    Abstract: PROBLEM TO BE SOLVED: To provide a progressive multi-focal ophthalmologic lens where the relation between progression of the spherical aberration of eyeballs due to aging and a refraction abnormality is taken into consideration. SOLUTION: In this multi-focal ophthalmologic lens 11, the visual profile (unit: diopter) of the lens as a function of height (k) (unit: mm) on an axis A of the lens and the addition (Add) corresponding to the degree of presbyopia of a user is defined by P(h)=f(PVL, Add, h) +C(Add, PVL)h2 +B(Add,PVL) where PVL, (f), C(Add, PVL), and B(Add, PVL) are the vision (unit: diopter) required for far sight, a function of evolution between near vision and far vision, a spherical aberration correction coefficient determined by the addition and the far vision, and a vision correction coefficient determined by the spherical aberration coefficient. respectively.

    Abstract: This invention pertains to a process for the manufacture of a hydrophilic polymeric product, consisting in causing a material comprising a crosslinked silicone polymer matrix and photoinitiator groups dispersed and immobilized within the polymer matrix to swell in a swelling solution comprising a solvent for swelling the crosslinked silicone polymer of the matrix of the material, a photopolymerizable hydrophilic monomer and optionally a crosslinking agent and a proton- or electron-donating coinitiator compound, when the material comprises photoactivable photoinitiator groups and does not comprise proton- or electron-donating coinitiator groups causing the photopolymerizable hydrophilic monomer to diffuse into the swollen material, and polymerizing, by irradiation, the photopolymerizable hydrophilic monomer.

    Abstract: The contact lens (10) has one or more projections (12) on its outer surface (11) to interact with the wearer's eyelids. Each projection is elongated and curved in shape, following the line of the perimeter of the lens, and has sloping ends and a flat top. The angle covered by the flat top of a projection is equivalent to half the angle covered by the whole projection. The thickness of each projection is between 0.2 and 0.24 mm, and the radius of the arc of its centre line (L) is between 0.7 and 0.9 of the radius of the lens, and it covers an angle of between 60 degrees and 150 degrees .

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 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. … …

    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.
