subject: Computer Glasses Are Near At Your Hand [print this page] Nowadays, computers have played an irreplaceable role in modern time. We use them to work study and entertain. We cant remember that how many hours that we have sit in the front of computers. However, long time exposure to the computer will make us suffer from some discomfort. For example, it may lead to symptoms like dry eyes, blurred vision and even headaches. These symptoms can be called Computer Vision Syndrome, short for CVS. Luckily, computer glasses will help us to deal with the situation.
Generally, wearing regular eyeglasses cant make us encounter these problems. These symptoms are mainly related with the computer users. Computer glasses are an effective tool to help us take good care of our eyes and ensure us to use computer without destroying our vision.
For computer glasses, the whole lens is positioned in such a way that it focuses at the same distance, which can effectively reduce the need to tilt the head to get better readability. According to the current market, there are several kinds of particularly designed computer glasses for us to choose.
One of the popular ones is the single vision computer glasses, which deal with the feature of the entire lens designed to see the computer monitor. Although these computer glasses are popular among a large number of people, they have some disadvantage---objects farther and closer than the computer screen appear blurred. Certainly, you can pick out depending on your real needs.
Once you spend long time sitting at the computer, you are necessary to prepare a pair of computer glasses for you. Timely protection will enable you to stay away from the CVS.
