Abstract
A contact lens () includes an optic zone () that is centred on an optical axis (), and a peripheral zone () surrounds the optic zone (). A cross-sectional slice through the optic zone () along a meridian comprises a series of successive arcs (-) having a radial curvature power profile. The radial curvature power profile increases monotonically with radial distance from the optical axis (). Light rays from a distant point source passing through the midpoint of each arc converge toward a point () on the first optical axis (-). For each arc (-), light rays from a distant point source pass through that arc (-) and converge towards a point () that is spaced away from the optical axis by a first distance. Methods of designing and manufacturing such contact lenses () are also described.
