A spectacle lens can inhibit ametropia of the eyes and ensure full visibility. The spectacle lens comprises: first refraction areas and second refraction areas. Each first refraction area has a first refraction force that may be based on a prescription for correcting the ametropia of the eyes. Each second refraction area has a refraction force different from the first refraction force and may function to focus images on the positions except the retina of the eyes, to inhibit the development of the ametropia. Near the central part of the lens, the second refraction areas form a plurality of independent island-shaped areas, and the first refraction areas form the areas beyond the areas of the second refraction areas.

Spectacle lens

Spectacle lens and method of using a spectacle lens

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.

Methods and viewing systems for inhibiting ocular refractive disorders from progressing

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.

Methods, devices, and systems for inhibiting ocular refractive disorders from progressing

A method for treating progression of a refractive disorder in a human eye. The method includes the steps of producing a first image on a retina of the human eye and producing a second image to generate a defocus.

Lens for optical treatment

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.

A method for retarding the progression of myopia in a human eye, the method comprising: providing () a concentric annular multi-zone refractive lens including: at least one correcting zone of optical power for correcting () refractive error, and at least one defocusing zone for projecting () at least one non-homogenous defocused image in front of at least a part of retina to inhibit myopic eye growth, the at least one defocusing zone having at least one less negative power; wherein the correcting and defocusing zones are alternated () in the lens and the zones are connected () to each other through integrated progressive transition curves.
