Blind Spot

The area in the human visual field that lacks light-detecting photoreceptor cells, resulting from the optic nerve head's location on the retina.

Bipolar Cells

Cells found in the retina of the eye that act as intermediaries between photoreceptors (rods and cones) and ganglion cells, transmitting visual information.

Optic Nerve

The optic nerve is a paired cranial nerve that transmits visual information from the retina to the brain.
