摘要: A lens holder assembly (49) and method of using the lens holder assembly (49) to mark an ophthalmic lens (3) is provided. The lens holder assembly (49) comprises a stem (61) having a central axis and a first opening (5) extending along the central axis of the body (65), a second opening (7) integrated within the stem (61) such that the second opening (7) is substantially parallel to the first opening (5), and at least one illumination source positioned within the second opening (7). The illumination source is capable of emitting light through the second opening (7) for illuminating at least a portion of an ophthalmic lens (3). At least a portion of the lens (3) is placed over the first opening (5). Suction is applied to the lens (3), and a marking is applied to a surface of the lens (3).

摘要: Systems and methods for providing identification factors for an individual wearer. Some or all of the identification factors when within a predetermined value provide a prescription and corrective ophthalmic lenses for a selected individual wearer, the corrective ophthalmic lens having at least one correction that is to the nearest 0.20 diopter, or is in a range between about the nearest 0.01 diopter and about the nearest 0.20 diopter. The prescription and corrective ophthalmic lenses are obtained by at least first analysis performed with a first instrument, a second analysis performed with a second instrument, and a third analysis performed with a third instrument, in which each instrument is different, and each analysis is different.

摘要: A pair of progressive ophthalmic lenses (1, 2) meets special conditions for improving binocular vision of a wearer, while avoiding discomfort for peripheral vision. A first one of the conditions relates to height values of far vision fields, intermediate vision fields and/or proximate vision fields, for indicating that the fields are different enough in height between both lenses. A second one of the conditions sets a maximum value for the relative difference in mean refractive power gradient between both lenses.

摘要: An instrument has a light-emitting and light-receiving assembly including an image capture unit and image processing unit; a backscatterer and an opening provided therein; a support for receiving an ophthalmic lens between the assembly and backscatterer, the assembly, support and backscatterer placed so that an incident light beam traverses the lens, strikes the backscatterer, returns and re-traverses the lens to arrive at the capture unit; the light-receiving assembly, the support, backscatterer and opening configured so that the assembly receives light from the beam; and the opening and a drive device for cyclically driving and making the backscatterer perform an identical movement in each cycle, configured so that a fixed zone opposite the backscatterer includes at least one part of which, over the course of a cycle, every point is at times perpendicular to the opening and at times perpendicular to a solid portion part of the backscatterer.

摘要: The present invention relates to a group of novel electrochromic materials. More specifically, it relates to electrochromic materials based on either single or two-core viologen systems and the use of these viologen systems as a variable transmittance medium for the manufacture of an optical article, such as an ophthalmic lens.

摘要: Progressive multifocal ophthalmic lens having a power addition (Add) and an astigmatism prescription, and having a far vision point CM, a near vision point NV, and an intermediate vision point IV positioned between CM and NV. The resulting astigmatism in the far and near vision zones is smaller than or equal to the resulting astigmatism in the intermediate vision zone, wherein the resulting astigmatism is the difference between the prescribed astigmatism and the astigmatism generated by the working lens under usual wear conditions. The lens provides good optical quality images in the far and near vision zones, and the resulting astigmatism in the intermediate vision zone encourages the wearer to use the far and near vision zones rather than the intermediate vision zone, thus reducing the risk of increasing the degree of myopia of the wearer in the long term.
