Answer:
The region of retina devoid of photoreceptor cells (rod cells and cone cells)
Explanation:
The retina is the layer of the eyeball and is packed with rod cells and cone cells responsible for night and day vision respectively. The blind spot is the region in the retina where no rod cells and cone cells are present.
Absence of these photoreceptor cells ensures that no vision is formed in this part of the retina. However, the blind spot serves as the site from where the optic nerve passes through the retina and serves to transmit the impulse to the brain.
