  • Publication number: 20240037715
    Abstract: Methods, systems and devices for preventing and/or retarding myopia onset and/or progression are provided. Particularly, the system for preventing and/or retarding myopia onset and/or progression including an eye tracker, a display, a controller, and a dynamic blurring filter for the visual content on the display. The display is first presented to a subject, then the eye tracker is employed to detect the movement and the location of the subject's eyes and generate a tracking signal. The tracking signal is further processed by the controller to determine a gaze point of the subject's eye on the display. Based on the gaze point, a dynamic blurring filter is created and applied onto the display.

  • Publication number: 20220404639
    Abstract: Provided herein is concentric annular multi-zone lens for retarding myopia progression in a human eye. The lens comprises: a plurality of correcting zones for forming a focused image on a retina of the human eye so as to correct refractive error of the human eye, wherein the correcting zone having a similar refractive power; a plurality of defocusing zones for forming images anterior to the retina so as to generate myopic defocus; and a defocusing power increasing region, in which refractive powers of defocusing zones being increasingly relatively positive towards the periphery of the lens so as to generate larger amplitude of the myopic defocus at the periphery of the retina; wherein the plurality of correcting zones and the plurality of defocusing zones are alternated in the concentric annular multi-zone lens.

  • Patent number: 10898407
    Abstract: An optical system including a layer having a reflective surface, the layer is adapted to provide a primary image and a secondary image. The secondary image is provided by a reflection of an object facing the reflective surface, and the primary and the secondary images are viewable by a viewer having a retina. The secondary image is focused in front of the retina to generate myopic defocus.

  • Patent number: 10231897
    Abstract: A method for retarding or reversing progression of myopia of a viewer contains the steps of using an immersive or non-immersive device to create a plurality of image planes in the eye of the viewer. While an image plane is located on the retina, at least one image plane is not on the retina, thereby generating myopic defocus. Immersive and non-immersive devices and systems for such a method are also described.

  • Patent number: 9918894
    Abstract: A method for retarding or reversing progression of myopia of a viewer includes providing an object in front of the viewer; providing a transparent layer between the viewer and the object; and providing a primary image on the transparent layer, the transparent layer allows the viewer to see the object as a secondary image simultaneously with the primary image, wherein the secondary image is focused in front of the central region of the retina. A method for reducing hyperopia of a viewer includes providing an object in front of the viewer to provide a primary image; providing a transparent layer between the viewer and the object; providing a secondary image on the transparent layer, the transparent layer allows the viewer to see the primary image simultaneously with the secondary image, wherein the secondary image is focused behind the central region of the retina. Other systems are also described herein.
