11. optic nerve note that the retina is disrupted here thus creating a blind spot

12. Find your blind spot: With this diagram about 3 feet away from your face, look at the upper cross with your LEFT eye, then cover your RIGHT eye. The filled circle should disappear –if not, move forward or backward until it does. Then, look at the lower cross and note that the line appears continuous.
