ABSTRACT:
Rimless spectacles have the lenses which are not held by screws. The nose-bridge and the end-pieces of the temples consist of hook-like clamps that hold and touch the lenses for a short length from the front and/or the back side. These clamps together with a tight-thread or band going all the way around the lenses hold the lenses to the nose-bridge and end-pieces.
