Computer Vision Syndrome (CVS)
What is Computer Vision Syndrome (CVS) ?
Computer vision syndrome (CVS) is strain on the eyes that happens when you use a computer or digital device for prolonged periods of time. Anyone who has spent a few hours on the computer has probably felt some of the effects of prolonged use of the computer or other digital technology. The discomfort it causes can be minimized by following a few simple practices.
Symptoms
Your eye care professional can diagnose computer vision syndrome through an eye exam, with special attention paid to how the eye works and responds at computer distance.
You may have experienced at least one of the common symptoms of computer vision syndrome which include:
- Eyestrain
- Headaches
- Blurred vision
- Dry eyes
- Neck and shoulder pain
These symptoms may be caused by other factors such as uncorrected vision needs, glare, poor lighting, and improper posture.
Causes
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, including lighting in the room, distance from the screen, glare on the screen, seating posture, and the angle of your head – not to mention any existing vision problems you may have. One or all of these may combine to cause an uncomfortable amount of strain on your eyes.
