating "sunburn" of the cornea called photokeratitis.

How do I know my glasses will protect my eyes? Choose glasses that claim to block at least 99 percent of UV rays -- UVA as well as UVB. Look for label reading "UV 400," since this designation means that the glasses block UV rays as small as 400 nanometers, providing 100 percent eye protection. Of course you need to protect your eyes from the glare caused by the visible spectrum as well. To accomplish this, select products that block 75 to 90 percent of visible light.

What are polarized lenses? Polarized lenses are specially designed to filter out certain types of glare that tend to radiate upward from horizontal surfaces when sunlight bounces off of these surfaces. They are recommended for tasks such as boating, fishing, skiing, golfing, jogging, and driving.

What types of glasses can I choose from? We are able to produce your prescription into most sunglass frames. We offer wrap styles in both metal and plastic. We have eyeglasses with magnetic polarized clip-ons. Whether it's for distance vision only, bifocals, or progressive lenses we have what your eyes need and want for sun protection.

What additional types of protection should I consider? If you worry about light, including harmful UV, leaking in through sides or top of your sunglasses, wear a broad-brimmed hat to reduce some of this exposure. If you use prescription eyewear to correct your eyesight, you may also want to think about getting a pair of UV-blocking contact lenses in your prescription. Here at Crystal Clear Optical we strongly recommend polarized and no-glare lenses. They are available in gray and brown amber. We are experts in discussing the proper sun lens for you.
