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.

Abstract: The present disclosure concerns a tuneable ophthalmic lens 200. The tuneable ophthalmic lens comprises an activated state and a deactivated state. The ophthalmic lens further comprises a central chamber 206b. The ophthalmic lens also comprises a fluid reservoir, the fluid reservoir being in fluid communication with the central chamber. The fluid reservoir comprises a pump for pumping fluid between the fluid reservoir and the central chamber. In the deactivated state the central chamber is substantially empty of fluid 208a. In the activated state the central chamber is not substantially empty of fluid.
