Description

Vision improvement training instrument

Technical Field

The invention relates to the technical field of vision improvement, in particular to a vision improvement training instrument.

Background

Due to the change of the learning and working modes of the modern society, the myopia crowd is increasingly huge, and particularly, the myopia incidence of teenagers is gradually increased year by year and is high. The causes of myopia are diversified, but it is undeniable that long-time short-distance eye use is one of the main factors of myopia continuous generation and development, and the long-time short-distance eye use causes ciliary muscle to be tense and contracted for a long time, and further spasm occurs, so that pseudomyopia occurs, and the stage is gradually evolved into true myopia if no intervention or improvement is performed. At present, the control means of myopia usually comprises a cornea shaping lens, an optical glasses, a massage device and an instrument, but the control effect of the glasses is limited, the key group of myopia, namely teenagers and school students are heavy, and the design principle of the instrument is not strong in pertinence, the training mode is boring or inconvenient to use, and the control effect and the durability are limited because the instrument cannot attract the interest of students. The principle of the vision improvement training instrument is that under the condition that a target object does not move when myopia people read books, use a mobile phone and a computer, watch television or even watch landscapes, a control system controls a stepping motor to drive an animal lens to reciprocate according to a specific rule, so that distance regularity of eyes continuously generates distance change, namely, distance regularity change between a concave lens and a convex lens is controlled through three preset programs to achieve the purpose of zooming, and therefore non-emmetropic eyes can be induced to see the visual target object clearly and convert the visual target object to emmetropic eyes. The external replaceable lens is suitable for different ametropia crowds, and is suitable for preventing, controlling and improving myopia, astigmatism, amblyopia, ametropia and asthenopia.
