Born in 965 in Iraq, Ibn al Haytam is known for his work "Kitab Al-Manazir", a hypothesis in the sense of accurate vision. Although inspired by Ptolemy's "Optics" IN THE 2ND CENTURY, IBN AL HAYTAM'S RESEARCH ON THE EYE MODEL COMBINED PRACTICE WITH MATHEMATICAL LOGICAL EXPLANATIONS.

Ibn al Haytam's work also contained a complete formulation of the law of reflection and a detailed investigation of refraction, including experiments involving angles of incidence and deviations. 

in Ḥall shukūk fī Kitāb Uqlīdis ("Solution of Euclid's Elemental Difficulties") Ibn al Haytam solved Euclid's thereoms using direct evidence. He made a lengthy study of parallel lines in Sharḥ muṣādarāt Kitāb Uqlīdis ("Commentary on Euclid's Elemental Premise") and based his treatment of parallels on equidistant lines rather than Euclid's definition of lines never meeting.
