I have been waring glasses since I was 9, my eyes kept getting worse about every 6 months, they eye dr told me if I got contacts it would slow it down, got them my last year of high school. It worked for a time then I was given a precision from my family dr for something not related and guess what the side affect was. It caused my eyes not to focus when I looked down to read and up. Now I have progressive glasses and I still have to take my glasses off when doing very close work. Still don't see as well as I think I should but it is what it is.
