Light-sensitive layer at the back of the eye is the

• A. Retina
• B. Cornea
• C. Iris
• D. Lens

Answer: (A)

Light-sensitive layer at the back of the eye is the retina. It lines the inner surface at the back of the eyeball and contains photoreceptors—rods for dim light and cones for color and detail. When light reaches these cells, they convert it into electrical signals that travel through retinal neurons to the optic nerve and onward to the brain for processing. This region sits at the back, while the cornea is the clear front surface that helps bend light, the iris controls pupil size, and the lens focuses light onto the retina.
