The correct answer is: All of the above
- Our retina, a thin layer of nerve tissue at the back of our eyes, is made up of tiny light-sensitive cells called photoreceptors.
- When light hits the retina, it sends a burst of electricity to the brain via the optic nerve. Your brain converts signals into images.
- Where the optic nerve connects to the retina, there are no light-sensitive cells, so you can't see anything there. This is your blind spot.
