Prevent Nearsighted Device

Description: Prevent Nearsighted Device can detect the distance between the user's face and computer. If the distance less than 50cm, then the screen will become blurred until the user keeps his/her eyes away from the computer.

Nowadays many children get nearsighted, it is because when they use the computer, they cannot keep the distance to the computer. Prevent Nearsighted Device is made by Arduino Uno, ultrasonic sensor, relay and switchable glass. It can detect the distance between the user's face and computer via the ultrasonic sensor. If the distance is less than 50cm, then Arduino Uno will switch off the relay, the switchable glass will become blurred until the user keeps his/her eyes away from the computer. Ex numquam veritatis debitis minima quo error quam eos dolorum quidem perferendis. Quos repellat dignissimos minus, eveniet nam voluptatibus molestias omnis reiciendis perspiciatis illum hic magni iste, velit aperiam quis.
