Comfort is the key with the Native Eyewear Perazzo Sunglasses. The Rhyno-Tuff Air frames are extremely lightweight, yet durable enough to withstand high velocity collisions and extreme temperatures, creating a comfortable feel with the strength you require. The Cam-Action hinges help the temples lock into place quickly, for easy on/off access. N3 polarized lenses pass Z87.1 testing and feature up to 40% IR reduction, UV protection up to 400nm, and state-of-the-art blue light filtering. These high-quality, impact-resistant lenses block 100% of the harmful UV light and eliminate glare for sharp, clear vision with increased contrast and depth perception. Cushionol nose pads allow you to wear these all day long without any pain or discomfort.
