摘要：
The invention concerns a method for treating an ophthalmic lens comprising two main sides and having at least one side comprising an organic or mineral external layer coated with a MgF 2 temporary protective layer, wherein treating comprises depositing the MgF 2 temporary protective layer on the external layer through vacuum evaporation at low speed, i.e. a speed lower than 0.5 nm/s. The invention also relates to an ophthalmic lens comprising a hydrophobic and/or oilophobic coating layer, which has been rendered apt to trimming by the deposition of a MgF 2 temporary protective layer on said hydrophobic and/or oilophobic coating layer using the above method.
