Participants The participants in this study were 100 students from the Medical Faculty of Jenderal Soedirman University. Complete randomized design was adopted to receive proportional to size (PPS) sampling. Inclusion criteria were: no hand anatomical congenital deformities and anomaly, no destructive hand trauma history, no joints disease history, body mass index (BMI) 18,5-23 kg/m2, 19-21 years of age, in both the myopia and emmetropia group. Astigmatism, no responses, and no better correc- tion (NBC) or no correction (NC) refraction status were set as exclusion criteria. Data sources and settings Digit length was measured by a computer-based method. Participants’ right and left hand were scanned using Canon® CanoScan LiDE 120 (Vietnam). The measure- ment value was counted using a measurement tool on Adobe® Photoshop® CS6 in pixel(s) unit. Measurement was taken in Computer Laboratory in the Faculty of Medicine Jendral Soedirman University. An independent refractionist conducted refraction tests using a standard trial lens, trial frame and also automatic Snellen chart projector. Myopia degree was stated in spherical negative (S-) diopters and presented in numerical value. The test was done in the Public Eye Center (Balai Kesehatan Mata Masyarakat) Purwokerto. In order to avoid measurement bias, digit length measurement was executed by two observers.
