Abstract
A wetness-retaining ophthalmic lens material comprises an organic monomer, a cross-linking agent, an initiator, a salt, and a solvent. The salt dissolves in the water dissociates a plurality of anions and cations, which bind to water molecules and retard the evaporation of the water molecules, the ophthalmic lens material thus can keep wet for a long time. An ophthalmic lens made of the ophthalmic lens material is also provided.
