Visual training book

Abstract

The invention discloses a visual training book. The visual training book mainly comprises a carrier on which characters or patterns can be printed, and the characters or the patterns or the combination of the characters and the patterns printed on the carrier, and is characterized in that: the character height of the smallest characters is less than 2mm, the character width of the smallest characters is less than 2mm, the line space of the smallest patterns is less than 1mm, and the characters and lines is clearly recognized by people with normal vision. When the visual training book is used, the characters or the patterns are industriously recognized by amblyopic eyes or astigmatic eyes; larger characters or patterns which are easily recognized are firstly recognized; and smaller characters or patterns are gradually recognized; and smaller and smaller characters and patterns can be recognized by training for more than 30 minutes each day. The characters and patterns are fine, so that a large training space and high strength can be achieved; and a user can select favorite characters or patterns for the training, so that the visual training book has high interest and the user is intent during the training. Multiple users use the visual training book to prove that: by the visual training book, the vision of the amblyopic eyes or the astigmatic eyes can be effectively improved.

Description

Technical field [0001] The invention belongs to a device for eye rehabilitation training, in particular to a vision training book. Background technique [0002] At present, the treatment of amblyopia in major hospitals in my country generally adopts the fine vision training method, and there are three important factors that determine the efficacy of this therapy: the equipment used, the patient's concentration and persistence. Among them, needle threading training is a common method for fine vision training, which is to let the amblyopic person thread a thin thread into the needle nostril hundreds of times a day. However, this method has a little effect in the first few days, but after a few days of needle threading proficiency, The amblyopic person can complete this action without eye gaze, and the amblyopic person is also tired of this repetitive monotonous action, so the curative effect is also greatly reduced; More patterns and line training are more interesting than th...

Among them, needle threading training is a common method for fine vision training, which is to let the amblyopic person thread a thin thread into the needle nostril hundreds of times a day. However, this method has a little effect in the first few days, but after a few days of needle threading proficiency, The amblyopic person can complete this action without eye gaze, and the amblyopic person is also tired of this repetitive monotonous action, so the curative effect is also greatly reduced; More patterns and line training are more interesting than threading needles, but it is impossible to design the lines to be extremely thin due to the limitation of the clarity of the computer monitor, and the distance between the minimum lines required to be distinguished is mostly more than 1mm , can not reach the minimum resolution distance that can be achieved by normal vision, so the training effect on amblyopia is not ideal

In addition, astigmatism is arranged to wear glasses in major hospitals in our country, but there is no substantial treatment
