Lots of adolescents have such experience: after several days of constantly watching TV and playing computer games, their eyesight become much worse than before and even get myopia. But for those who could distribute certain time spending on watching objects beyond and relaxing eyes other than indulging in TV and computers, their eyesight would not worsen dramatically. From the experiences above, we can get that using eyes are just like using batteries in the electric torch. If you use it for a short while every now and then, the battery could enjoy a long life span. However, if you overuse it for a long time for once, the battery would be used up due to the excessive exhaustion. In the same way, the longer you watch the near objects, the easier you will get myopia.
Here are some tips for you to reference.
Try to control the time spent on watching the near objects everyday. It is better to limit the time within six hours.
Try to choose listening in place of reading in any possible occasions so as to lessen the pressure of eyes on watching near objects.
The classroom students study in should be bright. The desks and the blackboard in the classroom should not have strong reflection of light. And the classroom should also be equipped with low and large windows on each side. The standard of a proper position of the windows in the classroom is that any student in anywhere is able to see the sight outside the windows. What’s more, students should be allowed to exchange their seats with each other at a fixed interval.
The desk for children to study at home should be placed behind the windows without any shelter. The reading lamp should be placed in the left side on the desk, and the light of the lamp should be soft. If you use the incandescent lamp, the power would be better to be limited in the range of 25W to 40W. Never place the lamp in the position where it could radiate straight towards your eyes.
When you are using computer, the distance between your eyes and the screen of the computer should be more than 60 centimeters if your computer is 35 centimeters long. While for the computer with a length of 38 centimeters, the distance should not be less than 70 centimeters. Besides, you should keep a correct sitting habit.
Change the way of playing computer games. Try not to play games which you must spend a long time on watching the screen near. Nowadays, children tend to find indoor entertainments, such as playing toys by themselves, playing computer games and watching TV. Most of them seldom get away from the environment where they have to watch near objects for a long time. Therefore, parents and teachers should encourage children to do sports in the open air.
Form a good eating habit. You’d better mix all sorts of nutrition in your diet. Avoid the deficiency of trace elements, such as chrome, calcium, etc.
When the myopia sufferers are choosing their spouse, they should try to find someone without myopia problem so as to reduce the probability of the myopia in their kids.
Therefore, as to prevent myopia, we must get the knowledge of how to save the battery in eyes. And I hope tips listed above will help you in the journey of fighting against myopia.
