User-Adjustable Glasses

DrLudicrous writes "An Oxford University professor has come up with a way to manufacture adjustable glasses. The lens is made up of silicone oil, which when added or removed changes the curvature, and thus the strength of the lens. Apparently, these are inexpensive enough to distribute to the poor people's of rural Ghana, who do not have the opportunity to see a doctor, let alone afford conventional glasses."
