OPHTHALMIC LENS HAVING DIFFERENT ANTI-FOULING PROPERTIES ON EACH OF THE TWO SURFACES THEREOF AND MANUFACTURING METHODS

摘要

The present invention relates to an ophthalmic lens in which the front and rear surfaces each have different hydrophobic properties. Said lens includes a substrate having a hydrophobic main front surface, and a main rear surface, the outer surface of which has a receding water contact angle of no lower than 80°, the outer surface of said main front surface having a receding water contact angle lower than that of the rear main surface. The invention provides various means for preparing said lenses, which can be obtained in particular after depositing and then removing temporary layers with different thicknesses on the two surfaces of the lens.
