Method for evaluating at least one light protection level of at least one optical product intended to face an eye of a user

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 evaluating at least one light protection level of said at least one optical product, the method comprising the following steps:

• 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, said at least one short-term light protection attribute is one among a transmission attribute, a polarization attribute, a stray light attribute and a spectral attribute;
• 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, wherein said at least one long-term attribute is a spectral attribute;
• determining at least two light environments, said at least two light environments are selected within a group of light environments, said group of light environments comprises at least one among a bright light environment, a day drive environment, a night drive environment, an indoor environment, a screen at night environment, an in-to-out transition environment and an out-to-in transition environment;
• selecting said at least one short-term light protection attribute and said at least one long-term light protection attribute respectively among a group of short-term light protection attributes and a group of long-term light protection attributes, depending on said at least two determined light environments;
• and
• evaluating at least one light protection level of said at least one optical product based on said at least one short-term and at least one long-term protection scores;
• wherein the step of evaluating at least one protection level comprises a step of determining at least one global light protection score of said at least one optical product based on said at least one short-term and at least one long-term light protection scores, wherein at least one short-term, at least one long-term and at least one global light protection scores are determined for each determined light environment.
