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 our office at 818-982-0076 today.

What are UV rays? UV stands for ultraviolet, a band of light in the invisible spectrum to the eye. Ultraviolet light consists of UVA, UVB, and UVC rays. All of these high-energy forms of light can reach the eye and cause potential macular damage, which can affect your vision.

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; it 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? Prescription sunglasses are designed to absorb and block UV light. Sunglasses marked UV-400 cover all UVA and UVB rays. The average pair of sunglasses bought over the counter usually is not equipped with optically correct lenses; therefore they will not be useful in blocking out UV light. Our practice carries only the top brands of UV blocking sunglasses.

What are polarized lenses? Polarized lenses are designed to block light at a certain angle. When light is reflected off a surface it comes in at 360°. Polarized lenses come in at 180° to block light and reduce glare. 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 provide you with a wide range of sunglass options. The best option for proper sun protection is a properly fitted pair of prescription sunglasses. If you do not wear prescriptions sunglasses then quality made ground optical lenses with the proper tinting to protect eyes from light is another great option. Make an appointment with our office today for more information by calling us at 818-982-0076.
