Size Guide: Medium size fit Make a statement with Horizon where style meets technology. The refreshed vintage navigator frame front is “punched out” from a single titanium sheet with a sleek look that's as light as can be. The technology also allows for no soldering on the frame front. Horizon also features handmade acetate temples and groundbreaking polarized photochromic lens options with our signature Blue Water and Evergreen mirror coatings. Lightweight and impact-resistant, our photochromic lenses automatically lighten and darken in different light conditions to protect your vision and enhance clarity. Horizon is also available with non-photochromic Graphite lens.
