防止近视在经济高速发展的今天显得尤其重要。为满足便携式设备小型化的需要,该文介绍了一种耳麦式防近视仪。此近视仪根据红外测距原理,而且还根据光电传感器的应用,增加了补充光源的效果。文中给出了耳麦式防近视仪的详细设计方案以及实验结果。实验结果完全可以说明红外测距在近视方面的应用。
Prevention of myopia in the rapid economic development today is particularly important. In order to meet the needs of miniaturization of portable devices, this article introduces a headphone type anti-myopia device. This myopia based on infrared ranging principle, but also based on the application of photoelectric sensors, an increase of the effect of additional light source. The article gives a detailed design of the head-mounted anti-myopia and experimental results. The experimental results can fully explain the application of infrared ranging in myopia.
