Abstract
An adhesive blocking system, for generating and for fining and polishing eyeglass lenses, utilizes a collar which slides over and engages a lens block, which lens block is secured to a lens blank by a relatively thick adhesive pad, to uniformly transfer pressure from the cylinder machine to the lens blank without deforming the adhesive pad, which deformation adversely affects the optics. In this manner, a lens blank is blocked only once for both generating and fining and polishing. In addition, the environmental risks and heating effects of current solder blocking systems are avoided.
