摘要:
A gripper for grasping an ophthalmic lens immersed in a liquid, for example a contact lens or soft contact lens, the gripper including a housing having an opening arranged at the distal end of the housing, the opening being in communication with an interior space defined by the housing and being sized to allow the ophthalmic lens to pass therethrough; a supply channel to generate suction in the interior space of the housing to allow the ophthalmic lens together with an amount of the liquid in which the ophthalmic lens is immersed to be sucked through the opening into the interior space of the housing; and a supply channel for generating overpressure in the interior space of the housing so as to allow the ophthalmic lens together with the amount of liquid to be released from the interior space through the opening at the distal end of the housing.
摘要:
The present invention relates to a mold half for making an ophthalmic lens, in particular a contact lens, wherein the mold half comprises a release sheet removably arranged on the mold surface of said mold half to separate a lens forming material from the mold surface, as well as to a method for applying a removable mold release sheet to said mold half. The mold half of the invention comprises a vacuum means to removably attach said release sheet to said mold surface, and preferably the mold half further comprises a pinch-off rim for forming the edge of said ophthalmic lens.
摘要:
There is described a method for the simultaneous manufacture of contact lenses having different lens parameters on the same production line, where a number of molds, each comprising male and female mold halves, are transported in sequential rows of and in each row in side by side configuration through a series of treatment stations, which are arranged sequentially along a production line, in which lenses of specific parameters are manufactured from a lens forming material. During manufacture each lens is associated with a lens identification code. There is also described a closed cycle production line for carrying out the method.
