Randolph Eyewear makes the best glasses in the USA. Polarized and Non-Polarized lens options.

Facts about Polarized Sunglasses and Exposure to UV Rays

Proper sun protection for your eyes:
  • Not all sunglasses block 100 percent of UV rays. The lens material and coatings applied to the lens determine the amount of UV protection sunglasses provide, not the color and darkness of a sunglass tint. Polycarbonate plastic sunglass lenses absorb essentially all UV radiation, with the added advantage of extreme impact resistance.
  • Different tints can help you see better in certain conditions and reduce glare and reflections by changing the quantity and quality of light entering the eye, but the color and darkness the tint of the sunglasses lens do not necessarily indicate the UV protection provided.
  • Wear sunglasses even when you're in the shade. Your eyes will still be exposed to UV rays reflected from water, pavement, snow, sand, windshields and other surfaces.
  • Wear sunglasses in winter. Snow reflects more UV rays than most other surfaces. Take care of your eyes when you ski, snowboard, snow-shoe, snowmobile, shovel or any other outdoor winter activity.
  • UV light can go right through clouds even when it is overcast.
  • The sun's rays are strongest between 10 am and 2 pm so be sure to wear proper sunglasses especially during those hours.
  • UV can reach the eyes from the sides and top of sunglasses, even with lenses that absorb all UV radiation. Polarized sunglasses with large, wrap-around style, sport wrap frames are good for peripheral protection.

Advantages of Polarized Sunglasses

Good quality, proper fitting, UV-protective sunglasses with polarized lenses in combination with other features can enhance your outdoor activities and sport experiences, whether you enjoy boating, fishing, in-line skating, mountain biking, skiing, hiking, kayaking, waterskiing, jet skiing, windsurfing, sailing, driving or just relaxing.
Too much unprotected exposure to UV radiation can cause “photokeratitis” – a sunburn of the eye. The symptoms are temporary eye redness,uncomfortableness, light sensitivity and tearfulness. Fortunately, these symptoms are usually short-lived, although long periods of UV radiation exposure can sometimes cause permanent eye damage. "Snow blindness" is the common term for severe photokeratitis, which causes temporary vision loss usually lasting 24-48 hours.
