The Epoch 7 is one of our best selling styles. Featuring a matte finish and an open frame, the 7 is quickly becoming a favorite among athletes everywhere. The lenses are shatterproof polycarbonate and 100% UVA & UVB protective. The lightweight frame features inlaid rubber for comfort and durability. 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.
