A system and method for determining an adapted ophthalmic device for a wearer, the method including acquiring a set of parameters values relating to the wearer, determining at least a task to be performed by the wearer involving visual exploration, using a computing system, determining a value of a criterion assessing an efficiency of the wearer's visual exploration strategy for the task, and determining an optical design of an ophthalmic device to be worn by a wearer according to the determined value of the criterion.

Method for adapting ophthalmic equipment according to a wearers visual exploration strategy

A method for determining an optical system intended to equip a person on the basis of the adaptability of the person to a visual and/or proprioceptive modification of his environment, the method including a person visual behaviour parameter providing, during which a person visual behaviour parameter indicative of the visual behaviour of the person relative to a given state of the environment is provided; a reference value providing, during which a first value of the person visual behaviour parameter corresponding to a reference state of the environment is provided; a visual and/or proprioceptive modification providing, during which a visual and/or proprioceptive modification of the reference state of the environment is provided so as to define a modified state of the environment; and determining, during which an optical parameter of the optical system is determined based on the first value of the person visual behaviour parameter and on a second value of the person visual behaviour parameter associated with the modified state of the environment.

A method for determining an optical system intended to equip a person on the basis of the adaptability of the person to a visual and/or proprioceptive modification of his environment, the method. including a person visual behaviour parameter providing, during which a person visual behaviour parameter indicative of the visual behaviour of the person relative to a given state of the environment is provided; a reference value providing, during which a first value of the person visual behaviour pa ameter corresponding to a reference state of the environment is provided; a visual and/or proprioceptive modification providing, during which a visual and/or proprioceptive modification of the reference state of the environment is provided so as to define a modified state of the environment; and determining, during which an optical parameter of the optical system is determined based on the first value of the person visual behaviour parameter and on a second value of the person visual behaviour parameter associated with the modified state of the environment.

Method for measuring the visually-induced postural instability of a person is described, the method comprising a display providing step (S) during which a visual display device is provided. The display device is arranged so as to display a dynamic visual pattern in at least 50% of the lower half of the visual field of the person, leaving an upper half of the visual field of the person free. The method also comprises a display step (S) during which a dynamic visual pattern is displayed on the visual display device. The method further comprises a measuring step (S) during which a parameter representative of the postural instability is measured when the person is gazing at a fix target straight in front while having the dynamic visual pattern displayed on the visual display device.

Method for determining the relative amplitude of eye and head movements of an individual, comprising: &#x2014;a target providing step during which a list of visual targets comprising at least two different visual targets is provided; &#x2014;a reference positioning step; &#x2014;a reference target providing step during which a reference target comprising a visual and auditory target is provided; &#x2014;a reference target gazing step during which the individual gazes at the reference target; &#x2014;a peripheral target providing step during which a peripheral target comprising a visual and auditory target is provided; &#x2014;a peripheral target gazing step during which the individual gazes at the peripheral target; and, &#x2014;a rotation measurement step during which the angle of rotation of the individual's head and the angle or rotation of the individual's eyes are measured.
