Eye fatigue eliminator based on 555 timer
Source: InternetPublisher:明天见 Updated: 2021/09/15
If the eye distance is artificially adjusted periodically, the eye muscles will regain elasticity, which will not only eliminate fatigue but also prevent myopia and aging. This is entirely possible using electronic circuits. The picture below is an example, it only uses a 555 and a few resistors.
When you turn on this instrument when your eyes feel tired after reading for a long time, the LED on the instrument will flash continuously. According to the design in the picture, in one cycle, the diode will light up for 2 seconds and then turn off for 6 seconds. At this time, if you hold the instrument in your hand, at a clear visual distance from your eyes, and look as far away as possible with your eyes, when the diode suddenly flashes, your eyes will naturally focus on this flash point, and the flash will disappear after two seconds. If you stare into the distance again, repeating this process will quickly eliminate fatigue. It also has a certain effect on people with pseudomyopia and recent aging.
