Definitions:

Retina

The light-sensitive layer of tissue at the back of the inner eye that converts light images to electrical signals sent to the brain.

Fovea

The fovea is a small depression in the retina of the eye where visual acuity is highest due to the concentration of cones, which are responsible for color vision.

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.
