Visual impairment caused by uncorrected refractive error is an avoidable global health problem. The World Health Organization estimates that 153 million individuals worldwide have untreated refractive error, leading to reduced vision.1 Of this large population, 8 million are blind.1 Subnormal vision often leads to limitations involving educational development, employment opportunity, social acceptance, and overall quality of life. Recent pediatric reports in Australia, India, China, and the United States have found visually significant uncorrected refractive errors in 8% to 21% of children.2- 4 Early detection and treatment of refractive error in children is critical for preventing amblyopia, a disorder of the maturing visual system that can lead to permanent visual loss despite the use of glasses in adulthood.
