100% UV PROTECTION: Always wear sunglasses with 100% UV protection. Sometimes you will see “UV400 protection” which means the lenses will block UV light up to 400 nanometers (all UVA & UVB rays) on the UV spectrum. Prolonged exposure to the sun’s harmful UV rays can cause cataracts, pterygium and corneal sunburn.
FLEXIBLE SPRING HINGES: Tired of sunglasses that pinch your temples or get bent out of shape and fall of your head? These sunglasses feature a flexible spring hinge that flexes to fit your head and springs back to its original size.
