Claim Text:
1. A method for treating an optical lens, comprising the following steps: providing an optical lens coated on at least one of the main surfaces thereof with a hydrophobic and/or oleophobic outer coating; depositing a temporary coating of polymeric nature comprising one or more layers onto the main surface of the lens so as to cover at least partially the hydrophobic and/or oleophobic coating, wherein a layer of the temporary coating is in direct contact with said hydrophobic and/or oleophobic coating and is formed by depositing onto said main surface of the lens a liquid coating composition, and then curing the liquid composition; and wherein, prior to the step of depositing the temporary coating onto the main surface of the lens, at least part of the peripheral area of the main surface coated with the hydrophobic and/or oleophobic coating is submitted to a treatment resulting in the removal of the coating in at least part of this peripheral area, and/or to the modification of the coating that lowers the hydrophobic character thereof, in at least part of this peripheral area, without affecting the hydrophobic and/or oleophobic coating on the main surface outside said peripheral area.
