摘要

As a supplement to Patent Application P 3102381.0, the invention relates to a further development of arrangements for performing vision tests by means of an optotype carrier illuminated from the back. It comprises two possible variants of this arrangement, namely: a) a double arrangement of optotype carrier and flat display serving - by self-illumination or reflection - as illumination source, b) a triple arrangement of optotype carrier and flat display serving transmissively as the light valve plane for a static illumination source connected downstream.
