The Epoch Link is the first of many original designs from Epoch Eyewear. The inlaid rubber makes the arms extremely flexible, forgiving and most of all comfortable. This is our first frame to feature an embossed logo and snap hinges on the arms. These features add to the value, comfort and durability of this year's favorite sunglasses. 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.
