What bridge design rests on the sides of the nose without touching the crest?

The keyhole bridge design is specifically crafted to rest on the sides of the nose without making contact with the nasal crest. This design feature is crucial for individuals who may have a pronounced nasal bridge or for those who prefer a style that alleviates pressure from the center of the nose.

The keyhole bridge typically includes a "keyhole" shaped aperture that allows the frame to fit snugly on the sides while leaving the area over the crest clear. This not only enhances comfort but also contributes to better stability and fit of the eyewear.

Other bridge designs have different characteristics: the saddle bridge sits more fully on the nose and covers a larger area, potentially touching the crest, while the comfort bridge may distribute weight more evenly across the nose but does not have the same specific design intention as the keyhole for avoiding contact with the crest. The strap bridge design features a more traditional appearance with distinct support that is not necessarily designed to avoid the nasal crest area.
