We tell you name of each part and how they work, and basic words of glasses.
| Frame front | The whole front part of a frame. |
|---|---|
| Temples | Thin and long parts that bridge end-pieces and ears. |
| Rim | The outer edge of frame front the holds lenses. There are some different designs of rim; the one that has only top or bottom half of the rim or rimless ones. |
| Hinges | A part that connects frame front and temples and it opens and closes temples. |
| Bridge | A part that is placed at the center of frame front and it connects both lenses. We call single bridge and double bridge based on the design. |
| Nose pads | A part that holds a frame and where contacts with nose. |
| Nose pad arms | Metal arms that connect rim and nose pads. The height and angles of nose pads can be fully adjusted with these two arms. |
| End-pieces | A side part that connects hinges and frame front. |

| Full-rim | A design that rim entirely holds lenses. |
|---|---|
| Half-rim | A design that rim holds only top/bottom half and a lens is fixed in right place with a nylon string. We call the one “half under rim” which has only bottom half rim. |
| Rimless | Bridge and end-pieces hold both lenses and it doesn’t have rim. It looks natural on face as it has no rim but needs careful handling attitude as nothing covers lenses. |

| Plastic Frame | A frame that the most of a frame front is made of plastic. Acetate is widely used recently as it has wide range of color choices. We also call “celluloid made frame” as a plastic frame. Celluloid has unique color and texture. |

| Combination Frame | A frame that frame front is made of plastic and metal. |
