Barriers to health care access present critical challenges to improving eye health that are dynamic and complex, yet few studies have been able to quantitatively measure the impact of these barriers. This study aims to determine the association between initial barriers to seeking care and time since last eye exam (TLEE) utilizing a mobile screening clinic that provides comprehensive eye exams in Oregon. Participants (N=1699) from screenings conducted between 2014 and 2016 completed a demographic and subjective visual acuity questionnaire, and received a comprehensive dilated eye exam. Data regarding demographic information, subjective visual acuity, and measured visual acuity were analyzed with respect to TLEE and compared to the American Academy of Ophthalmology recommendations for preventive eye health exams.
