| Abstract: |
An eyeglass support device is disclosed in which a pair of frictionally restraining clamps support lower peripheral regions of the eyeglasses while keeping the bridge of the eyeglasses substantially free from the wearer's nose to avoid pressure following surgery or injury. The substantial eyeglass weight depending from the wearer's ear-temple junctures is transmitted to the wearer's cheekbones, shifting the eyeglasses outwardly from the nose without materially affecting the optical axis. In one example, a cheek pad coupled T-bar stem threaded in the clamp portion adjusts the distance between the eyeglass periphery and the cheek surface; a cheek pad pivotably coupled to the stem is further adjustable to conform to the wearer's cheek. In another example, the device comprises a swivelable ball joint coupling the clamp to the cheek pad. In a further example, the eyeglasses are supported by T-shaped elements each comprising a crosspiece having a cheek contacting surface and an extending stem terminating in partially extensible retaining jaws for gripping the lower rim of a lens structure.

What is claimed is:
1. A visual aid which substantially avoids physical contact pressure on the nose of the wearer comprising:
- eyeglasses of the type having a pair of lenses in juxtaposition, each lens defining a lower peripheral region, a bridge interconnecting the lenses and a pair of arms each extending normal to and coupled to outermost portions of each lens, each arm extending rearward for being disposed and bearing on the juncture region connecting the ear and temple of a wearer, and being partially frictionally engaged thereby; and
- a pair of eyeglass support means joined to the lower peripheral region of each of the lenses for bearing on each cheek of the wearer, each eyeglass support means comprising an eyeglass engaging clamp, a cheek pad and means coupling the eyeglass engaging grip to the cheek pad, such that the substantial gravitational force of the eyeglass when frictionally pivoted about the temple juncture region is vectorially transmitted through the eyeglass engaging clamp to the cheek pads, the cheek pads frictionally engaging the cheeks and providing sufficient reaction force to maintain the eyeglass elevated above and forward of the nose of the wearer at approximately level vertical alignment with the field of vision of the wearer, thereby introducing minimal vertical imbalance in refractive error.
