The design consists of the following parts:
- The frame is the front part holding the lenses. Consists of rims in which lenses are inserted.
- The bridge holds the bezels of the frame. It may have nasal stops that help evenly distribute the weight of the product, or be naked.
- The earhooks hold the frame in position. Must be a suitable size and curvature. In optics stores, they are often bent for a specific person.

- Tips - soft lining on the earhooks made of silicone or plastic. They protect the skin from possible reactions to the metal.
