Thanks for posting. It is suprising how rapid the increase in near sightedness has been in China and other places. One factor could be, once you start wearing glasses, your near sightedness vision gets worse. Perhaps many people who were nearsighted in the past were only slightly so, not enough to impact their daily activities. Nowdays, kids with nearsighted vision are caught early and givdnn glasses, before their eyes are fully formed, cusing their vision to get worse. That might explain the very rapid rise in China, as it's prosperity increased. In the West, there was often a stigma in the past about wearing glasses (old saying "men don't make passes at girls with glasses)
