Formerly Epoch 3, the Liberator is named in honor of "the bike that won the war." Liberator is a stylish and sporty full frame sunglass. The arm is built with co-injected inlaid rubber making it ultra comfortable. Liberator is available with amber, smoke, clear, yellow, blue mirror and red mirror lenses, all of which are shatterproof polycarbonate and block 100% of UV rays. This style has been a favorite for golf, motorcycle and everyday use. Amber lenses, also referred to as copper, brown or "HD", block blue light which helps to add depth perception. They are good for low-light conditions and block less sunlight than the smoke lens. 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.
