Purpose : To provide data that can be used to measure the progressive corridor and related parameters for prescribing progressive addition lenses, using the photographing measurement and smart centering device measurement. Methods : The pupillary distance, optical center height, vertex distance, pantoscopic tilt and frame wrap angle were measured using the photographing measurement. The amount of downward eye movement for the progressive corridor was calculated based on the near working posture, along with the measured parameters. The values obtained from photographing measurement were compared with smart centering device measurement. Results : The study was conducted on 25 adult with visual acuity better than light perception at both far and near distances. The amount of downward eye movement calculated using the photographing measurement was 10.12±3.33 mm on average, and it was found to increase as the near working distance decreased(r=-0.418, p<0.050). A comparison of the parameter measurements between the photographing and the smart centering device showed no significant differences in the pupillary distance at both far and near working distances and frame wrap angle(p>0.050). However, significant differences were found in optical center height, vertex distance, and pantoscopic tilt, which are more influenced by vertical head movement(p<0.050). The amount of downward eye movement measured with the smart centering device was 9.67± 1.99 mm, which was 0.46±3.35 mm shorter than the value obtained with the photographing measurement, although no significant difference was found(p>0.050). Conclusion : This study analyzed near working posture and downward eye movement, and compared the photographing measurement with the smart centering device measurement to provide basic data for prescribing progressive addition lenses.
