Abstract:
An ophthalmic lens material comprises a hydrophilic monomer, a clay, a cross-linking agent, an initiator, and a solvent. The hydrophilic monomer has a mass percentage of about 40% to about 65% of a total mass of the ophthalmic lens material. The clay has a mass percentage of about 0.1% to about 3% of the total mass of the ophthalmic lens material. The cross-linking agent has a mass percentage of about 0.15% to about 2% of the total mass of the ophthalmic lens material. The initiator has a mass percentage of about 0.11% to about 1.05% of the total mass of the ophthalmic lens material. The solvent has a mass percentage of about 30% to about 58% of the total mass of the ophthalmic lens material. The disclosure also provides an ophthalmic lens made of the ophthalmic lens material.
