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]
