Detailed explanation-1: -The retina of the eye acts like a film of a camera. The eye lens forms an inverted real image of the object on the retina. The retina is a delicate membrane with having an enormous number of light-sensitive cells. The light-sensitive cells get activated upon illumination and generate electrical signals.

Detailed explanation-2: -The retina is a light-sensitive layer at the back of the eye that covers about 65 percent of its interior surface. Photosensitive cells called rods and cones in the retina convert incident light energy into signals that are carried to the brain by the optic nerve.

Detailed explanation-3: -Rods and cones are the light-sensitive cells on the retina.

Detailed explanation-4: -Like film in an older camera or sensors in a digital camera, the retina is a light-sensitive surface where light energy from the outside world is displayed and initiates a reaction that leads to the formation of an image.

Detailed explanation-5: -Photoreceptors. Photoreceptor cells are the specific cells within the retina that convert light into signals for the brain to interpret. You have two types of photoreceptor cells: rods and cones. Rods are very sensitive to light, giving you your night vision.
