Sunglasses!
Sunglasses are an essential part of keeping your eyes healthy and maintaining good vision. There are many ocular conditions that are a direct result of too much exposure to UV light. Conditions such as cataracts, macular degeneration, pingueculae and pterygia can develop and progress with exposure to the harmful UV rays. And these effects are cumulative over a lifespan. Protecting your eyesight now is crucial.
Choose sunglasses that are labeled with a UVA/UVB rating of 100% to provide the most UV protection. Do not mistake dark-tinted sunglasses as having more UV protection. The darkness of the lens does not indicate its ability to shield your eyes from UV rays. Many sunglasses with light-colored tints, such as green, amber, red, and gray offer the same UV protection as very dark lenses.
Large, wraparound-style frames may provide more efficient UV protection because they cover the entire eye-socket. They will also protect the delicate skin around the eyes from certain skin cancers. This is important when doing activities around or on water because much of the UV comes from light reflected off the water’s surface.
Polarized sunglasses, which contain a special filter to eliminate glare, are ideal for dealing with reflective glare conditions. When light strikes a surface, the reflected waves are polarized to match the angle of that surface. So, a highly reflective horizontal surface, such as a lake, will produce a lot of horizontally polarized light. Therefore, the polarized lenses in sunglasses are fixed at an angle that only allows vertically polarized light to enter. This provides increased comfort and visibility, not only for activities around water but for driving, biking, jogging, skiing and most outdoor activities.
