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 configured for myopia progression control in front of an eye, the optical system comprising:
a central zone that provides foveal vision correction; and
at least one of a paracentral zone and a peripheral zone, wherein at least one of the paracentral zone and the peripheral zone includes an integrated reticle and a reticle focuser, wherein the reticle focuser is arranged between the integrated reticle and a pupil of the eye, and thereby projecting an image of the integrated reticle onto at least one of a paracentral region and a peripheral region of a retina of the eye, to be perceived by the eye as within focus at the retina.
2. An optical system configured for myopia progression control in front of an eye, the optical system comprising:
a central zone that provides foveal vision correction; and
at least one of a paracentral zone and a peripheral zone, wherein at least one of the paracentral zone and the peripheral zone includes an integrated reticle and a reticle focuser, wherein the reticle focuser is arranged between the integrated reticle and a pupil of the eye, and thereby projecting an image of the integrated reticle onto at least one of a paracentral region and a peripheral region of a retina of the eye, to be perceived by the eye as myopically defocused at the retina.
3. The optical system of claim 2 , wherein the integrated reticle is active, thereby having light emitting capabilities.

19. The spectacle of claim 4 wherein the integrated reticle includes a plurality of micro-reticles.
20. The spectacle of claim 19 wherein the micro-reticles are aligned in at least one of a radial direction, a meridional direction and a circumferential direction relative to the pupil of the eye.
21. The spectacle of claim 19 wherein the micro-reticles are aligned in at least one of a radial direction, a meridional direction and a circumferential direction relative to the center of the spectacle lens.
22. The optical system of claim 2 further comprising a light source for lighting up the integrated reticle.
