For a long time, school authorities have racked their brains to find a way to prevent short-sightedness in students. And now, educational authorities in south China's Guangzhou city have come up with a new idea - presbyopic glasses, typically used to cure presbyopia for the seniors.
However, Guangzhou-based "Yangcheng Evening News" criticized this move, saying that Educational authorities should not take the risk of undertaking researches on how to prevent short-sight in students.
The article says that Guangzhou education bureau will conduct a research on presbyopic glasses without proper scientific method. They will reportedly choose 2,000 primary school students and divide them into two groups: One group will be ensured one hour of outdoor activities per day and the other group will be asked to wear presbyopic glasses at 3 diopters.

No one doubt the good intentions of the educational bureau of conducting the research. But if presbyopic glasses prove to be useless, the paper asks who will be held accountable for the consequences of the research.
In this way, the article suggests that the method to prevent short-sightedness needs to be carefully studied, and avoid to do damage to students' health.
