Methods: Twenty-four healthy subjects with a mean age of 22.9±2.3 years (18-33) participated in this study. An iPad and an e-ink reader were chosen to present calibrated text, and each task lasted 5 minutes evaluating both ambient illuminance level and luminance of the screens. Results:Eye-tracker data revealed a higher number of saccadic eye movements under minimum luminance than under maximum luminance. The results showed statistically significant differences between the iPad (p=0.016) and the e-ink reader (p=0.002). The length of saccades was also higher for the minimum luminance level for both devices: 6.2±2.8 mm and 8.2±4.2 mm (e-ink max vs min), 6.8±2.9 mm and 7.6±3.6 mm (iPad max vs min), and blinking rate increased significantly for lower lighting conditions. Conclusions: Performing reading tasks on electronic devices is highly influenced by both the configuration of the screens and the ambient lighting, meanwhile, low differences in visual quality that are transient in healthy young people, were found. info:eu-repo/grantAgreement/ES/DGA/LMP39_21 info:eu-repo/grantAgreement/EC/H2020/956720/EU/Opto-Biomechanical Eye Research Network/OBERON This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 956720-OBERON info:eu-repo/grantAgreement/ES/MICINN/PID2019-107058RB-I00 info:eu-repo/grantAgreement/ES/UZ/JIUZ-2021-CIE-03 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 1.3 2023 OPHTHALMOLOGY 64 / 95 = 0.674 2023 Q3 T3 0.521 2023 Ophthalmology 2023 Q2 Sensory Systems 2023 Q3 2.9 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Safarian Baloujeh, Ebrahim Navarro, Rafael (orcid)0000-0002-1328-1716 Sanchez-Cano, Ana Universidad de Zaragoza (orcid)0000-0002-5621-1937 2002 647 Universidad de Zaragoza Dpto.
