Suggestions on where to find reasonably priced children's glasses? (7 year old, with severe strabismus. Progressives required and thus we can't order from online due to the measurements she would require). We went to lens crafters yesterday and they no longer offer the half off kids deal, and considering she needs new glasses nearly every year, if not more often, $500++ for one set (with only 200 every two years cover by our insurance) isn't in our ballpark. Please accept this bug sticker as a token of appreciation, thanks
