Introduction: 距离传感式防近视眼镜 TEH GLASS WHICH COULD PREVENT MYOPIA
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
Use super glue to fix the ordinary phone lithium battery on the neolink charger.
Step 2: 调节至合适电压
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
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
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
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
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、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.
