Which structure is the sensory layer of the eye that detects light and initiates neural signals?

Explanation:
The retina is the sensory layer of the eye that detects light and starts neural signals. It contains photoreceptors—rods and cones—that respond to light and convert it into electrical impulses. These impulses are then processed by other retinal neurons and sent to the brain via the retinal ganglion cells, whose axons form the optic nerve. The lens focuses light onto the retina, but does not detect it. The conjunctiva is a protective surface on the eye, while the optic nerve transports the already-formed neural signals to the brain for interpretation.
