Abstract: Disclosed is an adjustable nose pad structure comprising a traverse having two legs at its opposite ends sized and shaped so as to be applied at least partially to the nose, and fixing structure for fixing the traverse to the rear side of the bridge of the eyeglasses. The fixing structure comprises a series of passage-communicating hollow divisions made in the free end length of each leg and two male projections integrally connected to the bridge or rim in the vicinity of each bridge-to-rim transition. These male projections can be inserted in the passage-communicating hollow divisions, so that the traverse may be fixed to the bridge or either rim of the eyeglasses at a controlled distance from the front of the eyeglasses to fit the eyeglasses to a face.
