Reasons to Wear Sunglasses

Sunglasses

UV Protection

 The sun's UV radiation can cause cataracts; benign growths on the eye's surface; and photo keratitis, sometimes called snow blindness, which is temporary but painful sunburn of the eye's surface. Wide-brimmed hats and caps can block about 50 percent of UV radiation from the eyes but that is not enough protection.

Blue-Light Protection

Long-term exposure to the blue and violet portion of the solar spectrum has been implicated as a risk factor for macular degeneration, especially for individuals that are “sun sensitive.”

Comfortable vision

The sun's brightness and glare interferes with comfortable vision and the ability to see clearly by causing people to squint and the eyes to water.

Dark adaptation

Spending just two or three hours in bright sunlight can hamper the eyes' ability to adapt quickly to nighttime or indoor light levels. This can make driving at night after spending a day in the sun more hazardous.

Skin Cancer

Cancer of the eyelids and skin around the eyes is more common than people think. People should wear sunglasses outdoors whether they are working, driving, participating in sports, taking a walk, running errands or doing anything in the sun.
