1. A contact lens, having:
a reduction in indentation force at an indentation depth of 400 nm, Δ(IF)400nm, of about 50% or larger;
a polyquaternium-1 uptake of about 0.40 micrograms/lens or less; and
a water-break-up time of at least 10 seconds and/or a friction rating of about 2.0 or lower after simulated abrasion cycling treatment,
wherein the contact lens comprises an anterior surface, an opposite posterior surface, and a layered structural configuration, wherein the layered structural configuration comprises, in a direction from the anterior surface to the posterior surface, an anterior outer hydrogel layer, an inner layer of a lens material, and a posterior outer hydrogel layer,
wherein the inner layer is a preformed contact lens essentially made of a silicone hydrogel material.
