The Cobra safety glasses prescription is a wrap-around pair of positively sealed safety glasses.  They have a sunglass style, a curved frame front to fit into the face’s contour to aid eye protection and comfort. It has flexible temple ends that go over the ears like most sunglasses to hold these prescription safety glasses close to the head.

This is the black frame as pictured.

They are also positively sealed and non-conductive.  This frame comes with a detachable adjustable elastic strap, so you know they will stay where they’re meant to be.
