Definition of retina in English:
noun (plural retinas or retinaeˈretnˌēˈretnˌī)
A layer at the back of the eyeball containing cells that are sensitive to light and that trigger nerve impulses that pass via the optic nerve to the brain, where a visual image is formed.
- And for vision it is also necessary that there should be visual purple behind the retina and an opaque cornea and iris.
- As with similar work in the United States, the prosthetic retina works by passing artificially stimulating the optic nerve, in line with signals from a tiny digital camera mounted on a pair of glasses.
- The chip captures light that enters the eye, and generates an electrical signal that is transmitted to the overlaying neural cells of the retina.
