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. Even poor people are able to afford a pair of onedollarglasses.
The tough and rust-free spring steel wire is dermatologically proven skin compatible. It is first bent at the bending machine into rectangular sections.
Frames can be produced in different sizes: The yellow mark is for children's glasses, the red for medium sizes and the blue especially for people with bigger interpupillary distances.
