  • Spectacle frame having reverse nose pad
    Patent number: 5784143
    Abstract: An improved nose pad and spectacle frame. The spectacle frame includes a pair of temple pieces, a brow bar connecting the temple pieces, eye encircling rims depending from the brow bar, and reversely mounted nose pads which extend toward the tip of the user's nose, rather than the eyes. Optionally, a second pair of conventionally mounted nose pads may be provided. The reversely mounted nose pads improve weight distribution to minimize chafing, soreness and fatigue.
