- eyeless vision
- Also known as eyeless sight, skin vision, skin reading, finger vision, dermal vision, dermo-optics, dermo-optical perception, paroptic vision, para-optic perception, cutaneous perception, digital sight, and bio-introscopy. All the above terms are used in the parapsychological literature to denote the alleged capability to perceive colours, differences in brightness, and/or formed images through the skin, especially upon touching with the fingertips. The notion of eyeless vision was developed during the era of mesmerism. In 1920, the French author Louis Farigoule (1885-1972), better known as Jules Romains, published an influential account of what he called para-optic perception. During the 1960s the phenomenon became an object ofstudy in the Soviet Union, and, subsequently, in various other countries. In biomedicine eyeless vision is either associated with hysteria, or identified as a type of " synaesthesia (i.e. a member of the group of perceptual phenomena exemplified by "colour hearing). In either case the optical phenomena at hand are interpreted as " visual hallucinations that arise simultaneously with - or subsequently to -a tactile stimulus.ReferencesFarigoule, L. (1920).
