We just learned about the Opthalmic Artery.
Another part of the eye is the Optic Disc.
At the back of the eye there is a place where all the nerves come together and go out to the brain.
Because this spot has nerves, there are no rods or cones there, so it is like a blind spot in your sight.
There are some fun eye tests that you can do to actually show that you have a blind spot where things disappear from your sight!
