1983 Study shows White People have twice as much Myopia as Black People* (26% to 13%). Also White people had 3-4 times more hyperopia (farsightedness). Now the present rate of myopia is as high as 43% - less than 30 years later. Does a near doubling of the rate of myopia make it seem like heredity is the player at large here?
No. It implies something else is the cause of myopia. Could it be the influx of tvs, laptops, computer games, worse teachers, worse diet, less exercise, less time out doors? I say so.
