Disclosed herein is adjustable and/or modular augmented reality eyewear with a first viewing mode which optimizes a person's view of the real world and a second viewing mode which optimizes the person's view of virtual objects. The viewing mode is changed by moving a transflective mirror from a first location to a second location. The second location is closer to the center of the person's field of view than the first location. When the transflective mirror is in the person's field of view and reflects light from a display toward the person's eyes, then it displays a virtual object in the person's field of view.
