Sensing based on light, including detection, discrimination and spatial processing.
Visual sensitivity to ultraviolet wavelengths. Its relevance to a colour comparison depends on the receiver’s actual receptors and the illumination.
A light-sensitive receptor protein associated with a chromophore. Sequence, expression, chromophore and neural processing all contribute to visual performance.
Dependence of a receptor or sensory response on wavelength. Define whether the measurement concerns a pigment, receptor, circuit or behaviour.

Vision can refer to different concepts depending on the context: 1. **Biological Vision**: In a biological sense, vision refers to the ability of organisms to perceive their environment through light. It involves the process of capturing light through the eyes, which is then processed by the brain to create an image of the surrounding world. This capability allows individuals to navigate their environment, recognize objects, and understand spatial relationships.
