A wearer adjustable apparatus is configured for a wearer to view an object and adjust stimuli projected into the eye by adjusting the location of the projection optics, for example with movement of the projection optics relative to one or more components of a support such as an eyeglass frame. In some embodiments, the projection system comprises an adjustable retainer for the wearer to adjust first active projection elements coupled to a first support in front of a first eye in relation to second projection optics coupled to a second support in front of a second eye of the wearer. In some embodiments, the apparatus comprises oculars comprising the projection optics and corrective lenses configured for the wearer to adjust positions of the lenses and projection optics in front of the wearer's eyes in order to project therapeutic spots onto a desired location relative to the wearer's retinas.
