 Abstract: The superposition eyes of many insect species show, when dark adapted, the phenomenon of eye glow (literature in HOEGLUND, 1966). It is changed by light induced pigment migration: initially a bright disc is visible in the eye which gradually becomes darker and contracts concentrically. This process was explained by EXNER (1891) on the basis of the superposition ray path. In the incident light microscope an additional observation can be made: the initially completely illuminated surface of each single facet is gradually reduced by a dark zone progressing from the edge to the centre; simultaneously its brightness decreases. This process was already observed by KIESEL (1894), however, with eyes which were immersed in a highly refracting medium in order to avoid reflexion and refraction by the corneal surface. In the following this observation is made with optically intact eyes. It allows conclusions on the nature of the dioptric apparatus of superposition eye ommatidia, and on the interference of pigment migration with the ray path which it produces.
