Abstract
Apparatus and method for edging an ophthalmic lens comprises a spindle on which a lens is removably positioned and set rotating to engage with a web of abrasive material which is secured at only one end thereof. The free end of the web is allowed to dangle and is also preferably set into an oscillating, vertical movement which edges both the anterior and posterior surfaces of the lens adjacent the lens periphery to thereby smooth the periphery of the lens.
