उत्तर
The blind spot is known as the area of 'no vision' because it completely lacks photoreceptor cells, containing neither rods nor cones. It is the specific point on the posterior retina where the optic nerve exits the eyeball to transmit impulses to the brain and where the retinal blood vessels enter, rendering it entirely insensitive to light so that no image can be formed on it.
