Diagnosis and Treatment of Computer Vision Syndrome

The severity and length of computer vision syndrome symptoms depends on how long you stare at the computer, your posture, lighting, glare, the angle of the monitor, and whether or not you have other diagnosed or undiagnosed vision problems. If you already suffer from astigmatism, farsightedness, presbyopia, aging eyes, and/or diabetic eye problems, your computer vision symptoms may worsen. This can even be the case if you already have prescription contacts or glasses. Many regular eyeglasses and contact lenses are not designed to deflect the problems caused by computer screens. There are many things we can suggest to cut down on computer eye strain problems:

Computer Setup
  • Adjust your monitor so that it is about 15-20 degrees lower than your eye level when seated between 20-28 inches away from the screen. Reference materials can be placed on a document holder between the monitor and keyboard, or to the side, but positioned for as little head movement as possible.
  • Invest in an anti-glare screen for your monitor to help reduce glare from surrounding lights. Be sure to sit and work with proper posture.
  • Adjust Lighting—If you can, reposition any lighting (or your computer) to minimize glare and use natural lighting whenever possible.
  • Eye Rest and Blinking Breaks — Every 20 minutes during your work, look away toward a distant point for 20 seconds to refocus your eyes, and give them a 15-minute break after each 2-hour computer session. Also remember to blink more frequently to keep your eyes moist.

With a combination of the proper optometry care and self-care, you can minimize computer eye syndrome and other modern-day vision problems. Contact us for an appointment today.

Eye Doctor
  • How many hours/day am I on the computer?
  • What is the lighting in my workplace?
  • What symptoms am I experiencing?
  • What medications am I taking?
  • How far are my eyes from the computer screen?
  • Work tasks--data entry vs word processing?

  • Get an eye exam. If you wear glasses, make sure they meet the demands of your computer.
  • Your blink rates decreases by about half when you work on your computer.
  • So remind yourself to blink a lot and use lots of artificial tears.
  • Make sure your monitor size equals your workload. A 15-inch monitor is fine for word-processing tasks. A 17/19-inch monitor is best if you work several documents at once or with large spreadsheets.
  • Place the computer screen in front of you if you work mainly from it, and if you work mainly with paper sources, place them in front and the terminal to the side.
  • The screen should be at least 26-inches away from you and the top of the screen 2 to 3-inches below eye level.
  • Use shades and blinds on windows to control glare and reflections.
  • Clean your computer screen regularly to decrease dust and fingerprints.
  • Take breaks--for a moderate workload take a fifteen minute break every two hours--for heavy workloads take a fifteen minute break every hour.
  • Close your eyes or focus your eyes at a distance.
