    摘要: The invention relates to a process for rendering contact lenses hydrophilic, which comprises treating a contact lens with a compound of formula IAr--Z--Ar' (I)wherein Ar and Ar' are each independently of the other an aromatic radical that may be substituted by lower alkoxy and/or by lower alkyl and wherein one of the radicals Ar and Ar' or both radicals Ar and Ar' contain one or more substituents X selected independently of one another from a polar functional group Y, lower alkyl substituted by a polar functional group Y, and lower alkoxy substituted by a polar functional group Y, and wherein Z is a divalent group that separates Ar and Ar' from each other by from one to six atoms. The invention relates also to contact lenses treated according to the invention and to the use of compounds of formula I in the process according to the invention.
