It’s so true what you say about dependence on glasses. I can’t take off my glasses without being crippled. A low myope like you with dirty or broken glasses can usually go, meh, whatever, and just take them off. Beyond -2, this becomes a real problem. Beyond -3, well… better try to use the glasses anyway, because there’s not much to see without them.
Good idea to shoot for a goal in 2019! I’ll make mine to pass the -3 milestone on all measures. Last year, I mostly equalized, enabling me to comfortably read books without glasses. After passing -3, I could start doing some desk tasks without glasses. I like the idea of restoring the ability to do another kind of thing without glasses every year, dropping the dependence bit by bit.
I’d love to know more details about your past story. You must have a lot of glasses that you grew out of!
