Abstract
The invention provides a cost-effective and in-situ method for applying an LbL coating onto a silicone hydrogel contact lens directly in a lens package. The resultant silicone hydrogel contact lens has a coating with good hydrophilicity, intactness and durability and also can be used directly from the lens package by a patient without washing and/or rising. In addition, the invention provides a packaging solution for in-situ coating of a silicone hydrogel contact lens in a lens package and an ophthalmic lens product.
