Which mounting type connects the lenses primarily at the bridge?

The correct answer is that a semi-rimless mounting primarily connects the lenses at the bridge. In this type of mounting, the lower half of the lenses is typically left unframed, while the upper part is held securely by a frame or attachment at the bridge. This design allows for a lighter aesthetic and can provide a more open feel compared to full-rim or rimless mountings, where the lenses may be encased entirely or held only by a minimal connection.

Semi-rimless mountings are particularly popular because they combine style with functionality, showcasing a modern appearance while still providing necessary support for the lenses. The bridge connection is essential in ensuring the lenses remain stable and properly aligned on the wearer's face.

Rimless mountings do not have a frame surrounding the lenses, relying instead on a lighter structure that typically connects the lenses at the temples and possibly at the bridge, but without the support a semi-rimless frame provides. Full-rim mountings encase the lenses completely, offering a different support and aesthetic approach, while Numont mountings, which are known for their minimalist style often featuring only a bridge and temples with no bottom rim, are less common in everyday optical offerings.
