An eyewear frame having at least one frame component including a stimuli-responsive polymer is provided. The at least one frame component has a physical property which is reversibly changeable in response to a stimulus of non-thermal origin applied to the stimuli-responsive polymer. An eyewear including the eyewear frame, and a method of adjusting the eyewear frame are also provided.

Method means for optimizing an optical lens adapted to a wearer, using an initial optical system providing stage (S), during which an initial optical system is provided. The initial optical system has at least a light source (), a light receiver () and an initial optical lens (L) placed between the source () and the receiver (), the initial optical lens a Fresnel zone, a working optical lens defining stage (S), for evaluating a working optical lens is defined to be equal to the initial optical lens (L), an evaluation stage (S), during which a cost function related to the number of light rays received by the light receiver () that have passed through the annular step of the working optical lens, a modifying stage (S), for modifying the annular step of the working optical lens, wherein the evaluation and modifying steps are repeated to minimize the cost function.

A spectacle ophthalmic lens mountable on a spectacle frame, the ophthalmic lens including: a fitting cross where the optical power is negative; a first zone extending in a temporal side of the fitting cross, wherein in the first zone when the ophthalmic lens is mounted on the spectacle frame, the optical power increases when a gazing direction moves towards the temporal side, and wherein over a nasal side of the fitting cross, the optical power of the ophthalmic lens is substantially same as at the fitting cross.

Method for defining one face of an ophthalmic lens, having a surface formed by superposing a Fresnel layer and a continuous surface referred to as the 'carrier'. Also disclosed is an ophthalmic lens comprising such a face. The method allows a Fresnel layer to be defined that compensates for geometric effects induced by a variation in the curvature of the carrier on the light incident on the face of an ophthalmic lens. This method is particularly useful when the curvature of the face of the ophthalmic lens is adapted to facilitate fitting it into a spectacle frame.

Optical patches are assigned to prescriptions so as to reduce the total number of patch surfaces which are involved. The prescriptions are produced by varying at least one of a front patch surface (S) and rear patch surface (S) which are combined to form an optical patch, in accordance with prescription segments. The front patch surfaces (S) are pseudo-spherical and the rear patch surfaces (S) include a Fresnel structure superimposed on a pseudo-spherical base shape.

Method for determining front and rear surfaces for optical patches

A method for calculating or optimizing an ophthalmic lens design comprising the steps of providing a given ophthalmic lens design and assessing the given design by a computer comprising a media suitable for storing electronic instructions.

Method for assessing an optical feature of an ophthalmic lens design

A method of selecting a semi-finished ophthalmic lens according to a given spectacle frame comprising the steps of: providing the spectacle frame front face base data providing a list of semi-finished ophthalmic lenses with a plurality of front face bases, and selecting from the list of semi-finished ophthalmic lenses the semi-finished ophthalmic lens whose front base is the closest from the front base of the spectacle frame.

Method of selecting a semi-finished ophthalmic lens according to a given spectacle frame

A method for selecting base-curves for an ophthalmic lens according to given prescription data comprising the steps of: providing a base-curve series consisting of a plurality of base-curves; calculating a target lens according to the prescription data; calculating the base-curves calculated lenses according to the prescription data; selecting, for at least an optical parameter and/or a geometrical parameter, a threshold value for the difference between the base-curves calculated lenses values and the target lens value of said parameter(s); determining the list of the base-curves of the base-curve series where said difference for said parameter(s) is less or equal to the selected threshold value(s).
