Abstract

See full text

The invention relates to a method for treating an optical lens coated onto at least one of the main surfaces thereof with an outer hydrophobic and/or oleophobic coating, and for making it capable of undergoing an edging process, comprising a step of treating the peripheral area of said coated main surface which results in the removal of the hydrophobic and/or oleophobic coating and/or in the modification of said coating that lowers the hydrophobic character thereof, and a step of depositing a temporary polymeric coating onto said main surface of the lens so as to cover at least partially the hydrophobic and/or oleophobic coating and the peripheral area treated during the previous step, in order to provide an optical lens having onto at least one of the main surfaces thereof an outer hydrophobic and/or oleophobic coating and, in direct contact with said hydrophobic and/or oleophobic coating, a temporary polymeric coating adhering to the surface of the coated lens. The invention also relates to an edging method and to a lens capable of undergoing an edging process.
