A cross-linked hydrophilic coating comprising a cross-linked hydrophilic polymer, wherein the coating comprises a prepolymer containing reactive sites cross-linkable through polymerisation of vinylic unsaturated groups and optionally one or more saturated polymers cross-linked through vinylic groups may be cross-linked by UV radiation. The hydrophilic coatings of the invention has a high abrasion resistance giving the devices a long life time.
