The World Health Organization estimates that 333 million people are blind or visually impaired. Nearly half of these, 154 million are suffering from uncorrected refractive error, with more than 13 million of them children.
Individuals so affected are handicapped in a variety of ways from being deprived of
educational opportunities to being limited in the workplace and even being burdens to their families. The economic impact both personally and in terms of society at large is huge.
