Why are more and more children getting short-sighted?
It is reported that the rate of myopia of Chinese students is ranked as the highest in the world.
The causes of myopia are complicated. Firstly, too much homework leads to the lack of time for exercise and a good sleep. Long time of studying makes it difficult to refresh eyesight. Secondly, medical research shows genetic factors also contribute to poor eyesight. In addition, many students don¡¯t form good eye care habits. For example, when reading, some students hold books too close to their eyes.
Realizing the reasons of this result, it¡¯s time for us to take measures to protect eyesight. I think the most important is to encourage students to engage in more outdoor activities and create a vision-friendly studying environment.
