Personal computers have firmly entered the life of a modern person and are an integral tool for work or entertainment.. However, sitting in front of a monitor for a long time can have a bad effect on the eyesight of many people, notes BestGlobalInfo..

In this regard, scientists from the University of Texas have developed a method " Its essence is simple: a person who is at the computer for a long time should take a 20-second break every 20 minutes, during which it is necessary to examine various objects located at a distance of 20 feet (about 6 meters). In this case, you should blink at least 20 times..

As you know, a person sitting at a computer monitor blinks much less, as a result of which the mucous membrane is not sufficiently moistened and “dry eye” syndrome may develop.. In addition to dry and tired eyes, this exercise will also help prevent headaches, as well as pain in the neck and joints..

American scientists have no doubts about the effectiveness of the method they have developed and recommend using it not only for active PC users, but also for all those who want to preserve their eyesight for a long time..
