Abstract
Abstract Safety glasses for use, in particular, in sporting activities comprise a frame to which two limbs are articulated, two lenses mounted on the inside of grooved retaining circles formed in the frame and a nose rest piece which fits together with the frame, is made of flexible material and has walls which form a part of the said grooved retaining circles. In such glasses therefore the lenses are partly held by flexible material which avoids their being broken in the case of a heavy blow as may for example occur when playing a sport. The risks therefore of cuts or injuries to the wearer of the glasses are reduced.
