Both ends of Cornea

Solution:
Blindspot
The eye lens focuses light on the back of the eye, on a layer called the retina.
The retina contains several nerve cells.
Sensations felt by the nerve cells are then transmitted to the brain through the optic nerve.
At the junction of the optic nerve and the retina, there are no sensory cells, so no vision is possible at that spot.
This is called the blind spot.
