May 27, 2021 · Every human eye has something called a blind spot. This natural blind spot is the place in the retina — the light-sensitive inner lining at the back of your eye — that doesn’t have any cells that respond to light. The blind spot sits in the part of your retina where the optic nerve exits the eye.

Everyone has a spot in their retina where the optic nerve connects. In this area there are no light-sensitive cells so this part of your retina can’t see. We call this the blind spot.
Feb 5, 2024 · Each of your eyes has a small functional blind spot where the optic nerve moves through the retina. This spot is called the optic disc, and it’s 1.5 millimeters in diameter. No cells respond to light (photoreceptors) in this tiny area. The lack of light-sensitive cells causes a blind spot.

Blind spot, small portion of the visual field of each eye that corresponds to the position of the optic disk (also known as the optic nerve head) within the retina. There are no photoreceptors (i.e., rods and cones) in the optic disk, and, therefore, there is no image detection in this area.
