Abstract
A lens holder for an apparatus for grinding the edges of a lens. The lens holder includes two coaxial, rotatable shaft halves having adjacent ends between which the lens is held. One of the shaft halves is axially shiftable to permit insertion, securing, and removal of the lens. To secure the lens, the axially adjustable shaft half is connected with the piston of a piston/cylinder unit or with a portion of a worm or screw drive. To release the lens, the piston of the piston/cylinder unit, or the gear portion of the worm or screw drive, is manually axially moved along with the shaft half.
