The Epoch 12 was introduced to offer a fashion full frame that also meets ANSI Z87.1 standards for safety eyewear. The inlaid rubber in the arms is a great accent and ensures a comfortable non-slip fit. Smoke lenses are best for maintaining the true colors of what you're looking at. They block the most amount of light, which will help to reduce eyestrain if you'll be outside for an extended period of time. 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.
