Association between dry eye and myopia in schoolchildren: current evidence and possible mechanisms

1

Myopia prevalence among schoolchildren has significantly increased, particularly in East Asia, affecting over 150 million children in China alone.
2

Dry eye disease (DED) is a major public health concern that negatively impacts learning, quality of life, and social functioning in schoolchildren.
3

Studies indicate that myopic individuals, including schoolchildren, have a higher prevalence of DED compared to their non-myopic peers.
4

The association between myopia and DED is supported by various mechanisms, including structural changes from axial elongation and behavioral factors.
5

High myopia is a pronounced risk factor for DED, with prevalence rates in myopic adolescents being 1.5 to 2 times higher than in non-myopic individuals.
