Describe the reason why humans have a blind spot in their vision.

Our eyes have a blind spot for a very good reason. On the back of our eye, the retina is the stuff that detects the light. All the information that the retina picks up is sent to the brain through the optic nerve. The only problem is that the optic nerve needs a way to get out of the eye. The place where it leaves is where we have our blind spot. Since we have 2 eyes that can move around, we don't notice the blind spot often.
