The Epoch Link is an original design from Epoch Eyewear. The frame includes the most overall inlayed rubber of any of our styles to ensure a perfect fit and durability. These features make this one of our favorite styles. 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.
