Effect of MyopiaEd Messaging on Improving Eye-use Behavior and Myopia Control Among Primary School Students in China

Effect of MyopiaEd Messaging on Improving Eye-use Behavior and Myopia Control Among Primary School Students in China: A Randomized Controlled Trial

Myopia represents a significant global public health challenge, with China experiencing particularly high myopia prevalence among children and adolescents. The World Health Organization (WHO) acknowledges the critical role of health education in eye care and has collaborated with the International Telecommunication Union (ITU) to launch the Be He@lthy, Be Mobile (BHBM) initiative, which includes MyopiaEd-a mobile health project specifically designed to address myopia. Developed in partnership with international experts and informed by evidence-based guidelines, MyopiaEd provides standardized, scientifically validated content for effective myopia control. The MyopiaEd library has been translated and adapted by the Zhongshan Ophthalmic Center for use in China. Therefore, we aim to investigate whether the Chinese version of MyopiaEd can improve eye care behaviors among primary school students and enhance parental knowledge regarding myopia prevention and control in China.
