Abstract: Generally, glasses design in China is based on Caucasian head-face shape, as China is short of head-face data for glasses design. As a result, Chinese people usually find it is hard to buy a pair of suitable glasses. In this research, in order to discover the proper way of glasses design, the difference of Guangdong young man head-face shape with Kemar which is a average western head shape is compared based on the result of interviews from 136 glasses’ wearers. Through the study, it is found there are three parameters that influence the glasses design: how the difference of contour line of leg affect the design of leg form; how the contour line of ear impacted the ear piece’s design; how difference of face shape influence the design of nose pad and the pupillary distance influence the frame width. At last, we put forward the correct way for glasses design which would be used as an reference for the design of glasses.

Key words: head shape, 3D data of head shape, shape parameter, glasses design
