The prevalence of myopia is rising, and, in some parts of the world, this rise can only be described as dramatic.1 For example, in many East Asian countries, the prevalence of myopia reaches 70% or more. Further, in the United States, the prevalence of myopia has doubled during the past 30 years, and the prevalence of high myopia (greater than -8.00 D) has risen eightfold. In China, the prevalence of myopia in young adults is greater than 75%.
