What is the blind spot and why is it so called?
Everyone has a spot in the retina where the optic nerve connects. In this area, there are no light sensitive cells, so this part of your retina cannot see. We call this the blind spot. Your blind spot is not usually noticeable because your two eyes work together to cover up each eye’s blind spot.
