Arrangement for projecting a two-dimensional image onto an eye to be examined for use with a device that performs a subjective determination of refraction and/or a device that performs other vision functions

An arrangement for projecting a two-dimensional image onto an eve to be examined for use with a device that determines subjective refraction and/or performs other visual functions, comprising:

• at least one light source providing source light;
• at least one light modulator for modulating the source light to produce modulated light;
• a driving unit for controlling said modulator to modulate the source light in accordance with video information corresponding to a video image;
• two-dimensional deflecting means for deflecting the modulated light to produce a two-dimensional image;
• optical transmission means for optically transmitting the light of the light source, said optical transmission means being a light guide;
• optical projection means for optically projecting the two-dimensional image onto a retina of an eye to be examined, the optical projection means projecting light to the two-dimensional deflecting means;
• and
• spectacles with partially or fully reflecting glasses,
• said optical transmission means being comprised of a flexible optical transmitter fastened on both sides to said spectacles, said optical projection means being said glasses, and said glasses reflecting the two-dimensional image onto the retina.
