A method of analyzing a visual field of an individual comprises the following steps: —measuring (S) a first visual field (VF) of said individual for a first set of oculo-postural parameters of said individual when said individual performs a first task; —measuring (S) 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 (S) a functional visual space based on said first visual field (VF) 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.

A method for determining an optical design criterion for designing an optical lens adapted to a sport practice, the method including: defining an evaluation axis for evaluating sensory/motor/cognitive requirement of a sport practice, for each of a plurality of sports; attributing a score to the sport practice on each evaluation axis; determining clusters of sports in which practices have similar score; determining at least one visual need corresponding to each cluster of sports; determining, for each cluster, at least one optical design criterion as a function of the associated visual need; and storing in a memory a record for each cluster, along with each optical design criterion associated with the cluster.

The invention relates to an optical device () adapted to be worn by a wearer comprising at least: &#x2014;a programmable lens () having an adjustable optical function and extending between at least one eye of the wearer and the real world scene when the optical device is worn by the wearer, &#x2014;an optical function controller () comprising &#x2014;a memory () storing at least computer executable instructions; and &#x2014;a processor () for executing the stored computer executable instructions so as to control the optical function of the programmable lens (), wherein the computer executable instructions comprise instructions for adjusting the optical function of the programmable lens () over a period of time determined so that the wearer does not perceive the adjustment of the optical function.

The invention relates to a method for determining a progressive ophthalmic device for personalised visual compensation for an individual, according to which the following steps are performed: a) in a first data acquisition phase, determining at least at a first time preceding the appearance of the presbyopia of this individual, at least one value of at least one individual parameter of said individual, and recording each value of the individual parameter of the wearer in a database, in correlation with an associated temporal indicator, b) in a second determination step of the progressive ophthalmic device for personalised visual compensation, determining a desired value of at least one geometric or optical parameter of said progressive ophthalmic device for visual compensation, taking account of said at least one value of the individual parameter determined in step a) and the associated temporal indicator.

A method for determining an ophthalmic lens adapted to a wearer, including: providing wearer data including at least an indication of a prescription of the wearer; providing a locomotion scenario including at least an input locomotion parameter and visual environment data indicative of a visual environment, the locomotion parameter including at least movement data indicative of at least translation movements of the wearer's head; providing an output parameter of a locomotion parameter of the wearer or an optical parameter of the ophthalmic lens having an impact on a locomotion parameter of the wearer; determining an ophthalmic lens adapted to the wearer based at least on the wearer data to have the output parameter as close as possible to the target value of the output parameter when carrying out the locomotion scenario using the ophthalmic lens, wherein the output parameter is retinal flow of the wearer.

Disclosed is a method for determining an optical system intended to equip a subject, the method including the steps of: &#x2014;determining an index of sensitivity indicating, when the subject is placed in an environment including surfaces and/or borders forming globally a geometry of this environment; and landmarks associated with specific locations within the environment, how the subject relies on the global geometry and/or on the local landmarks of the environment to navigate within the environment; and&#x2014;determining the optical system based on this index of sensitivity. The invention also relates to an ophthalmic lens and to an ophthalmic filter determined by such method.

Disclosed is a method for determining at least one visual behavior parameter of a person. The method includes the following steps: a step of encouraging the person to perform a visual test during which he observes at least one target position, a step of measuring an item of data that is representative of at least one viewing direction of the person during the visual test, a step of determining a reference viewing direction on the basis of the representative data measured, and a step of positioning, relative to the reference viewing direction, at least one measured target position that is determined, in a reference marker associated with the head of the person, on the basis of the data that is representative of the viewing direction of the person measured during the visual test.
