How to place a computer to avoid dry eye

The height of the computer is best placed with the upper end of the screen located at 30 degrees downward from the horizontal line of sight, and the screen is tilted slightly 10 degrees upward.

This can reduce the exposed area of the cornea and reduce dry eye; replacement can relieve muscle tension and reduce the incidence of cervical spondylosis.

  Office workers staring at the computer every day. If they do not pay attention to the self-protection of the eyes, they will alternately change eye fatigue, which will seriously affect the whole body and cause “computer fatigue syndrome”.

In addition to improving the screen quality of the computer and adopting various self-care methods, the placement of the computer, the adjustment of tables and chairs, and the sitting posture all require attention.

  The optimal distance for operating the computer should be maintained at 50 cm-60 cm. If the screen size is appropriate, the distance can be extended to 70 cm as appropriate.

If the distance is too short, it is easy to be harmed by radiation, and it is easy to cause myopia or deepen myopia; while if the distance is too long, it is necessary to extend the shoulder arm to move the mouse. A long time will cause shoulder muscle pain.

  The height of the seat is best to be naturally bent at 90 degrees or lean forward slightly with the feet flat on the ground.

If the seat is too high, the legs will drape, which will compress the blood circulation; while if the seat is too low, the legs will buckle and compress the internal organs, which will affect the physiological function.

The back should lean forward to straighten the spine, otherwise long-term arching of the waist or even compression of the internal organs will cause people to appear hump prematurely.

  It is recommended that everyone is best to sit in front of the screen, do not tilt the computer sideways, otherwise the adjustment of the eyes will be unbalanced for a long time.

Not only that, but also caused neck, waist, shoulders, wrists excessive bending and strain.

It should also be noted that the work environment is well ventilated, the light is reasonable, and the humidity is moderate.

There should be a certain amount of space at the back of the computer so that when looking at the gap between the computers, there is room for expansion.
