Modern white light emitting diodes (LED) have an expressed emission band in a blue and dark-blue interval of 440-460 nm, which completely coincides with the spectrum causing photochemical damage of eye retina and its pigmented epithelium. This radiation represents an increased level of risk danger for the eyes in children and teenagers, because their crystalline lenses are twice as transparent in the blue and dark-blue interval than adult eyes. Photochemical damage of the retina progresses over a long period of time and causes gradual irreversible degradation of sight. The use of luminaires with LEDs in childcare facilities of the Russian Federation can have unpredictable negative and irreversible consequences for children's sight, and demand a serious professional ophthalmology and physiological substantiation.
