Read in Hindi

Do you experience dry, burning eyes? Headaches that just won’t go away? Are you sick of staring at the computer screen? Well you could be suffering from what the doctors call Computer Vision Syndrome (CVS).  CVS is a temporary condition caused by using a computer or staring at a screen for a long period of time. In this day and age where most people work on computers for long hours, it’s a condition that ails most of the urban workforce. We talked to Dr Prakash Nayak, an expert ophthalmologist about the issue.

Computer vision syndrome (CVS) is a condition which is ever-present in today’s urban population who spend all days on their laptops or computers. Viewing a computer screen often makes the eyes work harder than normal. The unique characteristics and high visual demands of working on computers make individuals susceptible to various vision related conditions.

Different distances and angles also result in aggravating the issue. Even minor vision problems can turn into major ones due to protracted computer use. Even people who have an eyeglass or contact lens prescription may find it’s not suitable for the specific viewing distances of their computer screen.

In fact along with eye conditions, the posture we use laptops in can result in muscle spasms or pain in the neck, shoulder or back.
