Optical Element for Correcting Color Blindness

Abstract

Described herein are devices, compositions, and methods for improving color discernment.

What is claimed is: 
     
         1 . An ocular lens comprising: an optical element comprising a luminescent compound in a substantially transparent matrix; wherein the device is configured so that optical element modifies a color of an object or image viewed through the optical element by a user to thereby allow the user to better distinguish colors. 
     
     
         2 . The ocular lens of  claim 1 , wherein the ocular lens is an intraocular lens. 
     
     
         3 . The ocular lens of  claim 1 , wherein the ocular lens is a hard contact lens. 
     
     
         4 . The ocular lens of  claim 1 , wherein the ocular lens is a soft contact lens. 
     
     
         5 . The ocular lens of  claim 1 , wherein the optical element comprises a hydrogel polymer. 
     
     
         6 . The ocular lens of  claim 5 , wherein the hydrogel polymer incorporates a hydrophilic acrylate monomer. 
     
     
         7 . The ocular lens of  claim 6 , wherein the hydrogel polymer further incorporates an alkyl acrylate monomer or an alkyl methacrylate monomer. 
     
     
         8 . The ocular lens of  claim 1 , wherein the optical element absorbs light in a wavelength range near peak sensitivity for an M human cone photopigment and emits light of a longer wavelength in a wavelength range near peak sensitivity for an L human cone photopigment. 
     
     
         9 . The ocular lens of  claim 8 , wherein the optical element has a peak wavelength of visible absorption of about 510 nm to about 550 nm. 
     
     
         10 . The ocular lens of  claim 9 , wherein the optical element has a peak wavelength of visible emission of about 540 nm to about 580 nm. 
     
     
         11 . The ocular lens of  claim 1 , wherein the optical element is configured to absorb and emit visible light so that when an object or image is viewed through the optical element, a first color having a first set of color coordinates is converted to a second color having a second set of color coordinates to aid in distinguishing colors; and the distance between the first set of color coordinates and the second set of color coordinates in the direction normal to a color confusion line nearest to the first set of color coordinates is at least about 0.02 color coordinate units. 
     
     
         12 . The ocular lens of  claim 11 , wherein the distance between the first set of color coordinates and the second set of color coordinates in the direction normal to a color confusion line nearest to the first set of color coordinates is at least about 0.04 color coordinate units. 
     
     
         13 . The ocular lens of  claim 11 , wherein the color confusion line is a deuteronopia color confusion line. 
     
     
         14 . The ocular lens of  claim 13 , wherein the color confusion line is deuteronopia color confusion line 7. 
     
     
         15 . The ocular lens of  claim 13 , wherein the color confusion line is deuteronopia color confusion line 8. 
     
     
         16 . The ocular lens of  claim 13 , wherein the color confusion line is deuteronopia color confusion line 9. 
     
     
         17 . The ocular lens of  claim 11 , wherein the first set of color coordinates is about (0.375-0.380, 0.485-0.490), about (0.475-0.480, 0.410-0.415), about (0.368-0.373, 0.485-0.490), or about (0.370-0.375, 0.460-0.465) 
     
     
         18 . The ocular lens of  claim 11 , wherein the first set of color coordinates is about (0.330-0.335, 0.340-0.345), 
     
     
         19 . The ocular lens of  claim 11 , wherein the first set of color coordinates is about (0.570-0.575, 0.340-0.345), about (0.475-0.480, 0.468-0.473), or about (0.565-0.570, 0.395-0.400),
