Optical products are disclosed that include a polymer substrate; a composite coating, deposited on the polymer substrate; a permeating adhesive, which permeates the composite coating and is in contact with the polymer substrate; and a protective layer, secured to the composite coating by the permeating adhesive. The composite coating includes at least a first layer and a second layer, each of which is provided with a binding group component which together form a complementary binding group pair. The optical products exhibit improved resistance to delamination during storage and use.
