Uv 400 Sunglasses: The Ultimate Eye Protection**
Uv 400 sunglasses are a popular choice for those who want to protect their eyes from the harmful effects of ultraviolet (UV) radiation. These sunglasses are designed to block UV rays up to 400 nanometers in length, which is the most effective way to prevent potential damage to the eyes and skin.

UV 400 sunglasses use a special coating to block UV rays from reaching the eyes. This coating is often made of polarized materials, which help to reduce glare and improve clarity of vision. While not all UV 400 sunglasses include polarized lenses, they all provide 100% UV protection, which is the highest level of protection available.
