The patent pended Cornea is based on the POC innovation of attaching the lens on the outside of the frame, to enlarge the field of view. Cornea has extensions bars which gives a much better fit to the face. The lens is a perfectly shaped, injected cylindrical PC screen for superb optical qualities. To avoid steaming the inner lens is made of CP and laminated exactly parallel to the outer lens. POC continues the journey to make the “changing lenses panic” a piece of cake.
