The Twilight lens system blocks 100% of harmful UV light and 60% or more of harmful High Energy Visible (HEV) blue light while providing 93% overall visible light transmission. The unique filtering properties of these HEV filters effectively reduce scattered blue light and improve contrast without compromising overall light transmission. The lens system is protected by a one-year scratch resistance warranty and includes an anti-reflective coating to minimize glare and halos created by artificial light sources. The patented frames feature Flex2Fit adjustable temples and a unique Soft Touch finish to enhance comfort during extended wear. The adjustable system enables the wearer to manually contour the temples for a personalized fit that is extremely secure with a minimal amount of pressure. All Cocoons fitovers feature a limited lifetime warranty and include a custom designed case and lens cloth.
