What is Computer vision Syndrome?
Computer Vision Syndrome (CVS) is a series of visionary problems that can be caused by constant computer use. This is usually a temporary disorder caused by staring at a computer monitor for uninterrupted, long periods of time.
Many computer users have vision problems and discomfort in their eyes when looking at a computer monitor for a long time. The degree of discomfort usually depends on the eyesight and appears to increase with the level of computer use.
Typical symptoms associated with CVS are headache, eye strain, dry or red eyes, blurred vision, dizziness, shoulder and neck pain, etc.
Computer vision syndrome is also known as terminal disease.
According to the National Institute of Occupational Safety and Health, CVS can affect approximately 90% of computer users who spend three hours or more per day in front of a computer screen.
Most of the symptoms of the visual impairment are temporary and may decrease after you stop using your computer. However, many people may suffer from impaired vision, including blurred distance vision, even after they finish using the computer.
The reasons for these symptoms can be attributed to the following causes:
- Bad light
- Excessive brightness on the computer monitor
- Inappropriate viewing distances
- Wrong sitting position
- Uncorrected vision problems
- A mixture of the above factors
Here are some precautions that can be taken to minimize the effects of CVS:
Blink your eyes. It helps wash your eyes with natural therapeutic tears.
Try to stare at something at least 20 feet away for 20 seconds every 20 minutes.
Keep the bright light head as low as possible. Use blinds and use an anti-glare screen protector. Position the computer monitor so that the
Reflections from ceiling lights or windows are minimal.
Hold the computer monitor at least 20 inches from your eyes. Adjust the brightness and contrast to suit the eyes.
Bring the computer monitor down slightly.
Carry computer specifications that are specifically tailored to these problems.
