What is Computer Vision Syndrome :
Staring at a computer monitor for hours on end has become a part of the modern workday. And inevitably, all of that staring can put a real strain on your eyes. Computer Vision Syndrome describes a group of eye and vision related problems that result from prolonged computer use. Many individuals experience eye discomfort and vision problems when viewing a computer screen for extended periods. The level of discomfort appears to increase with the amount of computer use.
Research shows computer eye problems are common. Somewhere between 50% and 90% of people who work at a computer screen have at least some symptoms of eye trouble. Computer vision syndrome is similar to carpal tunnel syndrome and other repetitive stress injuries at work. It occurs when you’re carrying out the same motion over and over again. Just like those other repetitive stress injuries, computer vision syndrome can get worse the longer you continue the activity.
What Symptoms Are Part of Computer Vision Syndrome:
If you have computer vision syndrome, you may experience some or all of these symptoms:
* Blurred vision
* Double vision
* Dry, red eyes
* Eye irritation
* Neck or back pain
If these symptoms are not treated, they can have a real effect on your work performance.
Causes of Computer Vision Syndrome:
• Poor lighting
• Glare on the computer screen
• Improper viewing distances
• Poor seating posture
• Uncorrected vision problems
• A combination of these factors
How is Computer Vision Syndrome Treated:
Solutions to computer-related vision problems are varied. However, CVS can usually be alleviated by obtaining regular eye care and making changes in how you view the computer screen.
1. Have your eye muscles tested once a year.
2. If you use contact lens, take care not to over wear the lenses.
3. Don’t be too close or too far from the monitor. Maintain a distance of 20-24(18-28) inches from the eye to display.
4. Adjust the monitor’s brightness, contrast and flicker rate as appropriate.
5. Use glasses with an anti-reflective coating.
6. Use indirect lighting and eliminate exterior light and reflections by closing drapes or blinds.
7. Take a break every 20 minutes and look outside your window or at a distant object for 20 seconds.
8. Make top of the monitor slightly farther from the eyes than the bottom of the monitor.
9. Make sure that use dark letters in a light background.
10. Blink at least 15 times per minute while working on the computer.
