TitleThe Hidden Power of Sleep on Eye comfort
PurposeDry Eye Disease (DED) is a prevalent, multifactorial condition that impairs quality of life. While a link between sleep and DED is clinically suspected, it remains underexplored in Europe. This prospective study investigated the relationship between sleep and tear film quality and quantity.
MethodsWe investigated forty-two healthy participants aged 18-40. The sleep quality and quantity were assessed using the Pittsburgh Sleep Quality Index (PSQI) and self-reported sleep duration the night before the exam. The tear film was evaluated with the Schirmer test and the tear break-up time (TBUT). Dry eye symptoms (DES) were assessed via the Ocular Surface Disease Index (OSDI) and Dry Eye Questionnaire-5 (DEQ-5).
ResultsThirty-seven participants (mean age 25 years; 73% female) were analyzed. DES were present in 33% (OSDI), reduced tear production (Schirmer <5 mm) in 11% and short TBUT (<10s) in 89% of the participants. Poor sleep duration (<6 h) showed no significant correlation with DES or tear film parameters. Poor sleep quality (PSQI ≥5) was reported by 62% and was significantly associated with DES (43.5% vs. 14.3% in good sleepers, r = 0.591, p < 0.05), but not with TBUT or Schirmer scores.
ConclusionPoor sleep quality is linked to dry eye symptoms in a young European cohort, while objective tear measures showed no clear association. Findings highlight the importance of assessing sleep quality in dry eye management and suggest that improving sleep may benefit perceived ocular surface health.
