The Freebase is a new style of thinking for Optic. We've taken a pure performance interchangeable lens frame and combined it with the advantage of feminine based ergonomics and colors. This smaller sized frame offers all the punch of a standard high performance interchangeable style, in a more compact version that's just right for the petite lady with the heart of a champion. The package comes with a hard shell case and 4 sets of interchangeable lenses in smoke, copper, orange and clear for virtually all conditions.
