Abstract
A hybrid contact lens has a rigid gas permeable (RGP) central portion and a soft flexible portion that extends outward from the RGP central portion. The soft flexible portion defines the posterior surface and base curve of the hybrid contact lens that contacts a user's cornea, such that the RGP central portion does not contact the user's cornea while wearing the hybrid contact lens. The hybrid contact lens can be a single lens system with one optical power, or a dual lens system with two different optical powers.
