Nearsightedness, or myopia, affects more than 40 percent of people in the U.S. and up to 90 percent of children in some parts of Asia. The problem begins in childhood and often progresses with age. Standard prescription lenses can correct the defocus but do not cure nearsightedness, and do not slow progression rates as children grow. But recent experimental work by biomedical scientist David Troilo and colleagues at the State University of New York (SUNY) College of Optometry in New York City supports the development of a potential cure for myopia by using specialty contact lenses that coax the eye to grow in a way that can correct nearsighted vision while reducing myopia progression.
