Is your favorite pair of sunglasses providing optimal protection from ultraviolet (UV) rays? Overexposure to these rays can cause eye and vision problems, according to the American Optometric Association (AOA). Before spending time outdoors this summer, be sure your sunglasses are adequately protecting your eyes with these tips.
• Sunglasses should block out 99-100 percent of both UV-A and UV-B rays. While some contact lenses also offer UV protection, these should be worn with sunglasses to maximize protection.
• Your sunglasses should screen out 75-90 percent of visible light.
• The frame of your sunglasses needs to fit close to your eyes and contour to the shape of your face. This prevents exposure to UV rays from all sides, even from behind.
• Pick lenses that are perfectly matched in color and are free of distortion and imperfection.
• Lenses should also have a uniform tint, not darker in one area from another. A gray tint, w is particularly helpful when driving as it offers the best color recognition.
• To really be sure your sunglasses will properly protect your eyes from UV radiation, your best resource is your optometrist, who will also help ensure your eyes are healthy through yearly, comprehensive eye exams.
