More than 950 million of people world wide are suffering from defective vision. They could be helped by a pair of simple eyeglasses. These people - many of them living on one Dollar a day or less - don't have the money to buy eyeglasses.
These people cannot work and many young people are not able to go to school due to uncorrected eyesight. The estimated loss of income caused by this fact is valued near 269 billion USD per year.
