50------60cm
The optimal distance for operating a computer should be maintained at 50 to 60 centimeters; if the screen is larger, this distance can be increased to 70 centimeters as appropriate. Too short an interval can lead to radiation damage, and it may also cause or increase myopia ； If the distance is too great, one has to stretch their arms and shoulders to reach the mouse, which can cause shoulder muscle pain over time. The ideal height for setting up a computer is such that the top of the screen is at 30 degrees below horizontal sightline, with the screen tilted upward by about 10 degrees. On one hand, this can increase the exposed surface area of the cornea, exacerbating dry eye syndrome ； On the other hand, it can reduce the strain on the neck muscles, thereby increasing the incidence of cervical spondylosis. Just focus on your posture; curl one of your arms, with the palm facing the screen and the back of the hand facing away from you (although it’s also okay to turn it the other way around). Look at your hand, keeping a distance that is sufficient to cover the screen.
It is standard to keep the eyes at a distance of 35-40 centimeters from the computer screen, and to adjust the screen so that it is 10-20 degrees lower than the line of sight; however, my distance from the screen is around 600 mm
