The optician can easily hold spectacle lenses with these spectacle forceps.
The jaws consist of two round plates, which are covered with rubber on the
inside. This way, the glasses are not damaged and you have a better grip on
them. One jaw is mounted on a spring, so that the pressure is applied more
gently to the glass. This jaw can also move slightly up or down. The other
jaw is slightly larger and hollow on the inside for the convex side of the
glass. A spring opens the pliers automatically. [MOT]
