I think anxiety may bring us vision problem. More and more people are suffering from great anxiety nowadays. Even my little brother said that he felt great anxiety. He was just 10 years old at that time. he didn't want to go to school. he said that he couldn't understand what his teacher was saying. Obviously his anxiety was coming from lagging behind. Every time he suffered from great anxiety from his study, he would tell us he was seriously ill. He had some vision problems. he couldn't see the blackboard clearly. Sometimes he would tell us that he may need a pair of eyeglasses immediately. But later he would manage all the things without glasses. Although all the families laughed at him in some way, often we would call him a liar, we still tried some ways to help him reduce his great pressure and help him with his homework. But later we know that anxiety can cause vision problems.
