The invention is generally related to soft contact lenses which comprise a non-silicone hydrogel lens body and a hydrogel coating thereon. The non-silicone hydrogel lens body is composed of a hydrogel material which is free of silicone and comprises at least 50% by mole of repeating units of at least one hydroxyl-containing vinylic monomer. The hydrogel coating comprises a first polymeric material having first reactive functional groups and a hydrogel layer derived from a second polymeric material having second reactive functional groups, and the hydrogel layer is covalently attached onto the anchor layer through linkages each formed between one first reactive functional group and one second reactive functional group. The soft contact lens has a surface lubricity better than the lubricity of the non-silicone hydrogel lens body and has a friction rating of about 2 or lower after 7 cycles of manual rubbing, a water content of from about 10% to about 85% by weight and an elastic modulus of from about 0.2 MPa to about 1.5 MPa when being fully hydrated at room temperature.
