Osmosis video - Photoreception

Photoreception is the process by which photoreceptor cells transduce light energy into electrical energy. Human photoreceptor cells are rods and cones found within the retina. Rods are mainly used for night vision, have a high sensitivity to light, and a low visual acuity, whereas cones are mainly used for color vision, have a low sensitivity to light, and a high visual acuity.
