Why Sunglasses are usually Black?
“One of the biggest misconceptions I hear is that people think their eyes are protected by wearing very dark sunglasses. Nothing can be further from the truth. The tint of the lens has absolutely nothing to do with the amount of ultraviolet protection the lens provides,” says Dr. Werner.But darker doesn’t mean better protection. When considering a pair of dark sunglasses, ophthalmologist Marc Werner.While wearing any sunglasses without UV protection is risky, dark shades are actually the riskiest. “Dark sunglasses that don’t protect from UV rays are even more dangerous, because the dark lenses cause the pupil to enlarge, allowing even more UV light to enter the eye where it can lead to significant problems, such as macular degeneration,” he explains. To find shades that look great and keep your eyes safe, Werner says it’s important to choose a pair—clear or tinted—that protect against both UVA and UVB rays so you’re blocking 100 percent of ultraviolet light.
