Method and apparatus for modulating prism and curvature change of refractive interfaces

An adaptive lens system comprising:

• i) a lens compartment comprising a transparent cover;
• ii) a deformable transparent optical element mounted in said lens compartment, said optical element comprising an upper surface and a lower surface and thereby forming a sealed upper chamber in said lens compartment between said transparent cover and at least a portion of said upper surface, and also defining a lower region external to said lower surface;
• iii) a first transparent fluid medium in said upper chamber and a second transparent fluid medium in said lower region, said first and second fluid media having different refractive indices;
• iv) a structural element located in and movable in said upper chamber relative to said deformable optical element to mechanically engage said deformable optical element to thereby alter the curvature of said deformable optical element, thereby altering the refractive power or the prismatic effect of said an adaptive lens system.
