Detailed explanation-1: -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. Most of the time you don’t notice your blind spot because the spot in one eye doesn’t match the spot in the other eye.
Detailed explanation-2: -This blind spot is there because the optic nerve fibers pass through the back of your retina inside your eye. Where the nerve passes through there are no cells receiving light. At this tiny spot, which is approximately the size of a pinhead, you are technically blind.
Detailed explanation-3: -The spot where your optic nerve connects to your retina has no light-sensitive cells, so you can’t see anything there. That’s your blind spot.
Detailed explanation-4: -A scotoma is a blind spot or partial loss of vision in what is otherwise a perfectly normal visual field. It might look like a dark, fuzzy, or blurry spot, or it might look like a single spot of flickering light or arcs of light.
