Abstract
Background Dry eye disease (DED) is a disease of the ocular surface charac-terized by instability of the tear film, which causes ocular surface inflamma-tion and damage that leads to ocular symptoms, discomfort, and visual disturbance. Dry eye is a common ocular condition and a major reason for ophthalmologist visits. Compulsory e-learning has arisen in colleges and schools with the coronavirus disease 19 (COVID-19) pandemic as a tool for new teaching and learning. DED is an emerging threat to public health and is directly proportional to digital screen viewing length. DED diagnosis flowchart begins with history-taking of associated risk factors and a screening test by Ocular Surface Disease Index (OSDI). Therefore, we aim to assess the prevalence and the severity of DED among Jazan University lecturers and to identify the associated risk factors. Methods A total of 150 participants were recruited for this descriptive, observational study. Participants completed an online questionnaire that contained questions about sociodemographics, electronic devices they used, the average number of hours of use in a day as well as the distance and posture while reading, and factors that may influence visual symptoms such as the use of glasses, frequent changes in glasses prescription and DED symptoms. Results The results showed that the prevalence of DED was high, with 23% of participants having mild DED, 12% having moderate DED, and 29% having severe DED. DED was associated with a number of sociodemographic and clinical factors, including younger age, female gender, occupation as a lecturer, and use of digital devices. Conclusion This study highlights the need to develop strategies to prevent and control DED among high-risk groups, such as university lecturers. Future research should focus on identifying more effective ways to prevent DED and to improve the management of DED symptoms.
