Optical element for correcting color blindness
Described herein are devices, compositions, and methods for improving color discernment.
1. An ocular lens comprising: an optical element comprising a luminescent compound polymerized into a substantially transparent matrix; wherein the lens is configured so that the 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), or about (0.368-0.373, 0.485-0.490).
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).
20. The ocular lens of claim 11 , wherein the first set of color coordinates is about (0.510-0.515, 0.340-0.344), or about (0.480-0.485, 0.388-0.392).
