Computer Vision Syndrome

CVS (computer vision syndrome)  is a term used to describe a collection of symptoms caused by prolonged computer use.


What causes CVS?

The eyes can easily focus on printed material and images with well-defined edges that are strongly contrasted against their backgrounds. However, words and images on a computer screen do not have well-defined edges. The constant struggle to focus leads to fatigue and tired, burning eyes. Many people try to compensate for uncomfortable vision symptoms by leaning forward or by tipping their head to look through the bottom portion of their glasses. These actions can result in a sore neck, sore shoulders and a sore back.

You can experience CVS even if you have perfect distance vision and don’t need any glasses. And remember that having even a small uncorrected prescription or imbalance between your eyes, it will aggravate CVS.

Treatment of computer vision syndrome

Computer glasses are prescription glasses specially designed to allow patients to work comfortably on a computer. Computer work involves focusing the eyes at a close distance. Contact lens wearers may even need to wear glasses over their contacts while using the computer.
