Note: In addition to the license you give Facebook (check out Facebook’s Terms), when you post content or information to the Ray-Ban fan page you grant Luxottica Group S.p.A. and its affiliates a royalty-free, perpetual, global license to use what you post in any medium (i.e. not just the Internet or Facebook), for any and all purposes (advertising, marketing, promotion, etc.) without restrictions or obligations. This means if we like your stuff we might share it with others and since you offered it up, its free to use.
