Abstract: A lens holder assembly (49) and method of using the lens holder assembly (49) to mark an ophthalmic lens (3) is provided. The lens holder assembly (49) comprises a stem (61) having a central axis and a first opening (5) extending along the central axis of the body (65), a second opening (7) integrated within the stem (61) such that the second opening (7) is substantially parallel to the first opening (5), and at least one illumination source positioned within the second opening (7). The illumination source is capable of emitting light through the second opening (7) for illuminating at least a portion of an ophthalmic lens (3). At least a portion of the lens (3) is placed over the first opening (5). Suction is applied to the lens (3), and a marking is applied to a surface of the lens (3).

Abstract: A self-service kiosk for dispensing eyewear is disclosed. The kiosk includes a display for depicting available frame and lens options to customers. A user interface accepts eyewear order information from a customer including the customer's prescription information and frame selection. The kiosk also includes a lens manufacturing device that is wholly contained within the kiosk for manufacturing optical lenses in the prescription of the customer, which are adapted for the selected frame. Further, the kiosk includes a dispensing mechanism for dispensing from the kiosk the manufactured lenses, along with the customer selected frame.

Abstract: A method of fast curing polythiourethane transparent casted substrate, usable for making optical articles such as ophthalmic lenses, which comprises the steps of: 1) Providing a first component A comprising a polythiourethane prepolymer having isocyanate or isothiocyanate end groups and a viscosity at 25° C. ranging from 0.02 to 0.4 Pa.s; 2) Providing a second component B comprising a polythiourethane prepolymer having thiol (SH) end groups and a viscosity at 25° C. ranging from 0.2 to 2.0 Pa.s; 3) Mixing together first and second components A and B and filling a moulding cavity of a casting mould assembly with the resulting mixture; 4) Curing said mixture to obtain a transparent solid substrate, said curing step comprising: a) a first step for polymerizing said mixture to obtain a gel within 1 to 10 minutes; and b) a second step of post-curing the gel to obtain the transparent solid substrate; and 5) Recovering the transparent solid substrate from the mould.
