Method for determining at least one optical product intended to face an eye of a user using an eye resistance level and a light protection level

A method for determining at least one optical product intended to face an eye of a user, the method comprising the following steps:

• determining at least one light protection need of a user by performing the method for determining a visual discomfort and/or a visual performance of a user according to any one of the preceding claims;
• determining at least one short-term light protection score representative of at least one short-term light protection attribute of said at least one optical product;
• determining at least one long-term light protection score representative of at least one long-term light protection attribute of said at least one optical product;
• evaluating at least one light protection level of at least one optical product based on said at least one short-term and at least one long-term protection scores;
• and
• determining at least one optical product for the user based on said at least one light protection level and said at least one light protection need of the user.

A computer system for determining a visual discomfort and/or a visual performance of a user, the system comprising:

• a processor;
• and
• a memory with computer code instructions stored thereon, the memory operatively coupled to the processor such that, when executed by the processor, the computer code instructions cause the computer system to perform a method for determining at least one optical product intended to face an eye of a user, the method comprising the following steps:
• determining at least one light protection need of a user by:
• providing at least two quantities representative of a light sensitivity threshold of the user;
• and
• determining a resistance level based on said at least two quantities representative of a light sensitivity threshold of the user using a percentile scale based on a population baseline;
• determining at least one short-term light protection score representative of at least one short-term light protection attribute of said at least one optical product;
• determining at least one long-term light protection score representative of at least one long-term light protection attribute of said at least one optical product;
• and
• evaluating at least one light protection level of at least one optical product based on said at least one short-term and at least one long-term protection scores.

An optical product comprising a frame and at least one optical system attached to said frame and intended to face an eye of a user, said optical product comprising a data collecting device and a controller configured to perform a method for determining at least one optical product intended to face an eye of a user, the method comprising the following steps:

• determining at least one light protection need of a user by:
• providing at least two quantities representative of a light sensitivity threshold of the user;
• and
• determining a resistance level based on said at least two quantities representative of a light sensitivity threshold of the user using a percentile scale based on a population baseline;
• determining at least one short-term light protection score representative of at least one short-term light protection attribute of said at least one optical product;
• determining at least one long-term light protection score representative of at least one long-term light protection attribute of said at least one optical product;
• evaluating at least one light protection level of at least one optical product based on said at least one short-term and at least one long-term protection scores;
• and
• determining at least one optical product for the user based on said at least one light protection level and said at least one light protection need of the user.
