Problems solved by technology

As a result, there have been two pairs of isotropic spectacle lenses with opposite signs arranged up and down in the market to measure the adjustment sensitivity. However, this method requires the assistance of parents to count the cycles completed by the subjects per minute, which is too time-consuming and troublesome, and does not take into account the lenses. The magnification rate and no uniform implementation standards make it difficult for students and parents to adhere to

Abstract

An adjustment sensitivity test training instrument is composed of a box body and related components in the box body. The upper end of the front of the box body is provided with a lens optical center distance adjusting screw. Rotary knobs are arranged on the two sides of the lens optical center distance adjusting screw. A bottom plate is connected with the lens optical center distance adjusting screw. A lens plate is connected with the bottom plate through a lens plate axle hole. A lens is embedded in the lens plate. The symmetrical parts of the box body and the bottom plate are provided with a front panel observing hole and a bottom plate observing hole respectively, and the holes are consistent with the lens in the front and back direction. According to the adjustment sensitivity test training instrument, the whole running process is controlled through a set chip and a computer, the accuracy and credibility of the test result can be improved through the innovative utilizing of the performance of an MP4 or a computer displayer, and meanwhile enjoyment and practicality are improved.

Description

technical field [0001] The invention relates to articles for the prevention and control of myopia for teenagers, in particular to an adjustment sensitivity testing and training instrument. Background technique [0002] The cause of the occurrence and development of myopia in adolescents has been unknown. After years of experiments and research, relevant experts have reached a consensus in recent years that the main pathogenesis of myopia in adolescents is the lack of adjustment ability and reduced adjustment sensitivity when seeing near. As a result, there have been two pairs of isotropic spectacle lenses with opposite signs arranged up and down in the market to measure the adjustment sensitivity. However, this method requires the assistance of parents to count the cycles completed by the subjects per minute, which is too time-consuming and troublesome, and does not take into account the lenses. The magnification rate and no uniform implementation standards make it difficult...
