  • Patent number: 11366338
    Abstract: Disclosed is a method for determining an optical system intended to equip a subject, the method including the steps of: —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—determining the optical system based on this index of sensitivity.

  • Publication number: 20210085172
    Abstract: A method of analyzing a visual field of an individual comprises the following steps:—measuring (S4) a first visual field (VF1) of said individual for a first set of oculo-postural parameters of said individual when said individual performs a first task;—measuring (S6) 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 (S8) a functional visual space based on said first visual field (VF1) 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.
