Abstract

An apparatus and method for forming a contact lens includes submerging a convex optical quality surface of a forming optic in a reservoir containing Lens Reactive Mixture, projecting a first Actinic Radiation with a first wavelength through pre-selected regions of the forming optic that correspond to increased thickness in the lens to be formed for selectively polymerize the Lens Reactive Mixture on a Voxel by Voxel basis; projecting a second Actinic Radiation with a different wavelength through the entire forming optic to selectively polymerize the Lens Reactive Mixture on a Voxel by Voxel basis, removing the forming optic and polymerized Lens Reactive Mixture from the reservoir and applying a Fixing Radiation to form the contact lens.
