Desk-type vision function training device

Abstract

The invention relates to visual training equipment, in particular to a desk-type vision function training device. The desk-type vision function training device comprises a training platform, a visiondetection device is arranged at one end of the upper surface of the training platform and comprises two columns which are vertically arranged at the two sides of the training platform, slide grooves are oppositely formed in the two opposite sides of the columns, the two ends of an adjusting plate are in vertical sliding fit with the interiors of the slide grooves, a long-strip-shaped hole horizontally penetrates through the middle of the adjusting plate, the vision detection device comprises two discs, spherical lenses are distributed in the radial direction of the discs, the center of circleof each disc is rotatably installed on the adjusting plate, and the vision detection device further comprises a disc rotating mechanism which is used for driving the discs to rotate around the centerof circle of the discs themselves and a disc moving mechanism which is used for driving the discs to move in the direction close to or away from the long-strip-shaped hole, and also comprises a heightadjusting mechanism which is used for adjusting the height of the adjusting plate.

Description

technical field [0001] The invention relates to a vision training device, in particular to a desktop vision function training device. Background technique [0002] In modern society, people's life pressure is increasing. With the advancement of science and technology, people gradually use computers to work. It is getting higher and higher, but the excessive use of electronic products has caused more and more serious problems to people's health, such as curvature of the spine and decreased vision. When vision drops to a certain level, there will be a risk of inheritance to future generations, so people pay more and more attention to their own vision and use desktop visual function training devices. [0003] The existing visual function training device has a complex structure, including two types: head-mounted and instrument table. The head-mounted type is to wear the visual function training device on the eye, and the target object is reflected to the human eye through the p...

AI Technical Summary

Problems solved by technology

The existing instrument desktop visual function training device cannot adjust the position of the lens according to the demand, resulting in that the lens does not correspond to the pupil of the human eye, so that the target object entering the human eye cannot accurately fall on the retina, which is not conducive to adjusting vision, and the height of the lens is too high If the height of the lens is too high, the target object will not enter the human eye, there will be no adjustment effect, and even damage the vision
