The Epoch 4 is ultra sporty and available in a variety of bold colors. The arms feature co-injected inlaid rubber providing all day comfort with a non-slip fit. All lenses are shatterproof polycarbonate and block 100% of UV rays. 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 benefit 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.
