摘要： A device for evaluating the performance of visual equipment for a wearer. The device includes at least one input adapted to obtain virtual tests to be performed with the equipment, each test including at least one scenario combined with at least one virtual model of the wearer, defining how a visual task including a sequence of fixation points is to be carried out by the model in an environment defined by a description of shapes and positions of elements to be viewed by the model, at least one processor configured for selecting at least one test, based on at least one personalized real or simulated wearer activity profile representing usage of the equipment by the wearer, and evaluating the performance of the equipment with which the selected test is performed by the model by computing for one or more fixation points at least one performance criterion generated for the task.

摘要： A device for evaluating visual equipment models corresponding to real visual equipments. The device includes at least one input adapted to obtain parameters including a prescription for a given human wearer of any one of the real visual equipments, a set of ophthalmic lenses pre-selected on the basis of those parameters, at least one processor configured, for each pre-selected ophthalmic lens, to obtain a visual equipment model including a virtual ophthalmic lens defined by the same characteristics as the pre-selected ophthalmic lens, obtain a wearer model from the parameters, the visual equipment model cooperating with the wearer model, obtain an environment and visual task model including a sequence of points to be looked at by the wearer model, and evaluate a performance of the visual equipment model worn by the wearer model and combined with the environment and visual task model.

摘要： A method for determining at least one optimized visual equipment to be worn by a human wearer includes: obtaining a wearer model as a virtual model of the human wearer; obtaining a model of at least one environment for which the at least one optimized visual equipment is to be determined, the at least one environment comprising tridimensional positions of objects to be viewed by the wearer model; determining at least one evaluation function related to the visual equipment, as a function of at least optical performance of the visual equipment and postural performance of the wearer model in the model of the at least one environment; optimizing the at least one evaluation function, so as to determine the at least one optimized visual equipment.

摘要： 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.
