How the RB3691V fits

At 48mm to 50mm lens width, the Ray-Ban RB3691V sits on the narrow side of regular sizing. These will fit best on small to medium faces. The 21mm bridge is wide for this lens size, which positions the lenses farther apart and works well for those with wider-set eyes or broader nose bridges.

The phantos shape provides moderate vertical lens height, offering adequate space for single-vision prescriptions. Progressive wearers should verify the height meets their prescription requirements, as the rounded lower edge may limit the reading zone depending on the specific progressive design.

The full-rim phantos frame complements oval and heart-shaped faces by adding width at the browline. Angular faces including square and rectangular shapes may find the rounded curves soften their features, though the effect is less pronounced than with fully circular frames. Round faces typically need more angular frames to provide contrast.
