Abstract:ObjectiveTo investigate repeatability of refractive state using a smartphone-based assessment tool, the Near Eye Tool for Refractive Assessment (NETRA).Methods and analysisThis study included 279 participants, predominantly female (66.7%) of African descent (49.1%). The age range was 9–63 years with mean age (s) 22.6 (8.9) years. Two consecutive measurements per eye with the NETRA were measured for both eyes of all participants.
