Dynamic Visual Function Trainer and Its Application

Abstract

The invention belongs to the field of optical instruments for visual function training, and in particular relates to a dynamic visual function training instrument and application thereof, comprising a bracket (1), a test disc (2), a guide post for the test disc (3), and an optotype display part (4). ) and the control part (5); the test disc (2) is fixed on the transverse link (7); the test disc guide column (3) is vertically connected to the horizontal working surface of the bracket (1); the transverse link (7) ) is sleeved with the test disc guide post (3); the visual mark display part (4) is slidably connected to the horizontal slide rail (6) on the bracket (1) through the support (8); the bracket (1) is provided with The input part (9) is manually controlled; the control part (5) includes a signal processing part, a CPU and a data storage part; the present invention has simple structure, convenient operation, safety and reliability, no side effects, and changes from passive treatment to active participation, thereby improving the training effect .

Description

technical field [0001] The invention belongs to the field of optical instruments for visual function training, and in particular relates to a dynamic visual function training instrument and its application. Background technique [0002] For myopic teenagers in the growth and development period, with the growth and development and incorrect eye habits, the degree of myopia will continue to increase, the eye axis will continue to elongate, and the intraocular pressure will also increase. [0003] The existing visual function training instrument generally includes a support, a special inspection disc, an optotype, an optotype guide rail, an optotype controller and an inspection disc guide post. Although the operation is convenient, the structure is complicated. In addition, because the visual marks used are E mark, English letters, cross lines and cartoon line drawings, and fixed figures such as C mark, cross lines and concentric circles, the training process is relatively bori...

AI Technical Summary

Problems solved by technology

Although the operation is convenient, the structure is complicated. In addition, because the visual marks used are E mark, English letters, cross lines and cartoon line drawings, and fixed figures such as C mark, cross lines and concentric circles, the training process is relatively boring and difficult. It is boring and cannot attract the user's attention well; due to young people's activeness, poor concentration ability for a long time and forced participation, it affects the enthusiasm of treatment, it is difficult to persist in long-term visual function training, and the desired effect cannot be achieved; Ordinary labels are fixed in a limited order, and it is easy to memorize the direction after using it for a period of time, which affects the training effect
