Nowadays, computer games are very popular and in great demand among children and adolescents. Computer games are divided into many groups: logic, shooting, for girls, adventure, detective. But what is the use of computer games? I think games that develop thinking, logic, memory, and also detective games will be useful, as they develop resourcefulness, logic, and also adventure games. These are exactly the games that will bring both benefit and pleasure. But some games are created only for entertainment, in which there is nothing instructive, and even are cruel, which develop anger in the child to the world around him. And the main harm that unites computer games is a visual impairment. So play at the computer should be in moderation. And breathe more fresh air.
