A lens care container (), in particular for contact lenses such as hard or soft contact lenses, comprises: The sensor () is arranged in the receptacle () when the cap () is attached to the receptacle ().

Lens care container

A cleaner for cleaning grippers for the transport of ophthalmic lenses comprises:

Cleaner for cleaning grippers for ophthalmic lenses

A production line (PL) for the production of ophthalmic lenses () comprises The manufacturing module (MM) comprises a plurality of manufacturing stations (). At least one of these manufacturing stations () is configured to apply a lens identification code () to the respective lens. The lens identification code () includes information indicative of the type of the respective lens. Either the inspection module (IM) or the packaging module (PP) includes a lens detection station () configured to read the lens identification code () applied to the respective lens and to detect the type of the lens from the lens identification code () read from the respective lens in order to determine whether the type of lens detected actually is the type of lens which is expected to be detected by the lens detection station () at that time.

Modular production line for the production of ophthalmic lenses

A lens inspection module comprises: Cleaning shuttle comprises a driving unit a cleaning head, a suction unit, and a tube connecting cleaning head and suction unit. Cleaning head is spaced apart from suction unit and driving unit in the transportation direction and is pivotally arranged about a pivot axis. Cleaning head may comprise a distance sensor for detecting the distance between cleaning shuttle and transportation shuttle. Driving unit is configured to change the speed of the self-driving cleaning shuttle when the distance between the cleaning shuttle and the transportation shuttle is shorter than a predetermined threshold distance.

Lens inspection module

A manufacturing module (MM) for contact lenses comprises a plurality of manufacturing stations () arranged in a closed loop and a plurality of lens mold carriers () which are transported through the manufacturing stations. Each lens mold carrier () comprises a frame () having a predetermined number of mounting sites () arranged along the frame. Each lens mold carrier () further comprises a predetermined number of molds () removably mounted to the frame () at the mounting sites (), the molds being reusable male or female molds (). Two lens mold carriers () are assigned to each other to form a pair, so that upon mating the pair of lens mold carriers () the male and female molds () are mated to form mold cavities defining the shape of the lenses. The manufacturing stations comprise a mold changing station () configured to be capable of removing a mold from its mounting site () and mounting a different mold at the said mounting site (), or configured to change the rotational position of a mold () mounted to the frame (), or both.

A modular production line for the production of contact lenses comprises at least three separate modules: The modular production line further comprises fixedly arranged transfer interfaces between the individual modules (MM, IM, PP) for transferring the lenses from a preceding module to a subsequent module. The manufacturing module (MM) comprises a plurality of manufacturing stations () which are grouped to form a plurality of individual manufacturing units () arranged in a closed loop. Reusable male and female molds () are transported through the manufacturing stations of the manufacturing units, and each manufacturing unit () comprises a plurality of the manufacturing stations (). A plurality of transfer robots () is provided, each transfer robot () of the plurality of transfer robots () being arranged at a location between two manufacturing units () to transfer the reusable molds from one manufacturing unit to the other manufacturing unit.

A casting mold () for the manufacture of ophthalmic lenses, in particular hard and soft contact lenses comprises a male mold half () having a generally convexly shaped male mold surface () and a female mold half having a generally concavely shaped female mold surface (). Each of the male and female mold surfaces comprises a lens-forming surface () which is encircled by a non lens-forming annular edge surface (). The lens-forming surface () comprises a central optical zone () and a non-optical peripheral zone () surrounding the central optical zone. At least one of the male and female mold halves () is provided with at least one permanent marking () which is arranged on a surface in the peripheral zone () of the lens-forming surface () and/or on the non lens-forming annular edge surface ().
