A lens block having a compliant structure adapted to receive and hold a lens blank or similar optical element is disclosed. The flexibility of the block, itself, ensures that the optical element can be held without breakage during the various shaping operations, such as grinding, edging, and polishing, encountered in preparing a lens for mounting in an eyeglass frame or similar receptacle. The block can be a disposable element coated with, or otherwise carrying, an adhesive material for simple application to lens blank. In one embodiment, a compliant lens block is formed having a dish-shaped receiving surface on one side for receiving the lens blank and an appropriate key structure on the other side for mounting into the chuck of a grinding lathe, edger or other lens shaping machine. The lens-receiving surface is divided into two or more flexible lands, separated at least partially by slots, so that the shape of the dish is compliant and, therefore, can conform to the lens blank, regardless of curvature or surface discontinuities.
