Stylish Sunglasses with UV400 Protection

Are your eyes being protected every time you step out into the sunshine? We’re serious about great-looking sunglasses here at Knockaround, but we’re also serious about keeping your eyes safe. That’s why all of our sunglasses—from classic tortoise shell Premiums to sleek neon Fast Lanes—come with UV400 lenses. Even our polarized, Blue Light Blocker, and CUSTOM Shop lenses have UV400 protection built into every pair.

How do UV400 sunglasses work? Think of these specs as sunscreen for your eyes. UV400 lenses are designed to block 99% to 100% of UV light—you know, the harmful rays that can damage your skin and eyes when you spend too much time in the sun. The UV protection is incorporated directly into the lens, so it will last as long as your sunglasses do (and that’s a long time, especially with extra-sturdy frames like our Fort Knocks!).

We take sun protection seriously because extended exposure to UV rays can cause unwelcome side effects including eye pain, redness, blurry vision, and irritation. It’s especially important to wear sunglasses with UV protection if your hobbies include lots of sun, snow, or water—think surfing, climbing, skiing, and hiking.

When you’re picking out a pair of UV400 sunnies for yourself, don’t forget to grab matching kids sunglasses for your little ones. Typically, more UV exposure happens before age 20 than at any other point in our lives, so UV protection is especially important for the kiddos. Our tough, impact resistant styles for kids ages 1 to 5 years come in bright colors they’ll love, too.
