I remember the day that I got my first pair of glasses. I had NO IDEA that it was possible to see leaves from across the street. What a revelation. The world was suddenly shinny and new! Even now, I swear that I actually hear better with my glasses on. Chris, just an idea. If you find that his prescription hasn't changed or has only changed a little bit, you could order a new pair of the same frames he currently has, along with his new pair. Have his current lenses put in the new frames. That way he could have a spare pair. Everyone who is dependent on glasses should have a spare if it is at all possible.
