Abstract:
The present invention provides a hybrid soft contact lens including a central portion formed with a first hydrous soft material, and a peripheral portion formed with a second hydrous soft material, in which the first hydrous soft material is obtained by curing a first curable composition including a silicone-containing monomer. Preferably, the first hydrous soft material has a Young's modulus of no less than 3.0 MPa and no greater than 100 MPa, and the second hydrous soft material has a Young's modulus of no less than 0.20 MPa and less than 3.0 MPa.
