Vision training instrument capable of regulating and controlling stimulating light sources and implementation method of vision training device

Abstract

The invention discloses a vision training instrument capable of regulating and controlling stimulating light sources and an implementation method of the vision training instrument. The vision training instrument comprises a stimulating light source providing device, a display screen moving device and a center control system, wherein the stimulating light source providing device comprises a plurality of independent polygon display screens; the display screen moving device comprises a frame and multiple retractor devices, and the retractor devices are fixed on the frame; each display screen is fixed on the corresponding retractor device; the display screens are mutually embedded to be spliced to form a near hemispherical display structure; the retractor devices are used for controlling the movement of the display screens; the center control system is connected with the stimulating light source providing device and the display screen moving device; the stimulating light source providing device is used for providing the stimulating light sources; and the center control system is used for regulating and controlling the information of the stimulating light sources sent by the display screens. By using the vision training instrument, retinas of human eyes at different regions are pertinently stimulated, thereby achieving the functions of controlling the increment of short sight, controlling axix oxuli to elongate and promoting the transfer of a retina nerve signal.

Description

technical field [0001] The invention relates to a visual training device, in particular to a visual training device and a realization method capable of regulating a stimulating light source. Background technique [0002] The current visual training instruments all concentrate the stimulation signals in the central area of ​​the retina, lacking effective means and methods for targeted regional stimulation. In fact, the visual cells on the human retina are mainly composed of cone cells (within 10 degrees in the central area) in the macular area, and mainly composed of rod cells in the peripheral area. The shape and function of these two different cells are similar. There are significant differences. To improve the visual function of amblyopia patients, different stimulation methods in different regions should be adopted to fully restore visual ability. That is to say, different training methods should be used for cone cells and rod cells, such as The use of 640nm red light in...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a visual training device and its realization method which can control the stimulating light source, aiming to solve the problem that the existing visual training device concentrates the stimulating signal in the central area of ​​the retina, and cannot effectively stimulate different areas, which leads to the treatment of underperforming problems
