- History of optics - Wikipedia
Optics began with the development of lenses by the ancient Egyptians and Mesopotamians, followed by theories on light and vision developed by ancient Greek philosophers, and the development of geometrical optics in the Greco-Roman world

- Optics | History, Applications, Facts | Britannica
There are two major branches of optics, physical and geometrical Physical optics deals primarily with the nature and properties of light itself Geometrical optics has to do with the principles that govern the image-forming properties of lenses, mirrors, and other devices that make use of light
- Optics - Simple English Wikipedia, the free encyclopedia
Optics is the science of light and how it interacts with the world Optics explains how rainbows exist, how light reflects off mirrors, how light refracts through glass or water, and what splits light shining through a prism

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
- Optical telescope - Wikipedia
