摘　　要：为解决青少年视力下降问题,设计了改善和提高视力的智能仪器。该仪器以眼睛的生理特点为研究基础,结合计算控制技术和双色LED(Light Emitting Diode)显示技术,采用了高性能的stm32f103zet6微处理器控制LED显示和人机交互系统,并采用RLE(Run Length Encoding)图像压缩技术,使图形的显示更灵活多变、丰富多彩。测试者通过操作平台(语音提示和液晶显示),用眼观察LED屏显示的各种训练图形调节眼睛的紧张状态,缓解视力疲劳。测试结果表明,经过一段时间的仪器治疗,学生的视力普遍得到了提高,效果显著。In order to solve a common problem of vision drop in teenagers,we design an intelligent instrument for improving vision,which is based on the Physiological characteristics of the eye. The instrument applies computer control technology and dual color LED（ Light Emitting Diode） display technology,and uses stm32f103zet6 microprocessor to control LED display screen and man-machine system,and uses RLE（ Run Length Encoding）image compression technology to make display flexible,rich and colorful. The tester uses the operating platform（ voice prompts and liquid crystal display） to observe various types of training graphics,which can adjust the tension of the eye and relieve vision fatigue. After a period of treatment,the test results show that the students＇ eyesight is generally improved,and the effect is remarkable.
