Abstract: Vision decline has brought a great impact on many people’s daily life. To this end, the design of a portable vision self-detector has an important role in relieving visual fatigue and improving eye health. The design uses the combination of electronics, information recognition, liquid crystal display (LCD) displaying, infrared remote control, SD card storage and other technologies, and uses Keil MDK5 software to realize the control connection of each module through C language programming. The user controls the infrared remote control to distinguish the direction of the icon “E”, which meets the needs of visual acuity test from 4.0 to 5.2. Meanwhile, the visual acuity detector is also equipped with color blindness detection function. The design size of this device is 22 cm×13 cm×6 cm, which can realize the function of user’s independent vision detection. The detector is practical, real-time and portable, with faster processing speed and more accurate detection results. The design of this device can better bring convenience to users and has a good development prospect.
