The invisible linear bifocal lens is a spherical or aspherical large-visual-field lens combined by spherical or aspherical technologies.

The invisible one-line double-light lens can be manufactured by adopting the modes of machining and forming by a precision machining center, injection molding by an injection molding machine, resin casting molding and the like.

The working principle of the invention is as follows: when the human eyeball crystal can not shrink freely, objects at different distances can not be presented on the retina of the human eyeball through zooming, and therefore the human eyeball crystal cannot be seen clearly. The lens replaces the zooming function of the eyeball to a certain extent, and the purpose of clearly showing objects at different distances on the retina is achieved.

By adopting the technical scheme, the invention has the beneficial effects that the two transition regions are arranged between the upper light region and the lower light region, so that the problems of image jump and image mutation can not occur when the sight is switched from far vision to near vision or from near vision to far vision, the areas of the upper light region and the lower light region are large, the range is wider, and the sight is clear; the upper light area and the lower light area adopt flat arc and circular arc transition, so that the lens is not obvious in projecting feeling and has no difference with the common lens in appearance.
