Prescription Sunglasses and UV Protection Sunglasses

Sunglasses. The Smart Look.

Sunglasses - with or without a prescription - that can block out nearly all UV rays are now readily available, protecting the eyes and significantly reducing the risk of vision problems caused by sunlight. Lenses should be gray, green or brown and the larger the lenses, the better. Wrap-around sunglasses provide an extra measure of protection, as does wearing a hat with a wide brim. Contact lens wearers can get lenses that filter out a lot of UV radiation. While these lenses should not be used in place of sunglasses, they do help screen out light that comes in around the top and sides of glasses.

What to look for in shades

Look for sunglasses that block at least 99% of ultraviolet rays. UV protection is a concern for all of us. People at high risk for developing problems from UV exposure include those who spend long hours in the sun because of work or recreation, those who have had cataract and refractive surgery, individuals who have certain retinal disorders and people who take certain medications - such as tetracycline, sulfa drugs, birth control pills, diuretics and tranquilizers - that increase the eye's sensitivity to light. And children's eyes are particularly susceptible because kids usually spend more time outdoors than adults and their young eyes let more UV rays inside.

The best sunglasses are those purchased from an optometrist. This ensures the sunglasses have the appropriate amounts of UV filtering and are the best protection for your eyes while in the sun. Buying sunglasses from street vendors is risky. There's no assurance that the eyewear, no matter how dark the lens, will protect against UV rays. An Optometrist or Optician will be able to answer your questions about UV protection, provide you with the widest available options, and be sure that you'll be getting the best protection for your eyes.
