A process for the automatic manufacturing of different toric optical lenses having a front surface and a rear surface having a predetermined rotational orientation relative to one another, and with at least one of the front and rear surfaces having a toric portion, comprises forming a first toric lens by: The process further comprises subsequently forming a second toric lens different from the first toric contact lens using the same male and female mold halves () by

Process and apparatus for the automatic manufacturing of different toric optical lenses

A drying nozzle () for drying a peripheral portion of an ophthalmic lens (CL), in particular a contact lens, comprises an inlet () for the supply of a pressurized gas and a continuous annular outlet gap () having a predetermined width (W) through which the pressurized air is capable of being supplied to the peripheral portion of the ophthalmic lens (CL).

Drying nozzle

A printing station for producing a layer of coloring for a contact lens, comprising a transport system to carry and transport a molding tool which comprises at least one contact lens forming mold, a pad unit comprising at least one pad, and a blade unit suitable to carry and ink a clich&#xe9; with an ink. When in use the pad transfers an inked image from the clich&#xe9; to the contact lens forming mold. The printing station further at least partially cures the inked image after it has been transferred to the mold and cleans the pad.
