I believe that if someone who is nearsighted were to wear glasses for farsightedness for some length of time that would result in a reduction of the nearsightedness. If you think that sounds crazy, what do glasses for nearsightedness do? They make you more nearsighted. So, glasses for farsightedness would make you less nearsighted. I think this would work for people under 25, especially children. If you are -1.75, then you have some nearsightedness. If you can usually function without glasses, you might want to try farsighted (reading) glasses for a while and see what they do. I can't do it as I am dependent on glasses, and I think I'm too old.
