What makes the blind spot of the retina blind?
a. It is at a location where the lens cannot focus the light.
b. It is usually damaged during the process of birth. c. The optic nerve and blood vessels occupy this space, leaving no room for receptors.

Bipolar Cells collect signals from Rods and Cones.
B.
