A blind spot monitor is a vehicle-based sensor device that detects other vehicles located to the driver’s side and rear. Warnings can be visual or audible. Increased warnings indicate potentially hazardous lane changes.

Volvo was the first to introduce blind spot monitors to production automobiles, their Blind Spot Information System (BLIS) used a camera to visually detect vehicles. Some newer and more costly systems use side radar offering better performance and also warn of fast approaching vehicles entering the blind spot.

A blind spot, scotoma, is an obscuration of the visual field. A particular blind spot known as the physiological blind spot, “blind point”, or punctum caecum in medical literature, is the place in the visual field that corresponds to the lack of light-detecting photoreceptor cells on the optic disc of the retina where the optic nerve passes through the optic disc. Since there are no cells to detect light on the optic disc, a part of the field of vision is not perceived. The brain interpolates the blind spot based on surrounding detail and information from the other eye, so the blind spot is not normally perceived.

Although all vertebrates have this blind spot, cephalopod eyes, which are only superficially similar, do not. In them, the optic nerve approaches the receptors from behind, so it does not create a break in the retina. The first documented observation of the phenomenon was in the 1660s by Edme Mariotte in France. At the time it was generally thought that the point at which the optic nerve entered the eye should actually be the most sensitive portion of the retina; however, Mariotte’s discovery disproved this theory.
