Computer Vision Syndrome
Computer vision syndrome (CVS) is a temporary eye vision problem resulting from focusing the eyes on a computer display for prolonged, uninterrupted periods of time.
Different problems encountered after prolonged use of computers. You can have some of these problems:
Contact lens discomfort
Neck ache and backache
Slowness in changing the focus of your eyes
Dry & Irritated eyes
Sensitivity to light
Changes in color perception
Reasons for CVS
When using the computer your blink rate decreases by a drastic 70 percent. Generally speaking means that instead of blinking an average of 14 times per minute, you are now blinking 7 times per minute.
Prevention is better than cure for CVS
If your eyes are dry or irritated, use eye drops to moisturize and lubricate
Place reference to typing materials close to the computer screens.
Visual breaks: A good rule of thumb is 20/20, 20 minutes, look 20 feet away for 20 seconds.
Avoid shifting at a location with direct blower or an A.C or for a long period in a room with low humidity
Install a glare guard, an optically coated glass anti-glare filter.
Install a screen or partition behind your computer to reduce overhead glare.
Use a non-reflective paint or coverings on the walls.
Make sure there is sufficient light to read hard copy without straining.
Use a stand for hard copy so that source documents and the computer screen are at roughly equal distance from the eyes.
If any symptoms are worse of you sight is deteriorating, make an appointment to see your eye care professional
Adjust the height of your desk or chair so the middle of the computer screen is about 20 degrees below eye level. The screen itself should be 16- 30 inches from your eyes.
Choose screens that can tilt and rotate. A keyboard that you can adjust is also helpful.
Electrostatic charge on the computer which attracts & accumulates dust particles which can cause skin rash or irritation in sensitive individuals, clean computer screen regularly
