Over 700 million people worldwide need a pair of glasses but can't afford them. These people - many of whom live on a dollar a day or less - don't have the money to spare. The estimated loss of income caused by this fact is valued at about $200 billion per year. Adults cannot work to provide the basic needs of their families and students are unable to learn at school due to their weak eyesight. The solution? OneDollarGlasses. The materials needed to make a pair cost less than $1 and the glasses themselves consist of a lightweight, flexible spring steel frame with prefab lenses which and can be manufactured anywhere using a simple bending machine. To bring affordable glasses to communities OneDollarGlasses depend on donations. New bending machines have to be bought, components for glasses must be pre-financed and on-site training organised to develop a sustainable social enterprise.
