ABSTRACT:
An arrangement for use with a device that determines subjective refraction and/or performs other visual functions, comprises at least one light source, at least one light modulator for modulating the light source to produce modulated light, a driving unit for controlling said modulator to modulate the light source in accordance with video information corresponding to a video image, a two-dimensional deflector for deflecting the modulated light to produce a two-dimensional image, an optical transmitter for optically transmitting the light of the light source, and an optical projector for optically projecting the two-dimensional image onto a retina of an eye to be examined.
