The ancient Greeks thought light discharged from the eye making us see, yet it was Ibn Al-Haitham who demonstrated that people see objects by light reflecting off of them and entering the eye, excusing Euclid and Ptolemy's hypotheses that light was produced from the actual eye.
He developed the primary pin-hole camera in the wake of noticing light entering a hole in the screens, which makes sense of how the eye sees pictures upstanding due for the association between the optic nerve and the brain.
