The American Optometric Association recommends wearing sunglasses that block ultraviolet radiation (UV) whenever a person is in the sunlight to protect the eyes from UV and blue light, which can cause several serious eye problems. Since the 1930s, sunglasses have been a popular fashion accessory, especially on the beach. In the early 20th century, they were also known as sun cheaters ( cheaters then being an American slang term for glasses). They can sometimes also function as a visual aid, as variously termed spectacles or glasses exist, featuring lenses that are colored, polarized or darkened. Sunglasses or sun glasses (informally called shades or sunnies more names below) are a form of protective eyewear designed primarily to prevent bright sunlight and high-energy visible light from damaging or discomforting the eyes. Kids wearing sunglasses is an important thing.Wearing sunglasses under direct sunlight: Large lenses offer good protection, but broad temple arms are also needed against "stray light" from the sides. “As a parent, you should be aware that start accumulating that sun damage just as soon as there’s exposure. “Whenever you’re thinking, ‘Hmmm, I should be using sunscreen,’ you should be wearing sunglasses,” too, Bishop says. And be sure they wear them, sunny or not.Ī 2014 survey by the American Academy of Ophthalmology found that only 32% of parents make their kids wear sunglasses that are rated to block UV light. When you pick out your new shades, remember this: Get some for the kids you know. But a higher price tag doesn’t always equal great image quality, he adds. “If you’re stopping by the gas station on the way to the lake to pick up sunglasses, you’re more likely to have something of lesser quality,” Horn says. Some lenses, especially the more curved ones, can cause distortion. How well they help you see matters a lot, too. What’s best: Shatterproof glass? Plastic? Some newfangled polycarbonate material? Again, it’s a matter of taste. If your sunglasses aren’t rated to block UV rays, you might let even more into the back of your eye. When you wear darkened lenses, the pupil opens more to let in more light. Your pupil, the black dot at the center of your eye, controls how much light gets in. Just because a lens is almost black doesn’t mean it blocks UV rays. But they can make it harder to see things like computer screens, smartphones, or dashboards. You might see better through them when there’s tons of light around. But they don’t take the place of UV protection. These reduce glare at the beach, in the snow, or out on the water. Those things aren’t good for your eyes, either. They can also keep out sand and allergens. Sunglasses that wrap around your eyes can help block stray UV light.

It may not lead to cancer in your eyes, but it can thicken tissues around them and cause discomfort. ![]() UV light can cause changes in cells that lead to skin cancer, Bishop says. It could even cause tissue to grow over your eyeball. ![]() It can also destroy the retina, the lining at the back of your eyes that helps you see clearly. “It’s not too much to expect your glasses to do that.” “You want both of those blocked 99 to 100%,” says eye doctor Rachel Bishop, MD. Do these glasses block 100% of both UVA and UVB rays? If not, leave them on the rack. It can also damage your eyes.īefore you even check the price tag, read the label. But too much of it can cause problems like sunburn and skin cancer. The sun gives off UV radiation that you can’t see or feel. And buy some for the kids in your life, too.įollow these rules to pick a pair that look good and protect your peepers. So grab those shades before you head for the beach, or the park, or anywhere outside - whether it’s bright or cloudy. You'll protect the whites of your eyes from damage and block that eyeball-searing ultraviolet (UV) light. It matters for a lot of reasons.įirst, you'll ward off those little wrinkles at the corners of your eyes.
