Ive bought cheap (under $%) non-prescription reading glasses at a local drug store. If they retail for five bucks, the wholesale cost is probably half that, and the cost to produce half again. Why not sell those to the developing countries? At least regular glasses won't fog up with algae in a short time. It's a clever idea making water-filled glasses, but how practical is it really?
