These unique multi-purpose sunglasses have the ability to function as a typical pair of sunglasses, a pair of foam riding glasses, or a pair of goggles. The "EPOCH Hybrid" model comes with vented foam padding which when removed leaves the frame open like a typical pair of sunglasses. The interchangeable strap and ear stocks of these glasses are designed to offer the ultimate in versatility. 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.
