First, congradlations on what you lost, geat job!! I myself was pretty much in same boat, except I went the weight watchers way. Lost almost 75lbs. When pre-bow season came around, dusted off the bow, reset it for 65lb draw. Let me tell you I almost ripped my right shoulder. I spoke to a trainer, he claims sometimes many people focus on losing weight by combination if diet and cardio, leaving out the other muscles. The result is you can lose almost %50 of your upper muscle mass. After a about two weeks hard on the bowflex, I was able to get my strength back.
I hear you about the glasses, it's a pain, but tolerable..
Good luck
