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 in a substantially transparent matrix; wherein the device 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;
wherein the luminescent compound absorbs light at an absorption wavelength and emits light at an emission wavelength, wherein a human cone photopigment is substantially more sensitive to the emission wavelength than to the absorption wavelength;
wherein the luminescent compound has an average wavelength of visible absorption of about 380 nm to about 450 nm.
2. An ocular lens comprising: an optical element comprising a luminescent compound in a substantially transparent matrix; wherein the device 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;
wherein the luminescent compound absorbs light at an absorption wavelength and emits light at an emission wavelength, wherein a human cone photopigment is substantially more sensitive to the emission wavelength than to the absorption wavelength;
wherein the luminescent compound has an average wavelength of visible absorption of about 420 nm to about 480 nm.
3. An ocular lens comprising: an optical element comprising a luminescent compound in a substantially transparent matrix; wherein the device 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;
wherein the luminescent compound absorbs light at an absorption wavelength and emits light at an emission wavelength, wherein a human cone photopigment is substantially more sensitive to the emission wavelength than to the absorption wavelength;
wherein the luminescent compound has an average wavelength of visible emission of about 500 nm to about 600 nm.
