Beschreibung
Zusammenfassung:	A lens for eye, such as a contact lens or an intraocular implant, of novel structure that while ensuring excellent optical properties, has a lens configuration of satisfactorily small thickness and can realize a variety of lens power. This lens has such a characteristic structure that at least one pair of diffraction gratings (24,24) are provided in the internal part of the lens for eye (10). L'invention concerne une lentille pour l'oeil, telle qu'une lentille de contact ou un implant intraoculaire, d'une structure nouvelle. Tandis que cette structure garantit d'excellentes propriétés optiques, elle présente une configuration de lentille de petite épaisseur satisfaisante, et elle permet de réaliser diverses puissances de lentille. Cette lentille possède une telle structure caractéristique qu'au moins une paire de grilles de diffraction (24, 24) se situe dans la partie interne de la lentille pour l'oeil (10).
