Date Nov. 15, 1990.The present invention relates to a method of manufacture of an optical lens providing refractive index modulation, characterized in that, starting from a lens of transparent hydrophilic polymer preferably of the hydrogel type, which has previously been shaped, the lens is impregnated with a photopolymerizable composition containing at least one monomer and a photoinitiator, which are in solution in water in the case of a hydrogel, the impregnated lens is subjected to locally modulated irradiation so as to cause local selective polymerization of the monomer, whereupon the excess non-hardened photoinitiator and non-pulverizable monomer is removed.

Abstract: The present invention relates to an ophthalmic lens which characteristically comprises at least two concentric regions (110, 120) possessing diffractive components (110a, 110b...; 120a, 120b...) having differing phase profiles in order to utilise differing diffraction orders (n). The diffractive components (110a, 110b...; 120a, 120b...) can be formed from 3-D holograms or index holograms.

Abstract: Un composant optique transparent à structure cellulaire comprend un réseau de parois (106) qui forme un ensemble de cellules (104) juxtaposées parallèlement à une surface du composant. Pour réaliser un tel composant, on détermine d'abord un ensemble irrégulier de points (101, 105) dans la surface du composant, chaque point étant destiné à former un centre d'une des cellules. Ensuite, on détermine une position et une orientation de chaque paroi, de sorte que l'ensemble des cellules forme une partition de Voronoï de la surface du composant. Le composant présente alors un niveau de transparence qui est compatible avec une utilisation optique ou ophtalmique.

Abstract: The lens comprises diffracting components, the contour of which is delimited by non-degenerate centred conic sections. More precisely, according to the invention, the lens comprises adjacent diffracting components of hyperbolic or elliptical contour whose periodicity in r in two mutually-orthogonal directions X, Y, passing through the axis of the lens and being coincident with the principal axes of the hyperbolae or ellipses is determined respectively by the expressions: DELTA r x = 2 lambda ¦fx¦ , DELTA r y = 2 lambda ¦fy¦ in which: DELTA r x represents the periodicity in r in the direction X, DELTA r y represents the periodicity in r in the direction Y, lambda represents the average wavelength of use, fx represents the desired focal point in the plane X and fy represents the desired focal point in the plane Y. … …
