Abstract

The invention is related to a process for producing contact lenses that not only comprise a water gradient structural configurations, but also have a minimized uptakes of polyquaternium-1 and a long-lasting surface hydrophilicity and wettability even after being undergone a simulated 30-days lens care regime.
