    摘要： The invention relates to a device for determining the rotation center of the eye of a person with respect to a point of reference assigned thereto or to the part of the spectacles thereof. The inventive device makes it possible to determine the visual axis of said person in at least two non-parallel directions by means of a visualised target and to define an optimal point called a crossing point of said axes in the form of the eye's rotation center, wherein at least to positions with respect to said target (2) and the person's head are measured. According to the invention, said target consists of a light source and is placed at the end of a tubular support (3) whose other end is placeable in front of the person's eye and which carries a first position sensor (4), wherein a second position sensor (7) is placeable on the person's head.

    摘要： The invention relates to a method for checking the correct assembly of a device consisting of a frame and of two corrective ophthalmic lenses. The main feature of a method according to the invention is that it includes the following steps: an initial step of determining at least one parameter which makes it possible to position the lenses in the frame relative to the face; a subsequent step of acquiring at least one image of the face of said wearer with said device, which shows centring and horizontal level marks; a step of comparing said at least one parameter determined during said initial step with the corresponding parameter deduced from said at least one image; and a step of making a decision regarding the correct assembly of the device.

    摘要： An ophthalmic lens (10) comprises an optical component (1) and a layer (2) placed on a face of the optical component (1a). The layer (2) has a variable refractive index and is structured so that a second order derivative of the index with regard to a linear spatial coordinate along the face of the optical component (1a) is greater than a fixed threshold. The layer (2) makes it possible to alter the optical power and astigmatism of the lens (10) with regard to corresponding values only relative to the optical component (1). In the event that the ophthalmic lens (10) is a progressive lens, the layer (2) makes it possible to change an addition, a length of progression and/or a design of the progressive lens.
