    摘要: There is provided a spectacle frame 1, having a least one corrective lens the characteristics of which do not vary over time and having telemetry means 5 which set off an alarm 9, 10 when the distance measured by the telemetry means is less than a predetermined preference distance. This reference distance can for example be set at between 20 and 50 cm depending on the spectacle wearer. A kit is also provided comprising a frame, telemetry means and an alarm. The spectacle frame can be prescribed for slowing down the evolution of acquired myopia in children who are starting to acquire myopia; here, the spectacle frame is provided with progressive multifocal lenses. The telemetry means and alarm incite the child to respect a sufficient working distance for close vision.

    摘要: A device and process for determining the dominant eye of a patient (10), wherein the device includes a target (120), a camera (110) for acquiring an image of the patient's face, and a mask (200) to be positioned in front of the patient's face. The mask includes; a closure face (210) suitable for hiding the target from the patient while enabling the camera to see the patient's face, and a viewing window (220) for the patient to view the target and which is located through the closure face in order to enable the patient to view the target with only one of his two eyes.

    摘要: An ophthalmic lens including: a prescription control point (P); an upper area having, relative to the point (P), and average-power continuous variation ΔPuiSup that is monotonous between the point (P) and the point (Psup) (maximum variation point in absolute value) where the signed value of the variation ΔPuiSupMax=Pui(Psup)−Pui(P) is between −0.1 and −0.4 dioptres; a lower area having, relative to the point (P), an average power continuous variation ΔPuinf that is monotonous between the point (P) and the point (Pinf) (maximum variation point in absolute value) where the signed value of the variation ΔPuiinfMax=Pui(Pinf)−Pui(P) is between +0.1 and +0.4 dioptres; the average power gradient being lower than 4.10−2×ΔPuitotal, where ΔPuitotal=|ΔPuisupMax|+ΔPuiInfMax. Such a lens advantageously takes the accommodative dynamics of the eye into account and increases the visual comfort of the wearer.

    摘要: The invention relates to a method for determining an ophthalmic lens for a person (i.sub.1, i.sub.2, i.sub.3) to wear said lens, comprising the following steps: i) determination of the size (T.sub.1, T.sub.2, T.sub.3) or height of the eyes (H.sub.1, H.sub.2, H.sub.3) of the person to wear the lens; and ii) calculation of at least one characteristic of the ophthalmic lens according to the size (T.sub.1, T.sub.2, T.sub.3) or the height of the eyes (H.sub.1, H.sub.2, H.sub.3) of the person to wear the lens. The ophthalmic lens can be progressive strength or unifocal. The invention also relates to an optimization method and a method for producing an ophthalmic lens implementing such a definition method. The invention further relates to a set of lenses having at least one characteristic that depends on the size and the height of the eyes of the person to wear the lens.

    摘要: A progressive lens for ophthalmic spectacles has an additional zone for intermediate vision. This additional zone is located beneath a near-vision zone. It enables objects located at a distance of between 1.0 and 1.5 meters, in a direction inclined at about 35 degrees to a line of sight passing through a cross mark (CM) on the lens, to be seen clearly. To achieve this, the optical power progression between a far-vision point (FV) and a near-vision point (NV) of said lens has a power-increase threshold which is located approximately at the cross mark.
