Dynamic visual function training instrument and application thereof

Abstract

The invention belongs to the field of an optical instrument for training of visual functions and especially relates to a dynamic visual function training instrument and application thereof. The dynamic visual function training instrument comprises a bracket (1), an optometry box (2), an optometry box guide column (3), a sighting mark displaying part (4) and a control part (5); the optometry box (2) is fixed on a transverse connecting rod (7); the optometry box guide column (3) is vertically connected with the horizontal working surface of the bracket (1); the transverse connecting rod (7) sleeves the optometry box guide column (3); the sighting mark displaying part (4) is in sliding connection with a horizontal sliding rail (6) on the bracket (1); the bracket (1) is provided with a manual control and input part (9); and the control part (5) comprises a signal processing part, a CPU (Central Processing Unit) and a data storage part. The dynamic visual function training instrument is simple in structure and convenient in operation, is safe and reliable and has no side-effects; the passive treatment is changed into active participation and the training effect is improved.

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 column. 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 bo...

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
