- (i) providing a lens blank having a first face, a second face opposite said first face, and an edge between said first face and said second face, said first face possessing a final curvature and being coated with an antireflection coating as an outer layer,
- (ii) blocking with the aid of a blocking material the lens blank on a block piece, wherein said first face of the lens blank faces said block piece,
- (iii) processing the blocked lens blank on said second face to obtain a processed lens,
- (iv) deblocking the processed lens from said block piece, and
- (v) applying on top of said antireflection coating on said first face of the processed lens a top coating selected from a group comprising at least one of hydrophobic, oleophobic or dust repelling coatings.
