Are you aware that a major part of the Indian population is struggling with Computer Vision Syndrome? Headache, eye strain, blurred vision, and dryness in eyes are some of the symptoms of CVS. Blame it on the prolonged hours spent on computer screens, tablets or smartphones. People especially working in the service sector or performing desk jobs often tend to develop CVS. If you consult any privileged eye care centre like Centre for Sight, you may come across the fact that such centres show a lot of concern on an issue like CVS.
So much about Computer Vision Syndrome. What is it after all?Computer vision syndrome (CVS) results from straining your eyes by working on PC, Tablet, Mobile, or any other second screen for several hours without any break. The eye muscles get strained thereafter. What adds to the misery is the lack of adequate sleep. If people had an uninterrupted sleep of seven to eight hours, they would have managed to recover from the strained eye muscles. Some common symptoms associated with CVS are:
- Eye pain
- Blurred vision
- Non-ocular issues such as neck and shoulder pain
Causes of Computer Vision Syndrome (CVS)
- Blinking eyes is an essential part of eye health. However, when a person stares at a bright screen, the rate of eye blinking is reduced. It leads to dry eyes which cause redness of eyes, eye pain, headache, etc.
- Our eyes are not designed for prolonged nearby focus which results in convergence spasm of the small eye muscles.
- Incorrect sitting posture or positioning of the computer screen also causes significant problems.
- CVS is also caused by not wearing glasses or contact lenses of the right prescription. If a person has a pre-existing eye disorder such as eye dryness then they are prone to CVS.
