Anti-myopia-progression spectacles and associated methods
Spectacles that control myopia progression have a central zone that achieves foveal vision correction and distributed micro-reticle(s) and corresponding micro-lens(es) around the paracentral and/or peripheral zone of the spectacle. Each micro-lens is disposed between its corresponding micro-reticle and the pupil of a wearer's eye. The micro-reticle(s) and micro-len(s) are integrated with the structure of the spectacle to partially block some of the paracentral and/or peripheral objects from surrounding optical environment. The rest of the paracentral and/or peripheral retinal areas are still available for a wearer's eye to sense the presence and movement of surrounding objects.
1. An optical system for myopia progression control by placement in front of an eye, wherein the optical system includes a central zone and at least one of a paracentral zone and a peripheral zone, the optical system comprising of:
a first integrated reticle located on the at least one of the paracentral zone and the peripheral zone of the optical system;
a corresponding first reticle focuser located on the at least one of the paracentral zone and the peripheral zone of the optical system, wherein the first reticle focuser is configured to be located between the first integrated reticle and a pupil of the eye, and thereby capable of projecting an image of the first integrated reticle onto at least one of a paracentral region and a peripheral region of a retina of the eye, wherein the image of the first integrated reticle is within a band of longer wavelengths of a visible light spectrum, and wherein the image of the first integrated reticle is to be perceived by the eye as within focus at the retina;
a second integrated reticle located on the at least one of the paracentral zone and the peripheral zone of the optical system; and
a corresponding second reticle focuser located on the at least one of the paracentral zone and the peripheral zone of the optical system, wherein the second reticle focuser is configured to be located between the second integrated reticle and the pupil of the eye, and thereby capable of projecting an image of the second integrated reticle onto the at least one of a paracentral region and a peripheral region of the retina of the eye, wherein the image of the second integrated reticle is within a band of shorter wavelengths of the visible light spectrum, and wherein the image of the second integrated reticle is to be perceived by the eye as myopically defocused at the retina, thereby retarding myopia progression of the eye.
