| dc.description.abstract | Background. Myopia is a refractive error in which light is focused in front of the
retina, resulting in blurred vision, particularly among young individuals. Increased
near-work activities such as reading and prolonged digital device use have
contributed to the rising prevalence of myopia. Previous studies suggest that visual
disturbances and circadian rhythm alterations associated with myopia may affect
sleep quality. Objective. To determine the association between moderate and high
myopia with sleep quality among young adults. Methods. This analytical cross
sectional study involved 40 medical students from the Faculty of Medicine,
Universitas Sumatera Utara, academic years 2022–2023, who were examined at
the Eye Clinic of Prof. dr. Chairuddin P. Lubis Universitas Sumatera Utara
Hospital, Universitas Sumatera Utara, Medan, 20155, INDONESIA. Myopia
severity was assessed using the Snellen chart, while sleep quality was measured
using the Pittsburgh Sleep Quality Index (PSQI). Data were analyzed using Fisher’s
Exact test. Results. Most respondents were 21 years old (60%) and male (57.5%).
Moderate myopia was found in 62.5% of participants, while 37.5% had high
myopia. Poor sleep quality was reported in 52.5% of participants with moderate
myopia and 35% of those with high myopia. Fisher’s Exact test yielded a p-value of
0.633 (p > 0.05), indicating no significant association between myopia severity and
sleep quality. Conclusion. There is no significant relationship between moderate or
high myopia and sleep quality among young adults.
