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. Mirror lenses are constructed by applying a reflective coating to a smoke lens base. These unique products deliver the same protection as smoke lenses but have the added benefits of enhanced color perception while reducing glare -- all due to the addition of the color reflective coating. Ideal for full-sunlight, snow, and water-reflective conditions. Light transmission 10-13% depending on reflective coating applied. Epoch Eyewear is a Veteran owned and operated company.
