Artificial Eye

A physical device constructed from optical components to simulate the optical properties of a human eye. Typically consisting of a lens, adjustable aperture (simulating the iris), and an image sensor (simulating the retina), artificial eyes are used in vision research to test and validate optical correction techniques under controlled conditions before applying them to human subjects. In accessibility research, artificial eyes have been used to verify display pre-compensation methods designed to help people with visual aberrations see computer screens more clearly.
