Abstract: A safety unit combining eye and hearing protection in which retention of earcups on the head of wearer is by resilience of separate side arms carrying the earcups. The resilience is resisted by a provision of a rigid frame to spectacles, or a rigid beam to goggles. Snap fitting of arms to the frame or beam enables use of the arms with either spectacles or goggles. The spectacle lens or goggle visor is separate from the rigid frame or beam.

Abstract: A safety spectacle which allows for easy fitting and removal of lens parts to cater for individual requirements, including provision of single or twin lenses comprises a frame which is apertured to receive a lens or lenses of the spectacle and having abutment means over at least part of said aperturing which present retention faces to inside and outside surfaces of said lens or lenses, and clip means releasably locatably engageable with the frame and cooperable with the lens or lenses to retain the same in the spectacle frame in conjunction with the operation of the abutment means.
