Definitions

  • an ophthalmic lens formed of a water-containing material it is possible to apply coloring to an ophthalmic lens in a dry state, but it is possible to add an appropriate ratio.
  • An ophthalmic lens in a state of being swelled by being hydrated, preferably in a state of being substantially completely swollen, is used. It is desirable to color the glass. This avoids discoloration that may occur due to swelling as compared to when the ophthalmic lens in a dry state is colored, and also reduces the coloring area when the ophthalmic lens in the swollen state is used. Advantages such as dimensional accuracy and sharpness of the outer edge can be advantageously secured.

  • the overlapping surfaces 12 and 16 of the ophthalmic lens 10 and the dye plate 14 may have a small gap of 1.0 mm or less, but the color elements scattered from the dye plate 14 may be present.
  • a predetermined laser light source 18 transmits the ophthalmic lens 10 through the ophthalmic lens 10 and irradiates the dye plate 14 with laser light 20 so that the dye is dyed from the dye plate 14.

Abstract

L'invention porte sur un nouveau procédé de coloration par faisceau laser qui peut être utilisé pour colorer une lentille de contact profilée ou une lentille intraoculaire, p.ex. pour inscrire des caractères ou des symboles, pour colorer une région spécifiée, ou analogue. Selon l'invention, on superpose une plaque de colorant (14) réalisée dans un matériau contenant un colorant à un côté d'une lentille oculaire (10), p.ex. une lentille de contact. Dans cet état, on irradie la plaque de colorant (14) avec un faisceau laser (20) afin de transférer le colorant de la plaque de colorant (14) à la lentille oculaire (10), colorant de la sorte la lentille oculaire (10).
