FIELD: medicine.
SUBSTANCE: device for reducing visual strain, comprising at least one semiconductor radiation source in the wavelength range from 360 to 420 nm, which creates in the area of the user's eyes an energy illumination of 2 to 20% of the energy illumination of the user's eyes from the screen and at least one semiconductor radiation source in the wavelength range from 720 to 1700 nm, which creates in the area of the user's eyes an energy illumination of 2 to 80% of the energy illumination of the eyes of the user from the screen, wherein said semiconductor radiation sources are connected to an electronic control unit and are placed in one housing, which is configured to direct radiation of the semiconductor sources into the eyes of the user.
EFFECT: reduced visual strain, visual increase in perceived contrast and colour saturation.
