Solution

Blind spot
The area of the eye when no photoreceptor cells are present is known as a blind spot.
It is the location where the optic nerve exits the eye and the retinal blood vessels enter.
The section of the retina where these photoreceptor cells are missing produces the optic disc, which has a blind spot and no vision in the blind spot area.
