We use many of the same advanced optical techniques you'll find in lenses from these high-end manufacturers. Our lenses are designed and manufactured by Revant Optics to fit into the frames they were meant to replace but keep in mind that none of the original logos or branding will be present on the lenses. Additionally, different companies all have their own proprietary techniques for developing lenses (e.g. Prizm, Chromance, Spy Optics’ Happy lenses). Our lenses are not exactly the same as the originals, but we use similar techniques that are our own. For a bit more detailed information of a full comparison, I've added a few blog posts that might be helpful: Revant vs. Oakley Lenses: An Honest Side-by-Side ComparisonPolycarbonate vs. Glass Lenses We offer lenses that are optically crisp and durable. Not to mention, we've got you covered with our 1-year manufacturer's warranty and 60-day no-hassle return policy.
