Purpose : This study aimed to compare the face width and pupillary distance between Korean and Chinese adults and to compare the frame size and design shape of the currently worn spectacle frame.
Methods : Data were collected in a prospective manner for 100 adult men and women in their 20s and 30s, and 100 adult men and women in their 20s and 30s, respectively, who visited the Optometry office in Jilin Province China, Gyeongsan Korea. The face width was measured using a mobile application and PD meter was used to for far and near PD. The frame size was measured according to the Boxing system, and the frames design was e classified into shapes (round, oval, rectangle), rim shapes (full rim, half rim, no rim) and materials (plastic, metal, and combinations). For the analysis, one-way ANOVA for comparison among groups, Chi-Square analysis for frequency, Z-test for ration difference.
Results : Range of face width was 149.73±6.28 (Chinese woman) ~ 152.29±14.71 <단위 앞mm (Korean male), but there was no statistical significance between groups (p=0.147). There was statistical significance between groups in both far and near PD (p<0.001). There were statistical significance between groups for all of frame measurement (eye size, bridge size, vertical height) (p<0.001). There was statistical significance in all frame design except for the combination material (p=0.790).
Conclusion : This study showed that there was no face width difference between Korean and Chinese adult, but there was a difference in PD measurement. Frame size from Korean and Chinese wearers were clearly different showing that more Korean worn round shape of frame while rectangle shape was preferred by Chinese. Therefore when Chinese customer visit optometric practice in Korea, practitioner should be able to understand the different preference of frame design. When designing frame for overseas market, it will be necessary to consider face shape and local preference.
