Virtual retinal display
A virtual retinal display (VRD), also known as a retinal scan display (RSD) or retinal projector (RP), is a proposed display technology that draws a raster display (like a television) directly onto the retina of the eye. == History == In the past, similar systems have been made by projecting a defocused image directly in front of the user's eye on a small "screen", normally in the form of large glasses.
