s7064 54-port 17-142 spectacle frame coding. What does this mean? Who can tell me. Then TR8019 53 port

1. s7064 54 ports 17-142: The frame model is 7064. The length of a single rim of the frame is 54MM, the length of the nose bridge is 17mm, and the length of the temples is 142mm

2. What do you think? The 8 means model 8019 according to what you wrote. The rim length of 53 is 1mm smaller than the previous 54MM you wrote. But you didn’t write down the length of the bridge of the nose and the length of the temples, so I can’t answer your question later
