Method and apparatus for constructing a contact lens with optics

Abstract

Various embodiments of the present invention provide systems, methods, and processes for constructing a contact lens. In one embodiment, a contact lens assembly is provided, comprising: a curved polymer polarizer with an aperture; a lenslet disposed inside the aperture, wherein the lenslet enables imaging near objects; and a filter attached to the lenslet. In further embodiments, a method for fabricating a flexible contact lens is provided, comprising: fabricating an element having an extrusion; providing a front concave mold, wherein the front mold has an intrusion to accommodate the extrusion of the optical element; affixing the extrusion of the optical element to the intrusion of the front mold; attaching a back convex mold to the front concave mold, thereby forming a mold cavity; and filling the mold cavity with a pre-polymerized liquid, whereby upon polymerization, the pre-polymerized liquid forms the flexible contact lens and the optical element is partially encapsulated within the lens.

What is claimed is: 
     
         1 . A contact lens assembly, comprising:
 a curved polymer polarizer having an aperture and a first polarization;   a second polymer polarizer having a second polarization; and   a lenslet disposed inside the aperture;   wherein the lenslet enables imaging near objects.   
     
     
         2 . The contact lens assembly of  claim 1 , wherein the lenslet is a refractive lens or a diffractive lens. 
     
     
         3 . The contact lens assembly of  claim 2 , wherein the lenslet has a power that is 40 or more diopters greater than a surrounding power in a surrounding region 
     
     
         4 . The contact lens assembly of  claim 1 , wherein the lenslet is substantially wider in a horizontal direction than in a vertical direction, thereby enabling wider viewing angles in the horizontal direction. 
     
     
         5 . The contact lens assembly of  claim 4  wherein the lenslet has a power that is at least 25 diopters greater than a surrounding power in a surrounding region in the contact lens assembly. 
     
     
         6 . The contact lens assembly of  claim 1 , wherein the lenslet is formed from a pre-polymerized liquid. 
     
     
         7 . The contact lens assembly of  claim 1 , wherein the lenslet is partially encapsulated by the contact lens assembly. 
     
     
         8 . The contact lens assembly of  claim 1 , wherein the lenslet has an optical power sufficient to provide a multifocal capability that corrects presbyopia. 
     
     
         9 . The contact lens assembly of  claim 1 , wherein the lenslet has an optical power sufficient to allow a retina to focus on an object in a spectacle plane. 
     
     
         10 . The contact lens assembly of  claim 1 , wherein the first polarization is circular polarization. 
     
     
         11 . The contact lens assembly of  claim 10 , wherein the circular polarization is right-handed circular polarization.
