Light and myopic refraction in children.

Studies over many years, carried out in different climatic zones of the country, were focussed on the investigation of the role of light in the prophylaxis of development of near-sightedness. It has been found that not only the accommodation reflex but also the pupillary reflex play a role in the enhancement of the optic power of the eye. A scheme of interaction of the mentioned reflexes depending on the level of visible radiation was presented. Provision of optimum illumination is one of the basic conditions for the prevention of eye fatigue and development of myopia.
