Abstract: A method for superposing a first ophthalmic lens having a first face and a second ophthalmic lens having a second face in order to build an optical assembly delimited by the first and second faces. The method includes detecting respective positions in space and shapes of the first and second ophthalmic lenses, by using at least one sensor, detecting a first reference point on the first ophthalmic lens and a second reference point on the second ophthalmic lens, based on these respective positions in space and shapes, and modifying the respective positions so as to superpose the first and second reference points.

Abstract: A method of analyzing a visual field of an individual comprises the following steps: —measuring (S4) a first visual field (VF1) of said individual for a first set of oculo-postural parameters of said individual when said individual performs a first task; —measuring (S6) at least one additional visual field (VFi) of said individual for one additional set of said oculo-postural parameters of said individual when said individual performs an additional task; —determining (S8) a functional visual space based on said first visual field (VF1) and said at least one additional visual field (VFi), said functional visual space being an envelope of said first visual field and said at least one additional visual field. The additional task differs from said first task and/or said additional set of oculo-postural parameters differs from said first set of oculo-postural parameters. A corresponding ophthalmic lens is also proposed.

Abstract: A manufacturing system carries out a method for additively manufacturing ophthalmic devices, and includes a tank filled with a predetermined material, a single curing device for curing volumes of the predetermined material to harden layers of the ophthalmic devices, a layering device for layering volumes of the predetermined material onto harden layers of the ophthalmic devices. The manufacturing system includes building platforms movable relative to the tank and on which are supported the ophthalmic devices. The number of building platforms is determined by the predetermined material, curing time for the single curing device to cure a volume of the predetermined material, and a layering time for the layering device to provide a volume of the predetermined material to form a subsequent layer for hardening, so the layering device and the single curing device perform respectively curing and layering simultaneously on layers from different ophthalmic devices.

Abstract: A photography and thermography combining method of obtaining, for a chosen spectacle frame model of a spectacle wearer, at least one fitting parameter to fit an ophthalmic lens into the spectacle frame model. The method includes taking a photograph of the wearer's face with spectacles having the chosen spectacle frame model, taking a thermogram of the wearer's face with the spectacles, identifying the spectacles' contour in the thermogram, overlaying the identified contour or a boxing shape derived from the identified contour onto the photograph, thus obtaining a composite image, and obtaining the at least one fitting parameter from the composite image.
