About 25-30 percent of students in Vietnam suffer from refraction errors with their eyesight, according to a survey conducted by the ophthalmological sector.
In Hanoi and Ho Chi Minh City, the rate fluctuates between 30-60 percent.
Ophthalmological experts said that almost all Vietnamese students with the errors did not have them detected in time. They noted that people who use glasses, but do not change their lenses to match the development of their eyesight, are also affected.
Heredity factors are considered the main reason for the issue.
According to experts, in order to improve eyesight, it is necessary to improve illumination in classrooms and reduce the amount of time spent watching TV and playing computer games, while increasing outdoor activities and eating food rich in Vitamins A and E.
Statistics from the Wold Health Organisation show that more than 2.5 billion people, or 20 percent of the world’s population, have developed refraction in their eyes, and Asia records great number of people with the complaint.-VNA
