Abstract: The method involves measuring the deviation produced by a lens (L) to light rays, and determining the value of refraction characteristics of the lens at a measurement point. The lens is maintained fixed with respect to a lighting unit. The position of measurement axis is variable from one measurement from to anther measurement for adapting to that of the measurement point of the lens. An independent claim is also included for an apparatus for measuring refraction characteristics of a lens in a specific point.

Abstract: L'invention concerne un procédé de détourage d'une lentille (L1) ophtalmique comprenant les étapes de blocage initial de la lentille en un point de blocage initial (Pb1) déduit selon une règle de calcul du contour voulu (C1) de la lentille, détourage de la lentille, déblocage de la lentille, et de reblocage de la lentille en un point de reblocage (Pb2) en vue de sa reprise.Pour la détermination de la position du point de reblocage, on acquiert le contour (C2) de la lentille tel qu'obtenu après le premier détourage et on en déduit la position du point de reblocage.

Abstract: The method involves displaying a shadow of centering reference of an ophthalmic lens and a virtual target of centering relative to a reference point of a ring of a spectacle frame. A corrected position of the point relative to the reference is deduced from prismatic deviation of an opaque sign measured by comparing shadow of the sign and shadow deviated by the lens. The reference shadow is manually coincided with the target. An independent claim is also included for a centering-blocking device.

Abstract: The device has a transparent support plate (121) for receiving an ophthalmic lens (103). A light source (S) for the lens is installed on the plate, and an acquisition and analysis unit for the light transmitted by the lens. A transparent support (124) is provided for an opaque sign that is activated and deactivated and is arranged between the plate and the acquisition and analysis unit. An independent claim is also included for a method of manual centering of an ophthalmic lens.

Abstract: The device has a support (110) to receive an ophthalmic lens and movable in translation along two axes perpendicular. The support has a passive pointer (113) that forms a reference image on light acquisition and analysis units, when lighted by a lighting unit (120). An active pointer emits a signal received by the light acquisition and analysis units. The units acquire and analyze the light sent by the lens.

Abstract: The device has a pattern filter (140) placed between a lighting unit (120) and a support that is adapted to receive an ophthalmic lens (10). The filter permits the device to exert progressive addition lens identification function. Two polarizing filters arranged between the lighting unit and the support allows the device to exert tensiscope function. A power measurement unit enables the device to exert frontofocometer function. The device permits to automatically verify centering characteristics of the ophthalmic lens in progressive addition lens identification mode, to automatically locate stress existing in the lens in tensiscope mode, and to measure or verify power in a reference point of the lens or mark and measure the power of single vision lens in frontofocometer mode.
