Computer work related eyestrain can be experienced as burning, tightness, sharp pains, dull pains, watering, blurring, double vision, headaches, and other sensations, depending on the person. In addition, your  eyesight will get worse over time - this unavoidable development is known as Presbyopia.

Here are some aspects that you should take into account in your working place, to help your eyes survive longer:

  • Eye-to-screen distance: at least 25", preferably more.
  • Vertical location: viewing area of the monitor between 15° and 50° below horizontal eye level.
  • Monitor tilt: top of the monitor slightly farther from the eyes than the bottom of the monitor.
  • Lighting: ceiling suspended, indirect lighting. Use blinds and shades to control outside light.
  • Screen colors: dark letters on a light background.

How do you set up a computer workstation? Do you buy monitor risers or remove the CPU from beneath the monitor. Will even lower monitor positions cause neck strain? Can you get away with tipping the monitor down to avoid glare or should you invest in indirect lighting? How about viewing distance? 16 inches? 25 inches? Or even farther? Does screen color make a difference? Can ergonomic workstations improve work performance?
