Abstract
Apparatus, systems and methods for facilitating actuatable contact lenses are provided. In one aspect, the contact lens can include: a substrate comprised of a material that is actuatable to at least one of change a base curvature from a first curvature to a second curvature or change a thickness from a first thickness to a second thickness; and a control component, operably coupled to the material, that outputs actuation information to cause the material to actuate and at least one of change the base curvature of the material or change the thickness of the material. The contact lens can be actuated based on a condition associated with an environment surrounding the contact lens, a sensed prescription for an eye over which the contact lens is placed or based on a focal point of the eye. The material can include piezoelectric film, a shape memory alloy, hydrogel and/or silicone elastomer.
