| description | The invention belongs to the technical field of visual optics, and particularly relates to a holographic out-of-focus glasses device which comprises a glasses frame, lenses, a signal source and a plurality of holographic lenses. The signal source is arranged on the spectacle frame and is used for emitting light containing pattern information for correction to the lenses; the holographic film layer is arranged on the lens, and a plurality of holographic lenses are formed in the holographic film layer; and the plurality of holographic lenses are discretely distributed on the periphery of the central visual field area of the lens and are used for reflecting light rays containing pattern information for correction to form convergent light rays, so that a plurality of discrete pattern virtual images for correction are formed on the front side of the retina of a user, and defocus stimulation is formed. The holographic film layer in the holographic out-of-focus glasses device does not influence normal light imaging |
