ARE WHY SUNGLASSES ARE VERY IMPORTANT?
Sunglasses aren't just a fun summer accessory; they're also a necessary prescription for good eye health. Long-term sun exposure without proper protection can increase the risk of eye disease, such as cataracts, eye growths, and eye cancer.
Even short-term exposure can damage the eyes. Sun reflecting off water can cause a painful sunburn called photokeratitis on the front part of the eye. It causes redness, blurry vision, sensitivity to bright light, and, in rare cases, even temporary vision loss.
“Think of sunglasses as sunscreen for your eyes,”. “Your eyes need protection from the sun’s damaging ultraviolet rays just like your skin.
Make sure your eyes are protected year-round. Harmful UV rays are present even on cloudy days.”
