From the study you linked: "A likely explanation of the inverse association between pregnancy and myopia progression is the higher exposure to outdoor activities in pregnant women during their maternal leaves. Time of outdoors physical activity of 6.9 vs 5.2 h per week (P=0.002) in pregnant woman compared to non-pregnant woman." Outdoor activities - the same thing as in the Wired article that's noted to slow down myopia progression. I don't think this study supports what you think it supports. Also myopia didn't reverse, the rate of increase merely slowed down in the pregnant women.
