The explanation for our "blind spot" in our visual field is that
A) the lens cannot focus all of the visual field onto the retina.
B) blood vessels collect together and enter the eye at the blind spot.
C) rods are less sensitive to light than are cones.
D) retinal cells die with age and overuse, resulting in blind spots.
E) there are no photoreceptors in the retina where the axons exit the eye.

Question

Quizplus · Accepted Answer

The blind spot is caused by the absence of photoreceptors (specifically, rods and cones) in the area where axons from the retina exit the eye to form the optic nerve. This results in a small area in the visual field that is not processed by the brain, leading to a blind spot.
