Method for assessing the suitability between an optical device and a user of the optical device

A method, implemented by a computer, for assessing a suitability between an optical device and a user of the optical device, the optical device including at least an optical lens configured to be placed in front of at least an eye of the user when the user uses the optical device, the at least optical lens having a plurality of optical zones having different optical functions, the method comprising:

• requesting the user, equipped with the optical device, to use the optical device in a plurality of different visual situations, each of the visual situations being associated with an optical zone of the optical lens and during which the user looks at a visual target located in a natural environment of the user through the optical lens;
• receiving an assessed suitability index assessed by the user based on a use of the user of the optical device in the plurality of different visual situations;
• comparing the assessed suitability index to a predetermined threshold value;
• providing a recommendation to the user based on one or more of a result of the comparing and the evolution over time of the assessed suitability index, the provided recommendation provided to the user comprising data on how to suitably use the optical device;
• comparing the assessed suitability index to a critical threshold value when the assessed suitability index is lower than the predetermined threshold value;
• and
• providing an alert to one or more of the user and a professional based on the result of the comparing the assessed suitability index to the critical threshold value.
