Summary
University students with high myopia showed significantly worse subjective happiness, higher anxiety/depression scores, and a tendency toward eveningness chronotype with delayed sleep timing compared to students with mild or no myopia. These findings suggest that optimal optical correction and myopia prevention in childhood may have downstream benefits for circadian health and mental wellbeing in adolescents.
Key Findings
- High myopia group had significantly worse Subjective Happiness Scale (SHS) and Hospital Anxiety and Depression Scale (HADS) scores compared to mild myopia and no myopia groups (p < 0.05)
- Regression analysis showed myopic error correlated with poor SHS (p = 0.003), eveningness chronotype (p = 0.032), later wake-up time (p = 0.024), and later bedtime (p = 0.019)
- Pittsburgh Sleep Quality Index (PSQI) scores were not significantly different among the three myopia groups
- Sample comprised 153 university students: high myopia (n=44), mild myopia (n=86), no myopia (n=23)
Categories
Sleep & Circadian Health: High myopia was significantly associated with eveningness chronotype, later bedtimes, and later wake times in university students.
Mood & Mental Wellness: High myopia correlated with significantly worse subjective happiness and higher anxiety/depression scores compared to mild or no myopia groups.
Eye Health & Vision: The study examines myopia as a factor influencing sleep chronotype and mental health outcomes in young adults.
