Abstract
A variable focus contact lens, has a body with a first half and an opposite second half. The body also has a first peripheral surface, an opposite second peripheral surface and an associated focal length. The lens includes a first material having a resilience so that as compressive force is applied to the first surface and the second surface, the focal length of the lens changes in proportion to the compressive force. A force-distributing structure is disposed within the lens for distributing force within the lens so as to inhibit astigmatism in the lens as compressive force is applied to the first surface and the second surface.
