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.
