The personal computer is the most innovative development of the modern century. Traditional methods of research and communications are replaced by a pc. We almost depend on personal computers for every work we do. We communicate, learn, read and do every other activity using personal computers. This demands sitting in front of the machine for long hours. Hence, a large number of people are getting affected with a vision disorder known as the CVS or the Computer Vision Syndrome. This disorder makes our vision blurry by long hour of usage of the PC. Special glasses are developed that are recommended to use while one works in a PC.
However, it is not advisable to people having lenses for near vision and distance vision problems to wear similar computer glasses. This will not serve the purpose. The main reason behind this is that the filed of vision for near and distance vision works are different. The computer glasses are exclusively designed to be used while working in front of the PC. This reduces strain from eyes leading to a comfortable eye sight.
The kind of computer glasses that suits you depends on the reasons for what you want the glasses. If PC usage is the sole reason then computer glasses made specifically for this reason is only perfect. These computer glasses are cheap and can be used all the time while you sit in front of the PC. However, if you wish to correct your eye sight then a visit to the doctor is a good idea. One must then buy glasses as advised by the professional specialist.
