I would make two more general points.  First, you could very easily argue that eyeglasses make (many not all) teenage girls feel worse about their body image.  Lots of things will.  Automobiles.  Parties.  Clothes shops.  Such costs are not zero, but they have to be put in perspective.

Second, the lives of teenage girls are messy and complex. Anything that plays a noticeable role in said lives also will have effects that are messy and complex. Deal with it. The same used to be true of the (old-fashioned) telephone as well, not to mention birth control pills and automobiles.
