It's not really odd. My son is 11 and sleeps in his glasses...as well as the clothes he wore that day. It would be odd if he took them off.
For that matter, have we ever seen Sheldon *out* of his glasses? You'd think I'd know...but I genuinely can't recall after all these years. My strong guess is "no," but I may be wrong.
If you do know of such strip in the archives, then by all means share the link in the comments! I'm just as curious as everyone else! :)
