ABSTRACT:
An intermediate lens pad having a side secured to curved surface of a lens tool when the pad is in use. The pad has a surface on its other side which is substantially smooth, but which is formed with a multiplicity of substantially uniformly distributed holes or recesses which are at least of an order of magnitude smaller than the pad itself, or the surface is defined by the outer surfaces of a multiplicity of protuberances uniformly distributed over the pad such that the minimum space between adjacent protuberances is of an order of magnitude smaller than the pad itself. A lens surfacing pad having a peel-off adhesive on one side and a working surface on its other side, can be secured by its adhesive side to the intermediate pad so that it inhibits movement between the pads during surfacing, whilst allowing manual removal of the surfacing pad for replacement.
