摘要:
The invention relates to a device for measuring the subjective refraction of a person in near and/or medium vision, which comprises, according to the invention, for each eye of the person, a correction mounting (3) provided with at least one corrective lens, the correction mountings (3) being arranged such that the person looks through the lenses. The position of each correction mounting (3) is variable such as to adjust an angle (a) between the axes of the lenses.
摘要:
A multifocal ophthalmic spectacle lens (10) capable of correcting a wearer's ophthalmic vision and having a back surface (BS) and a front surface (FS), said lens comprising a light guide optical element arranged to output a supplementary image (SI) to the wearer through an exit surface (ES) of said light guide optical element, where the exit surface (ES), the back surface (BS) and an optical material located between said exit surface (ES) and said back surface (BS) form an optical device (OD) and wherein said optical device (OD) comprises an area of stabilized optical power.

摘要:
A progressive ophthalmic spectacle lens (10) capable of correcting a wearer's ophthalmic vision and having a back surface (BS) and a front surface (FS), said lens comprising a light guide optical element arranged to output a supplementary image (SI) to the wearer through an exit surface (ES) of said light guide optical element, where the exit surface (ES), the back surface (BS) and an optical material located between said exit surface (ES) and said back surface (BS) form an optical device (OD) and wherein said optical device (OD) comprises an area of stabilized optical power.
摘要:
A method of calculating an optical system (OS) of an ophthalmic lens according to a given spectacle frame, said ophthalmic lens comprising a back surface (BS) and a front surface (FS) arranged to deliver an ophthalmic vision image (VI), a light-guide optical element having a proximal surface (PS) and a distal surface (DS), said light-guide optical element being arranged to output a supplementary image (SI), wherein the method comprises the steps of: providing at least a morpho-geometrical parameter data of the frame or of the light-guide optical element; optimizing the optical system (OS) according to at least the morpho-geometrical parameter data as a target.
摘要:
A quality control method for optometric measurements includes the following steps: (a) recording, via computer, a first record (14) that includes at least one first value of a first identifier (12), enabling identification of a glasses wearer (1), and at least one other value of another identifier (13) enabling identification of an optometric apparatus (15) on a first optometric measuring site (10); (b) carrying out at least one optometric measurement (16) of the wearer; (c) sending, to a second site (20), a digital measurement data set (18) including the optometric measurement result from step (b), the digital data set being linked, via computer, to the first record; and (d) digitally processing the optometric measurement result from the first record (14) on the basis of a digital data reference system (45) and the values of the respective identifiers of the glasses wearer and the optometric apparatus of the first record.
