Quality sunglasses can protect your eyes from UV rays and glare that can create a variety of issues, from dangerous "snowblindness" to irreversible disorders that can threaten your eyesight. Brands often featured at our store location include the following
What are UV rays?
- UV stands for ultraviolet, a band of the light spectrum invisible to the naked 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.
- UV rays can cause proteins inside the eye’s 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 ray exposure can also cause retinal damage, changes in the eye tissues, and a temporary but irritating "sunburn" of the cornea called photokeratitis.
- Choose glasses that claim to block at least 99% of UV rays; UVA as well as UVB. Look for a label stating "UV 400," since this designation means that the glasses block UV rays as small as 400 nanometers, providing 100 percent eye protection.
- 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 outdoor activities such as driving, boating, fishing, skiing, golfing, and jogging.
- If you normally wear glasses to correct your eyesight, you may be happy with a non-prescription pair of clip-ons or wraparound sunglasses that simply fit over your regular lenses. If you'd rather not wear that much on your head all at once, you can order a pair of prescription sunglasses or you can order glasses that darken when exposed to bright light.
