The Delta is a sleek full-frame sunglass featuring polarized lenses with a super-hydrophobic coating. The polarized lenses reduce glare & improve clarity while the super-hydrophobic coating prevents water from clinging to the lens. Water instead clings to itself and beads off. Super-hydrophobic coatings are also anti-static preventing dust & dirt from sticking to the lenses. The lenses are scratch resistant and have 100% UVA/UVB protection. These pairs have black frames with smoke/yellow/blue lenses. Epoch Eyewear is a Veteran owned and operated company.
