Abstract: A contact lens with a central portion, an iris portion, and a peripheral portion disposed about the iris portion; wherein the iris portion contains an arcuate colored or tinted portion that provides a shadow effect; the peripheral portion can be colored white and can have a pattern that graduates to transparent towards the outer diameter of the lens.

Abstract: Methods for slowing progression of myopia or hyperopia of human patients include a step of providing contact lenses. The contact lenses have two or more refractive powers. A first refractive power provides clear visual acuity and a second refractive power provides a defocused retinal image to the human patient. The methods involve providing first and second sets of the contact lenses, the contact lenses of the second set have a different optical design than the contact lenses of the first set. With the present methods, an eye care practitioner is able to select one or more contact lenses from the second set of contact lenses based on one or more ocular parameters of the patient, one or more responses of the patient to the contact lens of the first set, or both, to provide an improved clinical benefit to the patient compared to the benefit provided by the first set of contact lenses.

Abstract: A transparent optical component (10) comprises at least one transparent set of cells (15) juxtaposed parallel to a surface of the component, each cell being separated by walls (18) parallel to the component surface, hermetically sealed and containing at least one substance having an optical property, and at least one absorbing coating (30), placed on the walls on one side extending parallel to said component surface. The optical component can be cut out along a predefined contour and optionally drilled. The invention also comprises a method for producing such optical component and its use for producing an optical element. The optical element may be a spectacle lens in particular.

Abstract: A bifocal or multi-focal contact lens (5) having a geometrical lens center point (4) comprises a near-circular near vision zone (10) having a first geometrical center point and a near-circular far vision zone (8) having a second geometrical center point. The near vision zone (10) and the far vision zone (8) are concentrically arranged, whereby the first geometrical center point and the second geometrical center point coincide and form a common correction center (6) and said correction center (6) is located at a distance from the lens center point (4). Said contact lens (5) ensures optimized visual acuity without intermediate zones, in particular in the case of presbyopia. Furthermore, said contact lens can be produced in a simple and low-cost manner.

Abstract: A gradient tinted shield may include one or more areas of gradient opacity, varying vertically from a user's eyeline. In one implementation, two areas of gradient opacity are located on the gradient tinted shield, one above the user's eyeline and one below the user's eyeline. Further, an area of constant opacity may be located at the user's eyeline.

Abstract: Ophthalmic lenses provide clear visual acuity and present a myopic defocused image to the lens wearer at both near and distant viewing distances. The present lenses are used in methods to reduce ocular accommodative error in lens wearers. Methods of manufacturing the present lenses are described.

Abstract: A design method of a spectacle lens, includes: measuring an angle formed by a direction of a head of a person seeing the front without lens and a direction of the head of the person seeing an object located in a direction angled to the front direction of the person without lens to calculate a visual action index Mn according to the following equation (1) as an initial value; temporarily designing a spectacle lens based on the visual action index; and simulating visual action of the person wearing the temporarily designed spectacle lens and correcting the visual action index based on the simulation result M n = ? n ? n ( 1 ) wherein ?n is an angle formed by the front direction of the person and a direction in which the object actually exists, ?n is a rotation angle of the head of the person seeing the object without lens, and n represents the object.

Abstract: A method for generating a trimming setpoint for an ophthalmic lens for it to be fitted in a surround of a half-rim spectacle frame, includes the steps of: a) acquiring the planar coordinates of a plurality of first points characterizing the shape of a first longitudinal profile of the surround; b) determining the spatial coordinates of second points of a second longitudinal profile, obtained from a projection of the first longitudinal profile onto a predetermined reference surface, c) calculating the perimeter length of the second longitudinal profile, d) determining the spatial coordinates of third points of a third longitudinal profile, obtained from a projection of the first or of the second longitudinal profile on a curved surface deduced from a shape parameter of the ophthalmic lens, e) correcting the spatial coordinates of the third points, so as to equalize the perimeter length of the third longitudinal profile with the perimeter length of the second longitudinal profile, f) deducing the machining s
