Abstract:
COVID-19 use causes dry eyes, fatigued eyes, increased myopia, shoulder, and back
pain. Symptoms include dry eye, vision correction, binocular visual pressure, and
precorneal tear film complaints. This project will construct a distance circuit utilising an
ultrasonic sensor for a vision care detector, a timer circuit for managing the time
duration in using electronic devices to prevent eye strain, and an analysis of the eye
strain user's usability in distance and time duration. The Arduino microcontroller
monitors the user's sitting distance from the screen and time spent on electronic
devices. This project's ultimate result is detecting the user's distance from the
computer screen; 40 cm is a reasonable distance. Every two minutes, the user's
seating distance is monitored to monitor eye movement, improving sitting posture and
preventing eye strain.
