Elementary school in the Chinese province of Hubei has made metal frames on the tables of their students in order to prevent "visual impairment". 41 percent of children in Chinese primary schools today need glasses

Elementary School has raised the bar for their students - literally.

Metal frames are placed on the table to stop the children to be too close to their book and become myopic. The position of the picture frames prevent small pupils to be too lean over his books and notebooks. The frame can also be moved forward, so that the student could lay my book on him, at the appropriate distance for reading.This idea began to implement in a Chinese school.

Today, children spend a lot of time staring at things at close range."Parents are not aware of the serious consequences of poor eyesight, but they only care about the good results of their children in school."Australian scientist Professor Ian Morgan, who has published articles on this topic in the journal Lancet, said that, while long hours in school work pressure on the eyes, exposure to sunlight may be the protective factor.

It is believed that exposure to sunlight stimulates the release of chemicals that prevent distortion of the eyeball and the occurrence of myopia.He added that daily nap, which are common in schools deprive children of Southeast Asia much daylight.The director Zhang Jianming, Zhang Lin Elementary School, is said to have metal frames against myopia installed by the City's Office against children myopia.
