When our Knock Out frames debuted several years ago, they quickly became a home run. So we thought, what the heck, why not swing for the fences a second time by bringing back this fan-favorite prescription pair? With its bold octagonal silhouette, gorgeous fusion of acetate layers, and unique saddle bridge, Knock Out does more than make you look like, well, a knockout. Add your prescription to our premium shatter-resistant lenses, and you've got a pair that refuses to pull punches."
