摘要:Curve lens curve lens manufacturing method is described. The one embodiment for manufacturing the method for curve lens includes: that curved lens hair is bad, and multiple polymeric layers are laminated by linear polarizer layer together. The lens blank, which curves through, does not generate rotary motion, around the surface of rotation axis rotating roller, and there is the transverse movement belt in being formed thereon to contact to form surface. The lens blank, which is heated, forms pressure between press belt and surface, which is the tension by belt. It keeps pressure to be enough that the shape of lens blank is made to be consistent for a period of time, forms surface. The curve lens that method of the invention can be used for having different polarized light properties and curvature to manufacture.
