    摘要: The invention relates to a process for marking an optical eyeglass (1) equipped with a surface coating (5) comprising the following steps: A step of detreating by means of a laser beam, so as to locally detreat an area of the optical eyeglass by removing the surface coating (5) until a lower layer (7) of the eyeglass (1) is reached, which layer is located under said coating (5) and made of a material that is different from the surface coating (5), thus forming at least one the detreated zone (6, 11), A step of depositing an ink (9) in the detreated zone (6, 11) in order to form at least one inked pattern (4), so that the ink (9) adheres to the lower layer (7) present at the bottom (10) of the detreated zone (6, 11).

    摘要: Optimizing visual performance of a spectacle lens using metrics of visual performance includes selecting one or more metrics of visual performance for the lens. Creating functions of the metrics of visual performance, each having a function value that decreases as a values of the metrics of visual performance increase. Creating a merit function for lens optimization, the merit function having a main term that contains a weighted sum of functions that decrease as the metrics of visual performance increase, the weighted sum of functions including a set of viewing directions or a set of points with a one-to one correspondence with the set of viewing directions. Minimizing the merit function to optimize lens surfaces. Then designing an optimal lens having the optimized lens surfaces to optimize visual performance.

    摘要: A progressive spectacle lens, a method for its production, and a related computer program are disclosed. The progressive spectacle lens has a progressive surface including a central viewing zone, a lower viewing zone, two peripheral vision zones extending bilaterally from a vertical meridian of the progressive surface, and an upper viewing zone. The central viewing zone has a surface power providing a first refracting power for distance vision and the lower viewing zone has a greater surface power than the central viewing zone providing a second refracting power corresponding to near vision and being connected to the central viewing zone by a first progressing power region. The progressive spectacle lens generates a retarding or arresting effect on myopia progression, especially in myopic juveniles.

    摘要: An optical lens intended to be worn in front of an eye of a wearer having at least one prescribed refractive power Px. The optical lens includes a refraction area having a refractive power based on the prescribed refractive power Px for the eye of the wearer and including at least the central zone of the optical lens, and a plurality of optical elements having an optical function of not focusing an image on the retina of the eye of the wearer. The optical elements are arranged based at least on the prescribed refractive power Px and the shape of the retina of the wearer.

    摘要: An eyeglass managing system determines process parameters for manufacturing at least part of an eyeglass including a lens and a frame. In this eyeglass managing system, an electronic system includes: —a receiving unit adapted to acquire lens data describing an initial lens and frame data describing an initial frame; —a processing unit adapted to identify, based on the lens data and on the frame data, modification parameters deriving from the interaction between the initial lens and the initial frame; and—a transmitting unit adapted to transmit a list of proposed modifications based on the identified modification parameters. The receiving unit is further adapted to acquire a response to at least one proposed modification; the processing unit is further adapted to determine, based on the acquired response, process parameters of an additive manufacturing process for manufacturing the lens or the frame.
