Purpose: The aim of this study was to explore whether prolonged and consistent face mask use might be associated with worsening of dry eye symptoms in patients with dry eye disease (DED). Methods: Subjects with a previous diagnosis of DED. Their OSDI scores were compared with those recorded in Fall 2019 using the Wilcoxon paired test. Participants were stratified by face mask use: heavy (Group A) or standard (Group B) face mask users. Heavy use was defined as wearing any type of face mask for at least 6 hours a day, at least 5 days per week in the last 2 months. Results: 67 subjects (mean age: 45.27 ± 10.06 SD years, 40% males and 60% females). Median OSDI score in Fall 2019: 18.75. Median OSDI in Spring 2020: 20.83. The Hodges-Lehmann median difference was 2.09 (95% CI [1.05, 4.17]) (P < 0.0001). The population was then stratified into heavy and standard face mask users: Group A included heavy users (31 subjects; mean age: 42.81 ± 10.48 SD years; 35% males and 65% females), Group B included standard users (36 subjects; mean age: 47.39 ± 9.31 SD years; 44% males and 56% females). The Hodges-Lehmann median difference was 5.21 (95% CI [3.13, 7.29]) in Group A (P < 0.0001), and 1.04 (95% [0],[ 2.08]) in Group B (P = 0.0177). Conclusion: Prolonged and consistent face mask use is associated with an increase in OSDI scores. Whether face mask use is responsible for the worsening of symptoms of DED remains to be elucidated.
