ABSTRACT:
The present invention relates to a process for treating an ophthalmic lens comprising two main sides the first one of which comprises a thin external organic or inorganic layer, comprising:—at least one treatment step for the second lens side through energetic and/or reactive species capable to perform a surface physical attack and/or chemical modification,—in option, at least one or more steps for depositing inorganic or organic layers carried out simultaneously or subsequently to the treatment step through said energetic and/or reactive species, characterized in that before the treatment step through energetic and/or reactive species, a deposition of a temporary protective layer is performed onto the thin external organic or inorganic layer. Application to ophthalmic optics.
