Definitions:

Photoreceptors

Specialized cells found in the retina of the eye that convert light into electrical signals, facilitating vision.

Retina

A layer at the back of the eyeball containing cells that are sensitive to light and that trigger nerve impulses that pass via the optic nerve to the brain, where a visual image is formed.

Optic Nerve

The nerve that transmits visual information from the retina to the brain.

Choroid Layer

A layer of the eye containing blood vessels and pigment cells, located between the retina and the sclera, primarily responsible for providing oxygen and nourishment to the outer layers of the retina.
