Protect Your Eyes From The Sun
Many people are cheered by a bright, sunny day, but the effect of all that sunlight on the eyes is a less sunny proposition. Glare and UV radiation can create a variety of issues, from stressful driving that threaten your safety to macular degeneration and early cataract. At Yorba Linda Optometry and Beyond, we help you select the right sunglasses.
All Sunglasses are not the same! 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. Many off the shelf sunglasses claim 100% UV protection but few protect against UVB rays.
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 cause retinal damage such as macular degeneration which is a serious irreversible condition making 20/20 eyesight impossible.
What types of glasses can I choose from? A second pair of prescription sunglasses is your best protection but you can also choose Transition Lenses which go from light to dark when you step outside. Many of our patients love XtrActive Transition Lenses which get dark behind the windshield of a car and provide variable darkness based on outdoor brightness.
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 great for tasks such as boating, fishing, skiing, golfing, jogging, and driving.
What additional types of protection should I consider? UV-blocking contact lenses. Swim goggles.
