/ˈɒptɪkl//ˈɑːptɪkl/

The word "optical" has its roots in the Greek word "ophthals", meaning "eye". The term "optical" came into being in the 16th century, derived from the Greek word "optikos", meaning "of or relating to the eye". This refers to the ability to perceive or manipulate light, which is essential for vision. The term was initially used in the context of the study of light and its behavior, which was pioneered by the ancient Greeks, particularly Euclid and Ptolemy. Over time, the term "optical" expanded to encompass the study of all forms of electromagnetic radiation, including visible light, infrared, and ultraviolet rays. Today, "optical" is used in a wide range of contexts, from physics and engineering to photography and vision science.
