ABSTRACT:
Adjustable size protective eyewear in the form of visitor safety spectacles have a moveable or adjustable hinge pin coupling between the temple sidebars and the lens frame. An opening in each side of the lens frame contains multiple hinge pin sockets which are aligned at an angle with respect to the lens frame such that movement of the hinge pins from socket to socket not only increases the distance between temple sidebars but also the effective length from the lens frame to the ear piece of the temple sidebar. This arrangement allows a single pair of adjustable safety spectacles to be used by a person of a given head size with the adjustability to fit over the user's prescription eyewear where the user requires the prescription eyewear in addition to the safety spectacles.
