Eye protection from the sun with sunglasses

Protect your eyes with sunglasses
To protect your eyes from harmful solar radiation, sunglasses should block 100 percent of UV rays. Just as the sun’s ultraviolet (UV) rays can damage skin, they can also harm the lens and cornea of the eyes.

UV radiation increases your odds of getting cataracts, which cloud the eye’s lens and lead to diminished eyesight. It has also been linked to macular degeneration, a treatable, but an incurable disease of the macula, a part of the retina that is essential for sharp vision.

Long-term exposure to UV radiation can lead to cataracts, skin cancer around the eyelids, and other eye disorders. In the short term, excessive exposure to UV radiation from daily activities, including reflections off of snow, pavement, and other surfaces, can burn the front surface of the eye, similar to a sunburn on the skin.

Frames with a close-fitting wraparound style provide the best protection because they limit how much stray sunlight reaches your eyes from above and beyond the periphery of your sunglass lenses.

Be sure to select sunglasses that block UV rays. Don't be deceived by color or cost. The ability to block UV light is not dependent on the price tag or how dark the sunglass lenses are.

Wear gray-colored lenses because they reduce light intensity without altering the color of objects, providing the most natural color vision. Lens color is really a matter of preference the most important feature to look for in a sunglass lens is how much UV radiation it absorbs.

Do not forget protection for children and teenagers. They typically spend more time in the sun than adults. Children's sunglasses now come in an array of colorful designs, many modeled after adult styles.
