The Epoch Link is the first of many original designs from Epoch Eyewear. The frame includes the most overall inlayed rubber of any of our styles to ensure a perfect fit and durability. These features make this our favorite new style for 2017. 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.
