Abstract
A hybrid contact lens comprises a central zone comprising a substantially rigid, gas permeable material having a DK of at least 30, a relatively soft peripheral zone and an intermediate zone comprising a film or coating that is created around the central zone, and then cured. The film facilitates chemical bonding between the central zone and the peripheral zone, and also provides a protective barrier to prevent modification of the physical characteristics of the central zone. The film may be created by soaking the central zone in a chemical solution for a predetermined amount of soaking time.
