My experience....
When I took the OPT EAD, I weared glasses. It was OK. When I took I485, EAD and AP, I did not wear glassed. Because on the Photo requirement my lawyer gave me, there are two lines of hand-writen words- no glasses, no earings.
BTW, why do you make it such a big deal not to wear glasses?! Just take them off! You may look a little bit ugly without glasses, but nobody will look at your pic on GC.
