距离传感式防近视眼镜

一.据中国卫生部调查报告,中国青少年近视眼发病率高达60%~70%,远远超过其他国家,排在世界第二位。调查结果显示,大部分青少年近视的原因是握笔、看书的姿势不正确及过度上网、看电视。基于这种现状,我们研制了一种可以预防近视的眼镜,它解决了眼镜不能感应距离预防近视的技术问题同时解决了传统防近视产品设计复杂、成本昂贵和体积大不便于携带的问题。

二.本产品具备以下优点:(1)佩戴者可达到保持与书本距离,纠正坐姿,保护视力的效果,预防兼治疗。(2)整套装置小巧轻便,方便随身携带。(3)可重复充电,循环使用,同时解决了废旧电池的环境污染问题,达到保护环境的效果。(4)成本低廉,制作简单。

三.实验材料

普通眼镜(或者眼镜框),微型距离传感器,普通手机锂电池一块,升压板一块,万能充一个,微型LED灯一个,另外还有必需基本材料:细导线若干,强力胶,万用表等。

GLASS WHICH COULD PREVENT MYOPIA

1. According to the Health survey report of Chinese Ministry, the incidence of myopia among China youth up to 60%~70%,which is far more than other countries, ranking second in the world. The findings show that the reason the majority of juvenile myopia is the incorrect posture of holding pens and reading books as well as over online and watching TV. Based on this situation, we developed a kind of glasses that can prevent myopia, which solves the technical problem of sensing distance to guard against myopia. Meanwhile, it also solves the problem of traditional anti-myopia product design complexity, costly and too bulky to be not easy to carry.
2. The product has the following advantages:(1) for the users, being away from the book, keeping correct posture, protecting eyesight, achieving the effect of prevention and treatment;(2) The whole device is compact and lightweight, easy to carry;(3) the product is rechargeable, recycling, and also solves the issue of environmental pollution caused by the waste batteries, achieving the effect of environment protect. (4) Low cost, simple manufacture.

3. Experimental materials Ordinary glasses (or frame), the micro-distance sensor, an ordinary cell phone lithium battery, a boost board, a neolink charger, a miniature LED lights,.In addition to the necessary basic materials: several thin wires, super glue, multimeter etc..

Step 1: 固定锂电池

用强力胶将普通手机锂电池固定在万能充上。

Use super glue to fix the ordinary phone lithium battery on the neolink charger.

Step 2: 调节至合适电压

用导线将电池与升压板相连,调节升压板得到合适电压(距离感应器的额定电压)。

Connect the battery and boost board with wires, adjust the boost board to get the right voltage (rated voltage of the distance sensor).

Step 3: 安装距离传感器

安装距离感应器并接负载LED指示灯,(LED的工作电压需与传感器额定电压一致)。

Connect the load LED indicator to the distance sensor (The working voltage of LED should be consistent with the sensor rated voltage).

Step 4: 调节传感器距离

调节距离感应器使之感应距离为适当距离(一般为30CM)。

Adjust the distance sensor to make the induction distance appropriate (30cm generally).

Step 5: 把传感器固定于眼镜框上

将距离感应器固定在眼镜框架上。注意眼镜不要阻挡了信号源,正确安装。

Fix the distance sensor on the frame. Be aware of that the glasses should not block the signal source, and should be installed properly.

Step 6: 美化

美化:将第一、二步骤中的实验装置装在一个大小适当的塑料壳里,塑料壳最好底面镂空,以达到散热效果。

Beautification: mount the experimental apparatus of first and second step in a appropriate size plastic case. It is better to hollow the underside to achieve the effect of radiating.

Step 7: 成果展示

1、当读者距离书本较近后指示灯将一小束光射至书本上进行提示,使读者调整坐姿。

2、读者调整坐姿之后,指示灯灭,从而达到预防近视之目的。

1、When the reader get closer to the book, the indicator will emit a small beam of light to the book to promt you .
2、Far from the book, the indicating lamp the will not prompt.
