Behaviors that disrupt daily body clocks linked to nearsightedness in children and teens

Circadian rhythm-disrupting behaviors are closely linked to the onset and progression of myopia in children and adolescents.

• The prevalence of myopia in children and adolescents is rising globally.
• Irregular sleep schedules and increased nighttime exposure to artificial light may contribute to circadian rhythm disruptions.
• Circadian disruptions can manifest as sleep disorders, social jetlag, and excessive nighttime blue light exposure.
• Existing evidence suggests a potential connection between these circadian behaviors and myopia, although the mechanisms are not fully understood.
• The review summarizes current intervention strategies aimed at correcting circadian behavioral abnormalities to address myopia.
