The Delta 2.0 is a sleek full-frame sunglass featuring polarized lenses with a super-hydrophobic coating. The Epoch logo embossed nose piece is inlaid rubber for a no slip fit. The frame includes embossed Epoch accents on the nose bridge and arm tips. The lenses are scratch resistant and have 100% UVA/UVB protection. Tons of functionality with looks to match. 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. We are proud to be a part of the Veteran community and build a company that provides jobs and great products.
