Optics

Optics is the study of light and how light interacts with matter and itself. It includes interactions with matter and the construction of instruments that use or detect it. Optical science is revelant and can be studied in many related disciplines which include astronomy, various engineering fields, photography, and in medicine ( which is particularly used in opthalmology and optometry). The practical objects that we use in everyday life include mirrors, lenses, telescopes, microscopes, lasers, and fiber optics.

History of Optic
Although optics was developed with lenses by the Egyptians and Mesopotamians around early 700 B.C. that was made out of polished crystals for Assyrian lenses such for Layard/Nimrud lens, it was Isaac Newton who studied the effects and attributed them to inflexion of light rays. Optics was followed by theories on light and vision that was developed by ancient Greek and Indian philosophers and the development of geometrical optics in the Greco-Roman world. In the early days of Alexandria origniating around circa 300 B.C., Euclid, the earliest surviving Greek treatise on perspective on optics, who described the laws of reflextion in Optica.

Optics is part of everyday life and the central role optics plays as the science of the five senses. Just about everyone benefits from wearing eyeglasses or contact lenses or function a well known popular product we all call the camera to capture photographer of everyday life.
