The OneDollarGlasses consist of an extremely lightweight, flexible and stable spring steel frame and prefabricated lenses which are made of polycarbonate. The entire material and manufacturing cost of the glasses will come to approximately 1 USD. The OneDollarGlasses are produced by the local people on a specially designed bending machine. This bending machine is the core of the concept of OneDollarGlasses. It requires no electrical power and is virtually maintenance-free, so it works in every however remote African village. During a 14-day intensive training men and women are trained to work as OneDollarGlasses optician, so that they can start their own business.
