FIELD: medicine.
SUBSTANCE: presented device for optical correction and training of vision contains optical elements made in the form of lenses with variable focus on liquid crystals, an adjustable constant voltage source connected to the control unit and lenses. The control unit includes an amplitude modulation unit that changes the focus of optical elements in the adjustable range of the maximum values of the focal length value and a frequency block specifying the indicated frequency of changes in the focal length. At the same time, the amplitude modulation unit is connected to the sensory adjusters of vision correction and the amplitude of the focal distance fluctuation, and the frequency unit is connected to the sensor frequency controller. The sensor regulators are configured to transmit information to the said blocks.
EFFECT: extended range of technical means.
