Which sense relies on photoreceptors?

Explanation:
Photoreceptors detect light and form the basis of sight. In the retina, rods and cones respond to light and convert it into electrical signals through phototransduction. These signals travel to the brain via the optic nerve, letting us perceive images, brightness, and color. By contrast, hearing uses hair cells in the inner ear that respond to sound waves, taste uses taste receptor cells that detect chemicals in food, and smell uses olfactory receptors that sense airborne odor molecules. Since photoreceptors are specialized for detecting light, the sense they support is sight.
