[The role of light in pathogenesis of refractive errors].
OBJECTIVE
To present and account the results of newest experimental and clinical investigations on the subject of the light effect on the creation of refractive errors.


METHODS
A review of literature concerning the role of the light in the refractive errors' pathogenesis has been performed.


RESULTS
The influence of continuous light and night adaptation on the eyeball development as well as on the creation of refractive errors in experimental conditions are discussed. The anatomical and biochemical changes taking place in the course of experimental myopia are described. The entities of diseases predisposing to the creation of myopia are characterized. The results of the newest clinical investigations in which was shown that myopia and hyperopia might be associated with sleeping in lighted rooms up to the age of two are presented as well as accounted.


CONCLUSIONS
Light and darkness play an important role in the proper eye development. Disturbance of the diurnal cycle over the time during which refraction forms may create refractive errors.
