"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. The word optics is derived from the Greek term \u03C4\u03B1 \u1F40\u03C0\u03C4\u03B9\u03BA\u03AC which refers to matters of vision."@en . . .
