Where are the photoreceptors of the eye located?

Photoreceptors are located on the retina of the eye. These receptors are cones and rods. When we sleep, because of the darkness, our eyes rest and the photoreceptors work normally. You also need to understand about the need for other elements of the eye. For example: the lens is a natural lens that is needed for clear image perception and focusing. The pupil can narrow and dilate to adjust the intensity of the light delivered to the retina. The retina has a “blind spot” at the junction of the optic nerve. There are no photoreceptors in that place.
