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.

Myopia is caused by an elongation of the eyeball, resulting in a longer-than-normal axial length. Therefore, an increase in the prevalence of myopia would be accompanied by a greater proportion of the population with longer-than-normal eyeballs.
