question 51

Multiple Choice

Myopia can be corrected with artificial lenses or surgery and is generally regarded as a benign disorder. However, as myopia is also associated with more severe conditions such as cataracts and glaucoma, a change in the prevalence of myopia (proportion of the population with myopia) may be a public health concern. The graph shows the change in the prevalence of myopia in three major ethnic groups in Singapore at three points in time.
