This is also what I came up with, with my own experience. Basically, everytime I get prescription glasses for myopia, my myopia gets worse a few months later. What baffles me is that none of the professional I've seen (I think 2 ophtalmologists, 1 orthoptist, 1 optician) told me about that Now I feel truly bitter about the eyes professionals, even though I'm sure they are good at catching defunct eyes, I feel like they don't know how what to advise you, when it gets worse and worse.
