i just curious as to how much you guys study for and whether you wear glasses or not and if you do how strong they are.do you think that how long you study for/how smart you are links with bad sight?
for me,i have quite strong lenses,-3 but i don't study that much,maybe 1-2 hours and i'm not that smart.
