If he is looking over his glasses, unless he has his glasses pulled down intentionally, then his head is in the WRONG POSITION.

The shooter's head should NOT be leaned forward. You do NOT lower your eye to your sight, you raise the bow to your eye. Dropping your head puts your neck and back in a weak position that promotes instability in your shot, and looking out of the top, bottom, or side of your eye socket (i.e. your eye is not close to centered) hinders your visual acuity.

I know you've mentioned this in other threads, but did you end up getting 2 bows, or only one for both of you to shoot?
