ABSTRACT
School myopia is a most common health problem in schoolchildren, in adolescents in particular. School myopia resulted from connective tissue failure of the whole organism. Some data, such as the association of school myopia with the HLA system confirm this idea. New investigations in this direction will assist in concretizing the real cause of this type of myopia. The interaction between the lighting conditions and the development of refraction is also of interest.

A total of 10 examinees with shortsight at 1.0-3.5 diopters were subjected to study of visual performance similar to work at microscope with regular and chromatic (590 nm) light to tested objects. Chromatic light appeared to result in reliably higher visual performance, especially by the end ot 40-minute experiment. The study used an original method modelling visual work and a formula to calculate performance of work at microscope.

Stability of achromatic vision in regular and chromatic (590 nm) light was examined in 10 myopic (1.0-4.0 diopters) patients. The parameters for chromatic light were better than for the regular one, especially after the visual load of correction by means of Landolt rings for half an hour.
