There is now a trend that more and more people get eye problems of certain sorts as modern civilization advances. For example, the number of eye problem sufferers increases rapidly with the emergence of computers. Computer, one of the most important achievements in human history, is one Visiclear  of the most important factors leading to various sorts of eye problems. Of which, many computer users have suffered from CVS, abbreviation for computer vision syndrome. It strikes people who use computer for long time, among either adult or children.

CVS is the results of brain’s adaptation to users’ reading habits, which is completely different from reading on paper. However, the adaptation will cause great pressure to eyes and user’s eyes become strained and their visions get declined as a result.

Though many frequent users of computer think they do not get CVS, there are some symptoms that may indicate the existence of this problem. Usually, people who feel some sort of headache, while using computers; who can not focus while reading; who feel irritation in their eyes; who feel some sort tiredness and pain physically; who get blurry vision, etc., all may have this problem. Pay more attention while using computers.

Luckily, this CVS can be prevented or slowed down by people with or without this problem. First, make sure the working environment is nice with ideal lighting, which will lessen the possibility of eye strains and pressure. Second, make sure that the computer monitor will cause less radiation, like LCD monitor. Third, if the monitor is not very nice, computer eye wear should be used. These eye wear can help protect eyes from being damaged by many harmful rays caused by the computer. But they must be prescribed for better safety. Fourth, if people do not wear computer eyeglasses, they should add some special coatings on their glasses, so as to lower the potential risks. Fifth, make sure that the distance between monitor and chairs should be within reasonable and safe range. Ultimately, relax eyes at certain intervals by looking at objects in different places.
