The purpose of this study was to examine the sleep quality in high myopic children and adults.
This was a cross sectional study with 486 participants aged from 10 to 59 years with refractive errors.
A questionnaire containing the Pittsburgh Sleep Quality Index (PSQI) and Hospital Anxiety and Depression Scale (HADS) was used to generate findings.
Children aged 20 years or less in the high myopia group displayed the poorest PSQI scores (P < 0.01), while the adults showed no such correlations.
Subscales of PSQI and HADS in children showed that the high myopia groups had the shortest sleep duration (P < 0.01), worst subjective sleep scores (P < 0.001), and latest bedtime (P < 0.05).
Regression analyses in children correlated myopic errors with PSQI (P < 0.05), sleep duration (P < 0.01), and bedtime (P < 0.01).
Sleep efficacy (P < 0.05) and daytime dysfunction (P < 0.05) were significantly better in contact-lens users compared to the respective non-user groups in all participants.
The sleep quality in children was highly correlated with myopic error, and with the high myopia group worst affected.
