The extramission or emission theory was forwarded by the mathematicians Euclid  and Ptolemy who asserted that certain forms of radiation are emitted from the eyes onto the object which is being seen. The strongest influence on the Book of Optics was ophics Ptolemy’s Opticswhile the description of the anatomy and physiology of the eye was based on Galen’s account. CNRS7 1: Alhazen continued to live in Cairo, in the neighborhood of the famous University of al-Azharand lived from the proceeds of his literary production  until his death in c.
The Book of Optics Arabic: Subsequently, by the time da Vinci v’ould consider the wotks of these same opticalscientists, he too would be forcedto reconcilefor himselfthe relationship between vision. Opticcs synthesis of light and vision adhered to the Pf scheme, exhaustively describing the process of vision in a logical, complete fashion.
Because visionis a cognitiveprocessinvolvinginner senseand intellect, opticslinks sightwith semantics, semiotics, and theoriesof the soul. Mark Smith has accounted for 18 full or near-complete manuscripts, and five fragments, which are preserved in 14 locations, including one in the Bodleian Library at Oxfordand one in the library of Bruges. 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 perception.

During many years living in Egypt, ten of which were spent underwhat we may now call protective custody house arresthe composed one of his most celebrated works, the Kitab al-Manazir, whose title is commonly translated into English as Book of Optics but more properly has the broader meaning Book of Vision. The suggestion of mechanical models for the Earth centred Ptolemaic model “greatly contributed to the eventual triumph of the Ptolemaic system among the Christians of the West”.
The Book of Optics Ibn Al‐Haytham; Alhazen | Arip Nurahman –
The Kitab al-Manazir Book of Optics describes several experimental observations that Alhazen made and how he used his results to explain certain optical phenomena using mechanical analogies. Quon raken’ro’r a r-an. Essentially Ibn al-Haytham took a new view of light, combined it with Ptolemaic optics, Galenic anatomy and the results of his own extensive experiments and produced a plausible intromission view that lasted until Kepler.
In the Book of Opticsal-Haytham oof the existence of primary and secondary light, with primary light being the stronger or more intense of the two. Zlhazen argued that if the object sends an infinite amount of rays of light to the eye, only one of these lines falls on the eye perpendicularly: Articles containing Arabic-language text. He further states, “If one can believe Rafaello Maffei, the ancient scienceof Alhazen and Vitellio now included artistic applications and was almosr identified with the fine arts” Klein, ,p.
According to this theory, the object being viewed is considered to be a compilation of an infinite amount of points, from which rays of light are projected. It is only in recent years that it has been recognized that there is indeed no perception without eye movements and that eye movements are crucial to building up our consciousness of the visual world . Alhazen’s most original contribution was that after describing how he thought the eye was anatomically constructed, he went on to consider how this anatomy would behave functionally as an optical system.
Given a light source and a spherical ball of certain refractive index, the closest point on the spherical ball where the light is refracted to the eye of the observer can be obtained by solving a tenth degree equation.
Ibn al-Haytham was the first to explain that vision occurs when light bounces on an object and then is directed to one’s eyes. Item Vitellonis Thuringopoloni Libri X.

Ibn Al-Haytham on Eye and Brain, Vision and Perception
Alhazen made significant contributions to optics, number theory, geometry, astronomy and natural philosophy. Thus, its main application in optics is to solve the problem, “Given a light source and a spherical mirror, find the point on the mirror where the light will be reflected to the eye of an observer.
Reprinted in Sabra In al-Haytham’s structure of the eye, the crystalline humor is the part that receives light rays from the object and forms a visual cone, with the object being perceived as the base of the cone and the center of the crystalline humor in the eye as the vertex. In seventeenth century Europe the problems formulated by Ibn al-Haytham — became known as ‘Alhazen’s problem’. Al-Haytham offered many reasons against the extramission theory, pointing to the fact that eyes can be damaged by looking directly at bright lights, such as the sun.
