Claim 0:
1. A computer-implemented method of designing a fluid-filled contact lens, wherein the fluid-filled contact lens includes a fluid filled reservoir, the method comprises:
(a) generating a computational model, wherein the computational model comprises a fluid-filled lens and an eye having a cornea, and wherein in the computational model, the fluid-filled lens is modelled on the cornea such that simulated forces of a shape of the cornea act on the fluid-filled lens, which cause deformation to a fluid filled reservoir provided between a first lens member and a second lens member of the fluid-filled lens, and hence alters the optical properties of the fluid-filled lens, thereby generating a deformed, fluid-filled lens;
(b) modelling the optical properties of the deformed, fluid-filled lens;
(c) within the computational model, removing the fluid-filled lens from the cornea and adjusting the shape of the fluid-filled lens off-eye to reduce the effects of the deformation on the optical properties, thereby providing an adjusted fluid-filled lens; and
(d) generating a corresponding off-eye lens design based on the adjusted fluid-filled lens;
(e) manufacturing a fluid-filled lens based on the off-eye lens design.
