Wife got the more 'spensive flexible (non-breakable) frames and he got to pick out the ones he wanted. So, I think he'll be okay.
Wife is feeling guilty because this is one of the things that could happen with prematurity. I told her we are fortunate that this is ~all~ we've had to deal with. The asthma isn't really even an issue anymore.
Yeah, glasses are no biggie. He'll adjust, hopefully quickly. Just convince him to take up engineering or something when he gets that old, everyone else will wear them too.
