The first person to realise that rays of light enters the eye, rather than leaving it, was the 10th century Muslim mathematician, astronomer and physicist Ibn al-Haytham (Alhazen), who is regarded as the "father of optics".He is also credited with being the first man to shift physics from a philosophical activity to an experimental one, with his development of the scientific method.
