Abstract
Protective and sports eyeglasses having a pair of integrally formed, wraparound lenses. The lenses have toric inner and outer surfaces which match each other on both meridians so that the lenses have zero power. A shock-absorbing nosepiece includes a base portion which wraps around a bridge integrally formed with the lenses and a pair of resilient, relatively large nose pads projecting downwardly and rearwardly along respective inside edges of the lenses. The nose pads are spaced slightly from the lenses so that they are capable of absorbing shocks imparted to the lenses. A pair of temples are pivotally secured to respective lenses by hinges which are embedded in respective mounting pads integrally formed in the lenses. The lenses may be formed from a tough, shock-resistant plastic, such as polycarbonate, and they may be provided with a hard, non-scratch coating.
