Research indicates that UV light can harm the eye's lens and retina with extensive low dosage exposure. One possible outcome of UV exposure is the formatin of cataracts. Some research also suggests that long-term exposure to blue light may lead to certain eye disorders.

UV-blocking lenses are not only recommended for people involved in outdoor activities, but for those taking photosensitizing medications, people exposed to artificial UV light in the work place, and people recovering from cataract surgery.

Lenses that block blue light reduce glare, ease eyestrain, sharpen definition, and improve depth of field. Blue light blocking lenses are especially popular with golfers and skiers, because they make contours on putting greens and slopes easier to see. Some people report that blue light blocking lenses help reduce eye fatigue under fluorescent lights and in front of computer screens. By cutting down on blue light exposure during the day, night vision can improve by upt to fifty percent.

The effects of the sun on your eyes are nothing to take lightly, but with all the choices available in UV and blue light blocking lenses, there's no reason why you can't protect your eyes and enjoy the healthful benefits of sunny day.
