What is optical definition?

Optical definition refers to the clarity and sharpness of an image as it is viewed by the human eye. It is determined by various factors such as the quality of lenses, the level of refraction, and the presence of distortions or aberrations. The term "optical" also refers to devices that use light to function, such as optical scanners, fiber optic cables, and telescopes. These devices rely on the manipulation of light in order to transmit or capture information, allowing for various technological applications. Optical definition is an important factor in many areas, including photography, astronomy, and medical imaging.
