Abstract
It is estimated that over 285 million people are visually impaired globally, with 39 million of them completely blind. A person with low vision is considered to have a best corrected vision of 20/70 or worse in their better eye. In the U.S., a visual acuity of 20/40 is necessary to be able to drive without restriction. Eighty percent of people that have low vision are in low-income settings and 82% are over 50 years of age. As life expectancy continues to increase, the number of people that will have some degree of vision impairment is expected to continue to rise.
