Is Computer Bad for Eyes? | Computer Vision Syndrome

computer vision syndrome

Since the year of 2009, research indicates that computer use has taken the place of radio as the No. 2 media activity. The increased use of computers has reflected on the development of visual discomfort and related symptoms occurring in relation to computer use.

Computer Vision Syndrome or CVS refers to a complex of eye and vision problems experienced by computer users. Patients are usually complaints of eyestrain, ocular discomfort, headache, dry eye, blurring at near and double vision. Those who spend more than 4 h per day working on computer tasks experience much higher incidence, severity, and duration of computer-related symptoms. For presbyopic (“lao hua”) computer users, neck and back pain symptoms are a significant part of computer vision syndrome.

Why are we having Computer Vision Syndrome?

To understand this, we need to know that our eye is comprises of natural lens called crystalline lens. When we are looking at near, our crystalline lens is actually changes shape to become more curved for us to focus at near. In order to do so, our eye muscles need to exert extra forces to allow this change in the curvature of our crystalline lens. As a result of long hour’s computer usage, our eye muscles become more and more tired. Eventually, this eye muscle fatigue may cause us to have Computer Vision Syndrome.

How can we prevent or reduce this type of discomfort?
