Abstract

It has been found experimentally that exposure to a low-intensity light changes the human blood plasma absorption spectrum in the range 350 - 550 nm. The action of violet light and green light have opposite directions. The times of development of photoinduced effects are in the order of dozens of seconds, the times of spectrum relaxation after the exposure are in the order of dozens of minutes. Dependences have been studied of the effect on the intensity, dose, and wavelength of the acting light. A phenomenological model is developed which describes qualitatively the experimentally observed effects.
