Abstract: Refractive errors (REs) remain a leading cause of visual impairment worldwide. Understanding their prevalence and associated risk factors is essential for early intervention, particularly in populations with high academic demands such as medical students. Medical students frequently report a high burden of REs, possibly attributable to genetic influences and lifestyle factors like extended near-work activities and limited outdoor exposure. Limited data exist on the prevalence and determinants of REs among medical students in the United Arab Emirates. This study aimed to determine the prevalence of REs in this population and elucidate the key potential risk factors associated. A cross-sectional survey was conducted among medical students at the United Arab Emirates University. A validated 14-item questionnaire assessed the presence and type of REs, demographic and physical characteristics, educational level, family history, electronic device usage, and sunlight exposure. The survey was disseminated electronically between November 2023 and February 2024.
