Beschreibung
Zusammenfassung:	The present invention relates to an ophthalmic lens whose front and rear faces are differentiated with respect to their hydrophobic properties. Said lens comprising a substrate having a hydrophobic front main face, and a rear main face whose external surface has a receding contact angle with water greater than or equal to 80°, the external surface of said front main face having a receding contact angle with water lower than that of the rear main face. The invention presents various means for preparing such lenses, which may notably be obtained after deposition and then removal of temporary layers with different thicknesses on the two faces of the lens.
