Ibn al-Haytham was the major figure in the study of optics and vision in the Middle Ages and his influence was pervasive for over years.

Thus, a topographically ordered point-to-point representation of the visual world entered the crystalline humor. We must wait until Kepler and Newton in the 17th and 18th centuries for further fundamental understanding of the nature of light and until at least Helmholtz in the 19th century for further advances in understanding visual optids.

Ibn Al-Haytham and the Legacy of Arabic Optics

However, Ibn al-Haytham was forced to concede the impracticability of his project. The importance of Ibn al-Haytham’s idea of a point-to-point projection of the visual world into the brain cannot be over-emphasized.


The book describes how the essential form of light comes from self-luminous bodies and that accidental light comes from objects that obtain and emit light from those self-luminous bodies.

Alhazen’s intromission theory followed al-Kindi and broke with Aristotle in asserting that “from each point of every colored body, illuminated by any light, issue light and color along every straight line that can be drawn from that point”. For example, despite documentary evidence showing that concavelensesand mirrors of high enough quality were availablein the first quarter of the 15thcentury Ilardi,such evidencehas done little to achievewide acceptanceby historians that a con- cave mirror can, in fact, project useful imagesfor artists Campbell, Syson,Falo- mir.

Light can be refracted by going through partially transparent objects and can also be reflected by striking smooth objects such as mirrors, traveling in straight lines in both cases.


During the Middle Ages his books on cosmology were translated into Latin, Hebrew and other languages. Therefore, the Moon appears closer and smaller high in the sky, and further and larger on the horizon. Professor Gross concludes that, although Ibn al-Haytham’s unique synthesis of physics, mathematics and physiology into a new theory of vision and its historical importance have been recognized, his insights into the psychology of perception and their influence remains an important and potentially fertile area of research.

In mathematicsAlhazen built on the mathematical works of Euclid and Thabit ibn Qurra and worked on “the beginnings of the link between algebra and geometry.
