KEY HIGHLIGHTS:

  • Myopia is the leading cause of preventable blindness in children and young adults.

  • Multiple epidemiological studies have confirmed a high prevalence of myopia in Asian countries. However, fewer longitudinal studies have been performed to evaluate the secular changes in the prevalence of myopia, especially high myopia in China.

  • The present study investigates trends in the prevalence of myopia among high school students in Fenghua city, eastern China, from 2001 to 2015.

  • From 2001 to 2015, the prevalence of overall myopia increased from 79.5% to 87.7% while the prevalence of low myopia decreased from 32.7% to 24.4%.

  • High myopia and very high myopia contributed the major part of the increasing trend of myopia prevalence (contribution rate 27.00% and 69.07%, respectively).

  • During the 15-year period, there was a remarkable increase in the prevalence of high and very high myopia among high school students, which might become a serious public health problem in China for the next few decades.
