Short answer .....yes

The vertebrate eye contains about 125 million "rod" cells which distinguish between light and dark and close to 6 million "cone" cells which distinguish colours.
Each cone cell contains a visual pigment which absorbs light of a particular wavelength, generally between 400 and 700 nanometres (nm); the range of visible light. Wavelengths between 300 and 400 nm make ultraviolet (UV) light.
