Abstract: Disclosed are systems and processes for generating a finished or semi-finished lens, such as a spectacle lens, from a lens blank that includes an intermediate functional layer. Some embodiments of the process involve locating the functional layer and positioning the lens blank according to the location of the functional layer. The location of the functional layer can be ascertained by measuring the thickness of one or more layers of the lens blank. The lens blank can be surfaced on one or both sides to form a finished or semi-finished lens. Other embodiments are also described.

Abstract: Disclosed are injection molds, injected molded articles, and methods for using the same. The injected molds include a mold cavity and an injection molding conduit having a first end, a second end defining an outlet in fluid communication with the mold cavity, a first interior transverse dimension that is perpendicular to a longitudinal axis of the injection molding conduit, a second interior transverse dimension that is perpendicular to the longitudinal axis and to the first interior transverse dimension, and at the second end, the second interior transverse dimension is at least three times larger than the first interior transverse dimension, and the second interior transverse dimension of the injection molding conduit is substantially aligned with a thickness of a portion of the mold cavity that is adjacent to the outlet of the injection molding conduit.
