Optical element for correcting color blindness

An electronic device comprising:

• an electronic display comprising a light source;
• and
• an optical element for enhancing color discrimination for a user that has an impaired ability to distinguish colors, the optical element being separate from the light source and completely covering the electronic display, the optical element comprising a photoluminescent compound in a substantially transparent matrix;
• wherein the device is configured so that at least a portion of the light emitted from the display passes through the optical element, and the optical element shifts from a first wavelength to a second wavelength at least some of the light emitted from the display that passes through the optical element;
• and
• wherein the photoluminescent compound comprises at least one of an optionally substituted BODIPY, an optionally substituted BODIPY derivative, an optionally substituted rhodamine, an optionally substituted rhodamine derivative, an optionally substituted Nile red, an optionally substituted fluorescein, an optionally substituted 6-FAM phosphoramidite, an optionally substituted coumarin, an optionally substituted pyrromethene 605, and an optionally substituted perylene derivative dye.
