Abstract
Abstract The invention provides a spectacle frame having on its inner (rear) face a circumferential channel, and frame-to-face seals carrying a mating ridge on the outer (forward) face of each seal. The spectacle frame is converted to an air-vented safety goggle, to a watertight swimmer's goggle or to an underwater diving mask by mating the appropriate frame-to-face seal with the channel in the frame; the frame can carry plano or prescription ground lenses and may be provided with temples or with an elastic headband.
