Abstract
A method of designing a fluid-filled contact lens (103) is described. The method involves generating a computational model that includes a fluid-filled lens (103) and the shape of a cornea causes deformation of an internal structure of the fluid-filled lens (103) to generate a deformed, fluid-filled lens (103) with altered optical properties. The method also includes modelling (5) the optical properties of the deformed, fluid-filled lens (103). The shape of the fluid-filled lens (103) is then adjusted (7) to reduce the effects of the deformation on the optical properties. This is referred to as an adjusted fluid-filled lens (103). A corresponding off-eye lens design is generated (110 based on the adjusted fluid-filled lens design.
