Blind spot , don't believe your eye

4. All humans have blind spots, which are spots where the eye cannot see. The blind spot in an eye corresponds to the spot on the retina where the optical nerve connects the retina to the brain. At this spot there are no light detecting cells and, thus, this spot cannot detect light. A small object can disappear from view at the spot. In everyday life the blind spot goes unnoticed. This is in part as the eye is constantly looking around, getting a wide and varied range of views. It is also in part as the brain uses the information from both eyes to create the single mental vision. What one eye misses, the other often picks up.
