There are two types of nose supports, one is fixed type, that is, non-metallic adhesive type; One type is stipule active type. The latter type of nose support is applied to the metal frame, and now it is also available on some high-grade plate glasses. The movable support is fixed by welding the support stem. We will only introduce the latter type of nose support as an example. This type of nose support is the most commonly used type, which is more comfortable than the previous one

It includes stipule stem, stipule box and stipule. The stipule is in direct contact with the nose and plays the role of supporting and stabilizing the mirror frame. Some cast plastic frames can have no stipule stem and stipule box, and the stipule is connected with the mirror ring.

The connection between the mirror ring and the mirror foot is generally curved.
