Composite contact lens

The invention relates to a composite contact lens, which sequentially comprises a hydrophilic silicon-containing hydrogel layer and a hydrophilic hydrogel layer from the direction close to the eyeball surface to the direction away from the eyeball surface, wherein the hydrophilic silicon-containing hydrogel layer has oxygen transmittance of 60-180 equivalent and water content of 30-60 wt%. The present invention further provides a preparation method of the composite contact lens. According to the present invention, the composite contact lens has the hydrophilic silicon-containing hydrogel layer having the specific range of the oxygen transmittance and the specific range of the water content, such that the structure and the preparation process of the composite contact lens are simple, and the required specific range of the required water content can be maintained. 种复合隐形眼镜，由接近眼球表面至远离眼球表面的方向依序包含层亲水含硅水胶层及层亲水水胶层。该亲水含硅水胶层具备60至180当量的氧气透过率以及30～60wt％的含水量。本发明另提供该复合隐形眼镜的制法。本发明复合隐形眼镜由于含有该具备特定范围的氧气透过率及含水量的亲水含硅水胶层，因此得以让复合隐形
