Patients with autism could neglect peripheral vision and focus on the central vision for a long period of time. People who are over-sensitiveto vision see the world as if through 2 toilet paper rolls. The vision that is framed by the rolls is like a kaleidoscope, only the vision close to the center is clear enough. Therefore, to see the world at a larger picture, they would lean their heads to one side, to move the objects out of their vision.
