Bottom Line: Nearsightedness (myopia) is a leading cause of visual impairment worldwide. A new study of about 4,700 Chinese schoolchildren suggests the rate of nearsightedness may be 20 percent to 30 percent each year from first grade onward. If such a frequency is confirmed with further testing, researchers suggest interventions to reduce the onset of nearsightedness, such as increasing the time spent outdoors, should be initiated in primary schools.
