Methods To Solve Computer Vision Syndrome
Computer Vision Syndrome (CVS) is a complex of eye and vision problems related to near work which are experienced during or related to computer use. It is the strain on the eyes that happens when you use a computer or digital device for prolonged periods of time. There are a number of factors that determine the amount of strain your body feels as you work on a computer or other digital device.
Symptoms Of CVS
Contact lens discomfort
Causes Of CVS
Uncorrected spectacle power
Inappropriate glasses for computer use
Strain on the muscles of the eye due to work style
Decreased blink rate or tear function
Job nature and stress
Have strain at computer work.
The first step towards prevention is to be aware. Awareness of what is ideal for the eye and visual system to work comfortably is thus the first step. Get your eyes checked regularly is the second step. Here are a few points to prevent computer vision syndromes.
Adjust your viewing angle
The angle of your gaze plays a key role in CVS. For the best angle, the center of the monitor, tablet or phone should be 20 to 28 inches from your eyes and 4 to 5 inches below eye level. If you’re looking back and forth between a screen and reference materials, keep those materials where you can see them with minimal head movement.
Rest your eyes
When using a computer or device for an extended period of time, take regular breaks to prevent eye strain. Every 20 minutes, look away from your computer and look at a distant object for 20 seconds. This will give your eyes a chance to refocus. After two hours of continual computer use, rest your eyes for 15 minutes.
Letters on a screen are not as clear as letters on a printed page. Too little contrast between letters and background or glare on the screen makes your eyes work harder. The result: sensitivity to light. Position your screen to avoid glare from overhead lights or windows. Close the blinds on your windows or switch to lower-watt bulbs in your desk lamp. If you cannot change the lighting to minimize glare, buy a glare filter for your screen.
People normally blink about 18 times a minute, but computer users tend to blink only one-fourth as often. This increases the chance of developing dry eye. To reduce this risk, remind yourself to blink more often. And refresh your eyes periodically with lubricating eye drops.
Adjust your computer display settings.
Adjust the brightness of the display so it’s approximately the same as the brightness of your surrounding workstation. Adjust the text size and contrast for comfort, especially when reading or composing long documents. Most people find it more comfortable to view a computer when the eyes are looking downward. Optimally, the computer screen should be 15 to 20 degrees below eye level.
