What is a blindspot in vision?
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.
What is the blind spot and why is it so called?
Your retina is covered in light-sensitive cells, which send messages to your brain about what you see. 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.
