- Iodopsin is one of three cone pigments responsible for human color vision.
- The iodopsin molecule contains a chromophore that responds to red wavelengths of light.
- Defects in iodopsin production can contribute to certain types of color blindness.
- Scientists study iodopsin to understand how the eye perceives different colors.
- Iodopsin works alongside rhodopsin in the retina to enable vision across different lighting conditions.
