However, benefits described above are only one aspect of the wide computer use by the public. There is no denying that computers can increase productivity for companies and enrich ordinary folks’ daily lives. Yet a negative factor that associated with eye health is always neglected. It is common for computer users to stare at the monitors for long stretches. They usually spend consecutively several hours in front of a computer screen without any break. In some cases, computer work does require people to spend a couple of hours with careful focus.
The problem is that this kind of hours of work can cause a lot of stress on the eyes, leading to eyestrain, fatigue and even blurriness. These problems can be more serious for wearers of contact lenses. Since contact lenses need regular and frequently eye blinking, long time of eye staring can cause dry eye quite easily. Without enough eyes blinking, contact lenses could never maintain normal moisture. There are other problems associated with excessive computer work, such as neck or back pain, eye irritation and so on. A formal term “computer vision syndrome (CVS)”is commonly used to describe these conditions.
Computer glasses are the right solution to CVS. Performing as a kind of task-related glasses, computer eyeglasses have been created to be worn specifically for long time of computer work. With the help of these glasses, computer users can perform tasks in front of computer monitors for more hours without suffering symptoms of CVS.
