Abstract
Systems, devices, apparatuses and methods for an active projection system that may be incorporated into spectacles, contact lenses or provided as an add-on layer to existing spectacles or lenses. The active projection system operates to generate a stimulus or stimuli for viewing by a person's eye. The stimulus or stimuli creates an image that is defocused in front of the person's retina and can assist in slowing or stopping the progression of myopia or other refractive errors in the person.
