ABSTRACT:
An inflated floating bridge piece is provided for use on eyeglass frames to increase comfort, reduce slippage and allow for height adjustment of the glasses. The bridge piece is in the form of a resilient, hollow member having one or more air chambers in an inverted U shape adapted to fit over the bridge of the nose in place of conventional eyeglass bridges. The inner wall of the bridge is thinner than the outer wall to provide control over bridge pressure and an adjustment plate bears against the cross piece to selectively adjust the pressure in the chamber or chambers.
