Abstract
The invention provides a method for determining at least one filter for a transparent support, the method comprising the following steps: —determining a quantity representative of a light sensitivity threshold of the user; —determining, for each light environment among a group of light environments, an index representative of the level of protection required by the user; —determining a score for each light environment among the group of light environments (40) and for each filter among a group of filters, said score being representative of the capacity of the filter to reach the level of protection required by the user, determining at least one filter among the group of filters based on the scores of said at least one filter in a plurality of light environments (40) among the group of light environments.
