The aim of this study was to compare the relative peripheral refraction (RPR) at four different levels of illuminance, ranging from photopic conditions to complete darkness, using an open‐field autorefraction method. The RPR was calculated for each eccentricity by subtracting central from peripheral autorefraction measurements. The study included 114 myopic eyes from 114 subjects (mean age of 21.81 ± 1.91 years) and the mean difference in RPR between scotopic and photopic conditions (0 and 300 lux, respectively) was +0.32 D at 30° temporal and +0.37 D at 30° in the nasal visual field (NVF). Statistically significant differences were observed between 0 and 300 lux at 30° in the temporal visual field and at 30° and 20° in the NVF. Our results revealed a significant increase in relative peripheral hyperopia with increasing visual field eccentricity along the horizontal visual field in myopic eyes of young adults. Furthermore, this relative peripheral hyperopia increased as illumination decreased. These findings suggest that an increase in peripheral illuminance may protect against myopic eye growth. info:eu-repo/grantAgreement/ES/DGA-FEDER/E44-20R info:eu-repo/grantAgreement/ES/DGA-FSE/T24-20R info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 2.8 2023 OPHTHALMOLOGY 24 / 95 = 0.253 2023 Q2 T1 1.162 2023 Ophthalmology 2023 Q1 Sensory Systems 2023 Q1 Optometry 2023 Q1 5.1 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Remón, Laura Universidad de Zaragoza (orcid)0000-0002-3979-4528 Ávila, Francisco J.
