What Are UV400 Sunglasses and Why Do I Need Them?
Everyone is familiar with polarized sunglasses. It's a key marketing message for most eyewear retailers out there, and allows them to charge a premium. However, there is a major misconception, as the general public thinks that polarized lenses are the key to shielding their eyes from the sun's harmful UV rays. This is simply not the case. In fact, polarized lenses do nothing to prevent the absorption of UV rays. Sure, they absolutely reduce both sun glare and strain on the eyes which makes for a much more pleasant "viewing experience" of our big and beautiful world. However, they don't protect your eyes from UVA and UVB rays.
Mind blown? You're not alone.
