Abstract: The invention provides a method for evaluating at least one light protection level of at least one optical product intended to face an eye of a user, 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, - determining at least one long-term light protection score representative of at least one long-term light protection attribute, 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. The invention also provides an optical product comprising a frame, at least one optical system product attached to said frame and intended to face an eye of a user, a data collecting device and a controller configured to perform said evaluating method.
