prescription glasses? My son (15 months) likes to grab my glasses off my face and put them on himself. He doesn't wear them for any length of time, but I was wondering if it could be damaging to let him look through the lenses of my prescription glasses. I think my mom told me this years ago when I was a child, but to this day I wonder if she just told me that to get me to leave her glasses alone! Does anyone have any resources to support this claim?
