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.
