The light sensitive cells of the eye are located in which layer?

Explanation:
Light detection happens in the retina, the light-sensitive neural layer lining the back of the eye. Photoreceptors called rods and cones reside there, converting light into electrical signals that the brain can interpret. Light first passes through the cornea and lens to be focused onto this layer. The cornea is the transparent front surface that helps focus light but doesn’t detect it. The sclera is the tough white outer coat that protects the eye. The choroid lies between the retina and sclera, supplying blood and absorbing excess light, but it isn’t light-sensitive.
