  2. Euclid's Optics - Wikipedia

    en.wikipedia.org/wiki/Euclid's_Optics

    Because Optics contributed a new dimension to the study of vision, it influenced later scientists. In particular, Ptolemy used Euclid's mathematical treatment of vision and his idea of a visual cone in combination with physical theories in Ptolemy's Optics, which has been called "one of the most important works on optics written before Newton".

    Alternatively, Euclid's can be interpreted as a mathematical model whose only constraint was to save the phenomena, without the need of a strict correspondence between each theoretical entity and a physical counterpart. Measuring the speed of light was one line of evidence that spelled the end of emission theory as anything other than a metaphor.

    Catoptrics is the title of two texts from ancient Greece: . The Pseudo-Euclidean Catoptrics.This book is attributed to Euclid, [3] although the contents are a mixture of work dating from Euclid's time together with work which dates to the Roman period. [4]

  5. History of optics - Wikipedia

    en.wikipedia.org/wiki/History_of_optics

    The early writers discussed here treated vision more as a geometrical than as a physical, physiological, or psychological problem. The first known author of a treatise on geometrical optics was the geometer Euclid (c. 325 BC–265 BC). Euclid began his study of optics as he began his study of geometry, with a set of self-evident axioms.

  8. Optics and vision - Wikipedia

    en.wikipedia.org/wiki/Optics_and_vision

    Vision of humans and other organisms depends on several organs such as the lens of the eye, and any vision correcting devices, which use optics to focus the image. The eyes of many animals contains a lens that focuses the light of its surroundings onto the retina of the eye. This lens is essential to producing clear images within the eye.
