There's no shortage of studies on the subject, as a quick search of Google Scholar will show. There is even causal evidence from interventional studies showing that going outdoors reduces the prevalence and severity of myopia in schoolchildren.
This topic was of particular interest to the governments of Korea, Japan, and China a while back, as their rates of myopia are in the high 90% range; I believe it was their funded research that led to the development of interventions like peripheral defocus lenses, that would slow the progression of nearsightedness in children. Alas, about twenty years too late for me.
