Parts for rimless eyewear frames: 

In one pair of rimless eyeglass frames, you will see three main parts, they are lenses, bridges and temples. For bridges and temples, there're screw on type and mounting on type,two types. For screw-on types of bridges and temples, they are mainly installed by screws,nuts etc, while for push on type of bridges and temples, the mounting sleeve is mainly used for installing them onto lenses. 

Except them,some small parts are easily to be ignored, but they are completely important for installing. For screw-on bridges, after putting bridges onto lenses, we need use washers, metal nuts and plastic caps inside of lenses for installing. Mounting on bridges are more convenient, only plastic mounting sleeve is necessary.
