example 1

[0119] Example 1: Ambiguity Tolerance

[0120] Individual reference visual parameter assessment:

[0121] This reference assessment aims to provide information about the individual's reference visual and / or visuomotor behavior and to enable the effectiveness of adaptations to be judged through training.

[0122] 1. Ambiguity tolerance: A first measurement is made to inform the reference level of the individual's ambiguity tolerance.

[0123] 2. Frequency Preference: Calculate the visual pattern (also known as blended image) considering the distance from the screen. In the sense of the invention, a mixed image has both low and high spatial frequencies, but the low and high spatial frequencies come from different scenes / images, the high SF of one image / scene is compared to the low SF of the other scene / image. SF combination.

[0124] The individual is presented with a set of 2N images having N blended images and N non-blended images. For example, N=36 and the unblended i...

[0153] Example 2: Eye-head coordination

[0154] Individual reference visual parameter assessment:

[0155] This reference assessment aims to provide information about the individual's reference visual and / or visuomotor behavior and to enable the effectiveness of adaptations to be judged through training. For example, a personal reference visual parameter assessed is the eye-head coefficient (COT). In fact, it is known that individuals have different tendencies to move their eyes or their head when successively looking in different directions. This tendency can be important when producing ophthalmic lenses. For example, as disclosed in US 2010 / 0002191, when producing ophthalmic lenses, this tendency can be taken into account in order to determine the compromise between correction of foveal vision and correction of peripheral vision. The eye-head coefficient correlates with this tendency, and thus with the range of motion of the wearer's eyes and head.

[0172] Example 3: Sensitivity to Distortion

[0173] Individual reference visual parameter assessment:

[0174] This reference assessment aims to provide information about the individual's reference visual and / or visuomotor behavior and to enable the effectiveness of adaptations to be judged through training. For example, an individual's reference visual parameter that is assessed is the individual's sensitivity to distortion.

[0175] A method for assessing a user's sensitivity to distortion is disclosed inter alia in WO 2016 / 055 265.

[0176] Reference measurements of sensitivity using immersive viewing devices, virtual reality headsets, and more. For the measurements, individuals are positioned in a simulated visual environment where distortions can be added in a controlled manner. Reference measurements are then made to determine the effect of distortion on an individual's visual and / or visuomotor behavior (such as object grasping, balance, walking, obstacle travers...

Abstract

The invention relates to a method for adapting the visual and / or visual-motor behaviors of a person. The method comprises an optical parameter and a person visual parameter providing step (S2, S4), during which a person visual parameter indicative of a visual parameter of the person relative to a given visual and / or visual-motor behavior of the person is provided and an optical parameter characterizing an optical system is provided, and the optical system is intended to equip the person; a target value providing step (S6), during which a target value for the person visual parameter related tothe optical parameter is provided; a visual and / or visual motor behavior modifying step (S8), during which a reference visual and / or visual-motor behavior of the person is modified so as to define a modified visual and / or visual-motor behavior of the person by providing a visual and / or visual-motor training to the person; a person visual parameter assessing step (S10), during which the person visual parameter is assessed for the modified visual and / or visual-motor behavior of the person; a determining step (S12), during which a suitable visual and / or visual-motor behavior for the person equipped with the optical system is determined by repeating the modifying and assessing steps so as to minimize the difference between the assessed person visual parameters and the target value; and an adapting step (S14), during which the visual and / or visual-motor behavior of the person equipped with the optical system is adapted based on the suitable visual and / or visual-motor behavior.

Description

technical field [0001] The present invention relates to a method and system for adapting the visual and / or visuomotor behavior of an individual. The invention also relates to a computer program product comprising one or more stored sequences of instructions accessible to a processor and which, when executed by said processor, cause Said processor implements the steps of the method according to the invention. Background technique [0002] Ophthalmic lenses intended to be secured in spectacle frames usually involve a prescription. Ophthalmic prescriptions may include plus or minus power prescriptions as well as astigmatism prescriptions. These prescriptions correspond to corrections that enable the wearer of the lens to correct his vision defects. The lenses are fitted in the spectacle frame according to the prescription and according to the position of the wearer's eyes relative to the spectacle frame. [0003] For presbyopic wearers, the power correction values ​​for dis...
