Abstract
A shortsightedness monitoring instrument for students is mainly composed of various boxes, various rotary hard planar and light-transmitting sighting mark plates, a midget motor, a central shaft, a handle, a lamp tube, a power switch, a power wire, a rear cover plate and various support assemblies. The shortsightedness monitoring instrument is characterized in that various sighting marks of different specifications are printed on the various rotary hard planar and light-transmitting sighting mark plates. The various rotary hard planar and light-transmitting sighting mark plates are arranged in the various boxes or the support assemblies in a matched mode. Or the various rotary hard planar and light-transmitting sighting mark plates are directly nailed on walls or any other objects in a matched mode through nails or screws. The various rotary hard planar and light-transmitting sighting mark plates are rotated until notches of all upper sighting marks of any one specification face upwards, downwards, leftwards and rightwards respectively. Accordingly, a user who is subjected to a sight test can not recite the sight marks from memory. The shortsightedness monitoring instrument is particularly suitable for accurately learning the state of development of shortsightedness of children in time by parents.
Description
Technical field
This utility model relates to a kind of visual acuity chart giving a test of one's eyesight, and relates in particular to the domestic myopia of student monitor in a kind of rotatable sighting target orientation.
Background technology
For a long time, most of medical institutions or family in society, giving a test of one's eyesight is all to use traditional visual acuity chart.Because the E font sighting target on traditional visual acuity chart is fixed; this fixing sighting target for disposable give a test of one's eyesight more applicable; if just improper to the long-term repeated detection vision of same person; for example: some head of a family stipulates that child's vision is lower than 1.0 or at 0.8 o'clock; require child to see less TV; play less computer, vision protection.Some child for fun, can easy to doly weave into pithy formula by fixing sighting target breach, for example: on 12 times, 3 left 4 right sides etc. recite, and hoodwink the head of a family.Therefore, the head of a family cannot accurately grasp child's visual deterioration degree, cannot persuade child to see less TV, plays less computer, vision protection.In the time that child becomes medium myopia, the head of a family is also kept in the dark and does not know.In addition, this traditional visual acuity chart also has weak point for serve in the army personnel's vision of inspection, and some people has defective vision, and can advance to inspection unit sighting target breach is recited.Comprehensively above-mentioned, traditional visual acuity chart has weak point.
Current myopia of student eye is very many, and myopia number is in continuous increase, and myopia degree is also in continuous rising.Therefore, some heads of a family needs in time, accurately, grasp child's near-sighted situation, be badly in need of a kind of simple and practically, cannot remember again the Novel visual acuity chart of reciting sighting target breach direction.
Simple and practical, cannot remember again the Novel visual acuity chart of reciting sighting target breach direction, also do not have on the market.
Summary of the invention
For the problems referred to above, this utility model object be to provide a kind of parents of student of allowing in time, accurately, grasp child's myopia situation, cannot remember and recite sighting target breach direction, myopia of student monitor.
In order to achieve the above object, the technical scheme of this utility model myopia of student monitor is as follows: myopia of student monitor mainly comprises: the formations such as various casings, various rotatable sighting target dish, central shaft, handle, fluorescent tube, on and off switch, power line, back shroud, various bracket assemblys.Various rotatable sighting target dishes are circular flat structure, coordinate and be arranged in various casings, or moving cooperation is arranged on various bracket assemblys take central point or central shaft as benchmark is moving.On various rotatable sighting target dishes, be printed with the various sighting targets of all size specification.Rotate various rotatable sighting target dishes, turn to the sighting target breach of any same specification on top respectively towards different up and down directions, therefore, detected vision person cannot remember and recites.If need to increase detection difficulty, also can require detected vision person point out on 45 degree oblique angles sighting target breach oblique towards.This utility model is particularly suitable for parents of student and promptly and accurately grasps child's myopia state of development, persuades child to see less TV, plays less computer, vision protection.
