A remote vision training device

Abstract

The invention relates to a remote distance visual training device, which comprises a case, a training target, a rotating structure, a step motor, a feedback device, a printed circuit board, a power supply and a background lamp, wherein the training target, the rotating structure, the step motor, the feedback device, the printed circuit board, the power supply and the background lamp are arranged inside the case, the training target is used for providing visual training contents, the rotating structure is used for helping the training target to rotate, the step motor is used for controlling the rotating structure to rotate, the feedback device is used for monitoring the rotating position of the training target, the printed circuit board is used for driving the step motor and the feedback device to work, the power supply is used for providing the power supply for the printed circuit board and the step motor, and the background lamp is used for providing the illumination for the training target. The remote distance visual training device has the advantages that through extending the visual target distance, the visual object light rays are optimized, the pupil regulation is realized, and the myopia incidence is reduced.

Description

technical field [0001] The invention relates to the technical field of medical training and rehabilitation equipment, in particular to a long-distance vision training device. Background technique [0002] China is currently one of the countries with the highest incidence of myopia in the world. The age of onset of myopia is decreasing and the incidence of myopia is increasing year by year. Although the problem of myopia has received extensive attention, with the development of science and technology, more and more electronic products have entered our lives, which has increased the possibility of myopia and made it more difficult to reduce the incidence of myopia. [0003] According to research, the main cause of myopia is excessive use of eyes at close range. Long-term short-distance eye use causes changes in the physiology and structure of the eyeball. In the process of myopia caused by excessive short-distance eye use, the reversible eyeball physiological changes come fir...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is that the existing vision training instrument is too close to the patient's eye during the treatment process, so it is impossible to truly strengthen the adjustment of the patient's eye focus, and instead increase the time and visual burden of the patient's near vision The problem
