Abstract: A system for determining a modification or a change of an initial myopia control solution used by a myopic subject, including a device for determining a real initial value and real ulterior value of an eye state parameter representative of the myopia degree of the eye of the subject at an initial time and at an ulterior time, one or more memories having in memory statistical data relative to the statistical evolution of the eye state parameter with time while the initial myopia control solution is implemented, one or more processors programmed to determine an expected ulterior value of a magnitude linked to the eye state parameter at the ulterior time based on the statistical data relative to the statistical evolution of the eye state parameter with time while the initial myopia control solution is implemented.

Abstract: A system for determining an appropriate moment for modifying or changing an initial myopia control solution used by a myopic subject at an initial time having a database of available myopia control solutions and data relative to the evolution of the efficacy of each myopia control solution with criterion including determining the value of said criterion at an ulterior time, determining, based on this value, the efficacy of this initial myopia control solution and the efficacy of other myopia control solutions of said database at this ulterior time, comparing the efficacy of said initial myopia control solution and the efficacy of other myopia control solutions of said database determined for said ulterior time, and when the efficacy of said initial myopia control solution is lower than the efficacy of at least one of said other myopia control solutions at said ulterior time, determining appropriate moment depending on said ulterior time.

Abstract: An adjustment device (100; 100?; 100?) for adjusting the length of a bracelet, having at least one adjustment assembly (10; 10?; 10?) movable relative to a clasp cover (7; 7?; 7?), the adjustment assembly and the cover being respectively provided with a first and a second fixing element (11, 71; 11?, 71?; 11?, 71?) for their respective fixing according to several positions capable of inducing different bracelet lengths, and also being provided respectively with a first and a second indexing element (21, 72; 21?, 72?; 21?, 72?) for their temporary respective positioning according to one of the several positions, the adjustment assembly (10; 10?; 10?) also comprising a guiding device including a first guiding element (3, 4, 5; 3?, 4?, 5?; 3?, 4?) cooperating with a second guiding element (74; 74?; 74?) of the cover (7; 7?; 7?) to guide the displacement of the adjusting assembly (10; 10?; 10?) relative to the cover (7; 7?; 7?), the first indexing element (21; 21?; 21?) being independent of and/or distinct from t

Abstract: An aspect of the disclosure relates to a method of determining an attitude of an eyewear. The method may include: detecting a light signal reflected from the eyewear with a digital device including a light sensor for a non-visible wavelength range; and calculating, using the light signal, an attitude of the eyewear. The attitude may be at least one of: a yaw angle, a pitch angle, a roll angle. A second aspect of the disclosure relates to an eyewear including at least a first lens. The first lens may include a first coating having reflection in the non-visible range of wavelengths. The first coating may further include a pattern with an orientation. A third aspect of the disclosure relates to a computer program product including instructions, which, when the program is executed by a digital device, causes the digital device to carry out the method.

Abstract: A case for a timepiece having a middle, a rotating bezel, and a device for blocking the rotating bezel, the device including an end-link, mounted mobile relative to the middle between a first position capable of preventing the rotation of the rotating bezel and a second position capable of allowing the rotation of the rotating bezel, the end-link including an action and/or gripping portion arranged so as to allow the wearer of the timepiece to move the end-link relative to the middle, while wearing the timepiece.

Abstract: A method for calculating or optimizing an ophthalmic lens design comprising the steps of providing a given ophthalmic lens design and assessing the given design by a computer comprising a media suitable for storing electronic instructions.

Abstract: A method implemented by computer means of assessing at least a selected optical feature of an ophthalmic lens design over a prescription and optionally design particularity domain comprising the steps of: a) selecting a prescription and optionally design particularity parameter set comprising a plurality of prescription parameters in the list consisting of spherical power (SPH), cylindrical power (CYL), cylinder axis (AXE), addition power (ADD) and selecting a prescription and optionally design particularity range for each selected prescription and optionally design particularity parameter so as to define the prescription and optionally design particularity domain; b) meshing the prescription and optionally design particularity domain so as to provide a plurality of meshing coordinates; c) providing an assessment criterion for the selected optical feature of the ophthalmic lens design; d) calculating the assessment criterion value for each meshing coordinate of step b); e) providing a sensory represent
