Computer vision syndrome (CVS) is a temporary condition resulting from focusing the eyes on a computer display for protracted, Long uninterrupted periods of time.

This is really a serious problem for young people especially for those whose work can’t do without computer like software developing, online marketing, online shop managing, etc.

However, as the window of soul, we have no reason not to protect our eyes! Needless to say, the most important is to reduce the time staring at computer and other LED screens.

Some symptoms of CVS include headaches, blurred vision, neck pain, redness in the eyes, fatigue, eye strain, dry eyes, irritated eyes, double vision, vertigo/dizziness,  polyopia, and difficulty refocusing the eyes. These symptoms can be  further aggravated by improper lighting conditions or bright overhead lighting) or air moving past the eyes (e.g. overhead vents, direct air from a fan).


Eye problems caused by prolonged computer use includes:

  • Eye irritation (Dry eyes, itchy eyes, red eyes)
  • Blurred vision
  • Headaches
  • Backaches
  • Neck aches
  • Muscle fatigue

Although CVS has not been found to cause any permanent damage to the eyes, its painful symptoms can affect performance at work and at home. Eye health professionals, though, have found several ways to prevent CVS from affecting computer users.


The Vision Council, an organization representing the optical industry, recently released a 16-page online document that explains the problems associated with eye strain and makes recommendations for how to combat it.

Here is the summary of the report.

Adjust external factors:

  • Reduce glare. Adjust the brightness of your screen by checking the control settings on your digital device. Glare reduction filters are also available and can easily attach to computer screens.
  • Clean your screen. Frequently dust and wipe digital screens to help reduce glare.
  • Dim your surrounding lighting. Lessen the amount of overhead and surrounding light that is competing with your device’s screen. Dim inside lights and try to avoid outside areas of intense brightness. This can help to reduce glare and strain.
  • Keep your distance. Position your device so there is sufficient distance between your eyes and the screen.

1) For computers, try sitting in your chair and extending your arm. Your palm should be able to rest comfortably on the monitor (as if you’re high-fiving the screen).

2)For hand-held devices, try to keep the device a safe distance from your eyes and hold it just below eye level.

  • Adjust your screen. Digital screens should always be directly in front of your face and slightly below eye level. Do not tilt a computer monitor.
  • Increase text size. Bump up text size to help better define the content on your screen.

Remember Internal factors:

  • Blink more often. Starring at a digital screen can affect the amount of times you blink, causing eyes to dry. Remind yourself to blink more often, which will also help to refocus your eyes.
  • Take a 20-20-20 break. Even short breaks can make a huge difference. Every 20 minutes, take a 20-second break and look at something 20 feet away.
