Multiple Choice

Which is the light sensitive layer of the eye that contains rods and cones?

Light detection happens in the retina, the light sensitive layer of the eye that houses the photoreceptors called rods and cones. Rods enable vision in dim light and peripheral vision, while cones handle color and fine detail. Light travels through the cornea, pupil, and lens and is focused onto the retina, where these photoreceptors convert light into electrical signals that travel to the brain via the optic nerve. The iris adjusts pupil size, the choroid supplies blood to the eye, and the lens focuses light but does not detect it. So the retina is the layer that contains rods and cones and is responsible for detecting light.
