optical

Pertaining to vision

Optical relates to light, vision, or the science of optics.

An optical illusion tricks the eye.

Optical fibers transmit data as pulses of light.

Optical instruments like microscopes and telescopes use lenses to manipulate light.

The word often distinguishes light-based technology from alternatives: an optical mouse uses a light sensor rather than a rolling ball.
