This topic comes from Hunan Liangshi Jia Biotechnology Co., Ltd., aiming at redesigning the appearance and interactive interface of a fast vision measuring instrument. In recent years, primary and secondary school students due to excessive use of eyes inside and outside the class, eye hygiene, China's children and adolescents myopia rate remains high, especially with the popularity of smartphones, tablets and televisions, the new crown epidemic under the vigorous development of online learning, youth myopia problem is becoming more and more serious, myopia prevention and control is imminent.

Vision protection must first test vision. Vision refers to the ability of the vision system to distinguish images. my country uses the international eye chart and standard logarithmic eye chart to test vision. However, traditional vision detection methods are not convenient to use, and the current market vision detection instruments are expensive and complicated to operate, which is not conducive to the smooth realization of vision detection.

Therefore, the design of a low-cost and easy-to-operate self-service vision detection instrument is helpful to popularize the whole people to detect their own vision and pay attention to their own vision, which is of great significance to alleviate the current serious vision problems in our country. This product is an intelligent device for autonomous vision detection.

The user performs identity recognition by brushing the ID card, detects vision by observing the optical design visual chart projection inside the device, and judges the observation results through the operation of the hand device, thereby detecting the vision results.
