The prevalence rate among medical students is an important issue to consider. This study investigates the relationship between caffeine consumption, sleeping habits, use of electronic devices, and DED among a convenient sample of medical students in Jordan.Methods: This cross-sectional online survey enrolled medical students from all six medical schools in Jordan. The questionnaire, which was shared via social media platforms, assessed socio-demographics, caffeine consumption amounts and patterns, sleep quality, and the use of electronic devices and their relation to ocular discomfort, DED, and related symptoms. The ocular surface disease index (OSDI) questionnaire was also administered to quantify the symptoms of DED.Results: A total of 1223 students participated in this study (RR=24.46%); 64% were females, and 43% were in their clinical placement years. Of the participants, 317 (25.92%) had normal eyes, and 906 (74.08%) had symptomatic DED. Of the students, 1206 (98.6%) used electronic devices directly before bed, and only 399 (32.62%) used blue-light-protective glasses. Lower DED risk was linked to male gender (OR=0.535, 95% CI 0.392– 0.73, p < 0.01), clinical years of medical school (OR=0.564, 95% CI 0.424– 0.75, p< 0.01). Poor sleep quality corresponded to more incidence of DED, regardless of sleeping for 5– 6 hours (OR=3.046, 95% CI 1.299– 7.139, p=0.01) or for less than 5 hours (OR=3.942, 95% CI 1.824– 8.519, p< 0.01). Also, caffeine consumption only marginally affected its incidence, but the results were statistically insignificant.Conclusion: Female gender, basic science years, and spending more than 6 hours looking at screens were significantly associated with symptomatic DED. Caffeine consumption did not pose any significant risk to the incidence of DED.Keywords: caffeine, dry eye, medical students, screen exposure, sleep quality
