Abstract:
An optical lens includes: (i) a temporary coating for protection against degradation at least partially covering a surface of the lens, the temporary protective coating including an outermost layer mechanically degradable through friction and/or contact, and (ii) a removable film having a first side and a second side, which adheres to the outermost layer of the temporary protective coating through its first side, the first side of the removable film including at least one surface portion, which, when applied to the outermost layer of the temporary protective coating, includes at least one adherent zone and at least one non-adherent zone distributed across the surface portion.
