I wear glasses, putting them on mostly for close up work or when I'm really tired. The glasses do tend to wander away, and it seems I'm forever cleaning all the smudges off of them. I'm not sure how it happens, I clean them until they're pristine and 15 minutes later, they're totally smudged.
Picture a night in the kitchen while preparing dinner.
Partner in Grime: I think I know how your glasses get so smudged.
Partner in Grime: I just found them lens side down in the butter.
That might explain it.
So get out your glasses for a weekday morning recipe, sure to keep everyone close by.
