Abstract: Method for determining a refraction of at least an eye of a person under specific spectral conditions, the method including: an eye illumination step, during which the eye of the person is illuminated under the specific spectral conditions, the specific spectral conditions being provided by a polychromatic source having a spectrum which is different from the spectrum of a white light source and/or by a chromatic filter positioned before the eye of the person and illuminated by a source; and a refraction determination step during which the refraction of the eye of the person is determined under the specific spectral conditions.

Abstract: Disclosed is a method for determining a filter for an ophthalmic lens to be placed in front of the eye of the wearer, the filter being able to improve or maintain the visual comfort and/or the visual performances of the wearer. The determination method includes: a step of measuring a variable representative of sensitivity of the eye or both eyes of the wearer to a characteristic light flow, and a step of determining at least one optical characteristic of the filter according to the representative variable measured.

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. The invention also relates to an ophthalmic lens and to an ophthalmic filter determined by such method.

Abstract: A device for simulating a behavior of a mammal in an environment by a virtual mammal includes a mobile head and at least one mobile eye including a first input for successive data representative of eye poses, a second input for mobility action instructions, a memory for storing information on the environment and on stabilization constraints, at least one processor assessing a current part of the environment and recording information on said current part, triggering successive movements of the head and of the eye(s) in function of said mobility action, controlling a dynamic adjustment of the successive movements of the eye(s) with respect to the successive movements of the head in function of the successive data and by using the stabilization constraints. The device further comprises a third input for training data representative of a training movement sequence of the head and the eye(s) associated with a training environment.

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.

Abstract: The invention relates to a method for determining a filter for an ophthalmic lens intended for being placed in front of the eye wearer, said filter being capable of improving or maintaining the visual comfort and/or the visual performance of said wearer. According to the invention, this method includes: a) a step of determining a quantity representing a dynamic sensitivity of the eye or the two eyes of the wearer to a variation in a luminous flux; and b) a step of determining at least one optical feature of said filter as a function of the determined representative quantity.

Abstract: The invention relates to a device (10) for assessing discomfort glare and/or disability glare of a subject, comprising: —at least one neuro-sensor (11) for detecting a neural signal linked to the sensitivity of the eyes of the subject, —a control unit (15) adapted to a) record the neural signal of the subject detected by the neuro-sensor while at least one eye of the subject receives a given light condition, b) provide a threshold neural signal that is characteristic of a shift for the subject from no-glare state to discomfort glare and/or disability glare, c) assess whether the neural signal recorded in step a) correlates with a discomfort glare and/or disability glare of the subject by comparing said neural signal recorded in step a) to said threshold neural signal provided in step b). The invention also relates to an eyeglass comprising said device, to a method for assessing discomfort glare and/or disability glare of a subject, and to a virtual reality headset comprising the device.

Abstract: Disclosed is a method for determining a filter for a visual equipment to be placed in front of the eye of a user to improve visual comfort and/or visual performance of the user, the method including: determining the spectral transmittance of an ocular media of an eye; and determining a filter based on the determined spectral transmittance of the ocular media so the filter has a spectral transmittance profile including: a first portion having a maximum transmittance value between 380 nm and a predetermined threshold, and a second portion with a decreasing transmittance value between the threshold and 670 nm. Also disclosed is a filter whose spectral transmittance is calculated based on the spectral transmittance of the user's ocular media, as well as a set of filters with each filter in the set having a spectral transmittance based on the spectral transmittance of the ocular media of users having different ages.
