Abstract
The invention is related to a coated contact lens, especially a coated silicone hydrogel contact lens, which comprises an anterior surface, an opposite posterior surface, and a layered structural configuration from the anterior surface to the posterior surface. The layered structural configuration comprises an outer anterior surface hydrogel layer, an inner layer, and an outer posterior surface hydrogel layer. The inner layer is a lens bulk material. The coated contact lens has a superior lens surface softness and a good lens surface hydrophilicity while optionally having a desirably-lower polyquaternium-1 uptake.
