Purpose: To determine the prevalence of refractive errors among Saudi adults in Riyadh, Saudi Arabia. Methods: A cross-sectional study was conducted targeting healthy Saudi adults (20–40 years old) at two major gatherings in Riyadh, Saudi Arabia from December 2018 to January 2019. Refractive errors were measured, and data pertaining to age, sex, region of origin, and spectacle use was collected. Clinically significant myopia was defined as SE ≥ -0.50 D, hyperopia as SE ≥ 0.50D, and astigmatism as cylindrical error ≥ 0.50D. Refractive error measurements were assessed using Topcon's Auto-Kerato-Refractometer, KR-800. Results: A total of 660 adult individuals (1,319 eyes) were included in this study, of which 321 participants (48.7%) were found to be myopes, 167 subjects (25.2%) were hyperopes, and 438 individuals (66.3%) had astigmatism. With regards to correlations, myopia was highly correlated with being male (P-value = 0.036), belonging to age group 20–25 years (P-value = 0.033), originating from the northern regions of Saudi Arabia (P-value <0.001). Similarly, hyperopia was significantly correlated with being male (P-value = 0.048), age groups 20–25 years (P-value = 0.04), and 31–35 years (P-value = 0.011) and was higher in people from northern region (P-value = 0.011). In contrast, astigmatism was only found to be correlated with age group 36–40 years (P-value = 0.002). Additionally, 71.7% of myopic participants and 76.1% of astigmatic individuals opted not to wear spectacles (P-value <0.001). Conclusion: In this study, the refractive error with the highest prevalence among Saudis was astigmatism, followed by myopia and hyperopia. Gender, region of origin, and spectacle wear were all observed to be highly correlated with higher rates of refractive error.
