S.H.
how's her blood sugar? When mine is low or high, my vision is messed up!
my son wore glasses for reading during 4th grade...again in 6th grade...& hasn't since (10th grade now). The more he used computers, the more he required glasses. All-technology classrooms meant glasses for him. Text book/computer-combined classrooms meant he was a.o.k. without glasses. Crazy, hunh?
& then that brings us to behavioral issues...& that's up to you to decide if that's what's happening. Rule out medical...& go from there. :)
