An eyeglasses lens machining apparatus works to perform a check operation implementation step of causing the apparatus to implement a check operation for checking a malfunction state of an operation of the apparatus, a self-restoration step of updating a calibration state of the apparatus related to the malfunction state, to self-restore the apparatus from the malfunction state, and a determination step of determining whether to shift to the self-restoration step, based on a result of the check operation. The apparatus works to further perform a measures output step of outputting information related to measures against an operation failure of a component in the apparatus, in which, in the determination step, it is determined whether to shift to the measures output step or shift to the self-restoration step, based on the result of the check operation.

Examples are directed to an approach to specifying design guidelines for fabricating a free-form optical component, and methods of fabricating the free-form optical components. In one example, a family of optical prescriptions is created, and a fabricator may manufacture the free-form optical element to any selected prescription within the family. According to certain examples, the series of prescriptions in the family each describe a very similar optical surface providing the same or similar optical performance, and are layered relative to one another such that the thickness of the optical element at any point is slightly less for each subsequent surface defined by the next prescription in the series.

The disclosure relates to methods for compensating for crystal structures differential material removal rates in sub-aperture figuring. A computing machine receives an input related to a substrate crystal structure. The computing machine generates, based on the input, a surface map data capturing the substrate crystal structure. The computing machine generates, based on the surface map data structure, a figuring route data structure for a figuring tool to figure an optical surface on the crystal substrate. The computing machine controls, using the processing circuitry and based on the figuring route data structure, the figuring tool to figure the substrate crystal optical surface.

Disclosed is a semi-finished lens that includes a blank formed in a first material having a first hardness, the blank having an outline, a first face and a second face configured to be surfaced so as to constitute a first optical face of the ophthalmic lens, and a top layer formed in a second material having a second hardness greater than the first hardness, the top layer having an outline, a first face and a second face, the second face of the top layer being arranged on the first face of the blank. The outline of the top layer is equal to or included in the outline of the blank, and satisfies to a predetermined dimensional selection criterion involving the final outline of the ophthalmic lens.
