sight1/siet/ noun

the process or, power, or function of seeing; specif the one of the five basic physical senses by which light received by the eye is interpreted by the brain as a representation of the forms, brightness, and colour of the objects of the real world

Sight – one of the five senses – is the process by which light received by the eye is interpreted by the brain as a representation of the forms, brightness and colour of the objects of the real world. Light received by the eye is refracted by the cornea before passing through the lens where the image is focused onto the retina and inverted. A coded form of the image is then transmitted from the retina via the optic nerve to the cerebral cortex of the brain — Dr John Cormack
