  • Patent number: 8506858
    Abstract: 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: introducing a starting material into a lens mold (3) comprising a male mold half (30) and a female mold half (31) defining a mold cavity between the shaping surfaces of the male and female mold halves, the shaping surfaces being arranged at a first rotational position relative to one another and at least one of them being toric, and curing the starting material in the mold cavity to form the first toric lens.

  • Patent number: 7726237
    Abstract: 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 cliché with an ink. When in use the pad transfers an inked image from the cliché 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.

  • Patent number: 7255438
    Abstract: A method comprises the steps of (a) providing a water based ink in at least one cliché with a contact lens pattern; (b) transferring the water based ink from the cliché to at least a surface of at least a contact lens forming mold by means of at least a transfer pad; (c) at least partially curing the ink transferred on the mold to form a colored film; (d) dispensing a hydrogel lens-forming material into a lens-forming cavity of the mold; and (e) curing the lens-forming material within the lens-forming cavity to form the contact lens, whereby the colored film detaches from the molding surface and becomes integral with the body of the contact lens; characterized in that the relative air humidity in the immediate vicinities of the transfer pad/s is kept higher than 50% at standard temperature and pressure conditions during ink transfer.

  • Publication number: 20060077341
    Abstract: The invention provides a method for producing colored contact lenses with high quality color images. The method of the invention comprises the steps of (a) providing a water based ink in at least one cliche wherein a pattern to be printed on the contact lens has been created; (b) transferring the water based ink from the cliché to at least a surface of at least a contact lens forming mold by means of at least a transfer pad; (c) at least partially curing the ink transferred on the mold to form a colored film; (d) dispensing a hydrogel lens-forming material into a lens-forming cavity of the mold; and (e) curing the lens-forming material within the lens-forming cavity to form the contact lens, whereby the colored film detaches from the molding surface and becomes integral with the body of the contact lens; characterized in that the relative air humidity in the immediate vicinities of the transfer pad/s is kept higher than 50% at standard temperature and pressure conditions during ink transfer.
