Abstract: The lens has a power profile related to the height (h) above its axis (A) and the addition (Add) corresponding to the degree of the wearer's presbyopia is defined by the formula: P(h) = f (PVL, ADD, h) + C (ADD, PVL) h + B (ADD, PVL) where PVL is the power required for distance vision, f is a function of the evolution between the powers for close and distance vision, and B (Add, PVL) is a power correction coefficient dependent on the coefficient of spherical abberation.

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 .

Abstract: Artificial multifocal ocular lens has transparency which decreases with increases brightness. Lens has at least two corrective zones, as in fig. 1, a near zone = ZVP, and a far zone = ZVL and it is particularly adapted for correcting long sight.

Abstract: Les deux lentilles (2H, 3P) du jeu sont du type à vision simultanée progressive, avec l'une (2H) des lentilles dont le profil progressif varie d e sorte que la puissance est plus importante au centre qu'en périphérie alors que po ur l'autre lentille (3P) c'est l'inverse. La gamme comporte deux séries de lentilles dont la puissance nominale s'échelonne suivant un pas prédéterminé, par exemple de 0,25 dioptries. Le procédé comporte un examen optométrique standard, la détermination de l'oeil offrant la meilleure tolérance à une défocalisation myopique, et pour chaque oeil la sélection d'une lentille dans une série respective de la gamm e, en fonction des résultats de cet examen.

Abstract: Il s'agit d'une lentille oculaire artificielle comportant annulairement au moins deux zones concentriques, à savoir une zone de vision de près (ZVP) plus particulièrement adaptée à une correction de la vision de près et une zone de vision de loin (ZVL) plus particulièrement adaptée à la correction de la vision de loin. Suivant l'invention, la transparence de cette lentille oculaire artificielle multifocale varie suivant une fonction décroissante de l'éclairement dont elle est l'objet, un composé photochromique ayant en pratique été incorporé à cet effet à son matériau constitutif, ce qui permet d'améliorer ses performances optiques. Application, notamment, aux lentilles de contact à vison de près centrale.
