An Introduction to the Optics Manufacturing Process

Before the lens undergoes further grinding, the lens must be blocked, or mounted, to begin the process. Blocking involves mounting lenses onto a convex or concave surface (inverse of the tool being used) with pitch or wax. A lens can be blocked individually (Figure 3a), but more often, many lenses with the same radii are mounted on one surface

Digital Lens Basics: What You Need to Know

THE LENSES When lenses are tilted and turned, their optical power changes. The lens designer must cause the digital lathe to generate curvatures that yield the prescription shown by the test lenses, although the eyewear lenses are tilted and turned. In other words, the lenses "as worn" must give the power "as the patient tested."
