Abstract: A rangefinder is incorporated into a pair of eyeglasses or sunglasses. A pair of holographic images, one including a distance-measuring scale and the other including a pointer, are projected separately into the eyes of a user, such that the images become superimposed over the user's field of view. As the user focuses on a distant object, the user's eyes move, and such movement causes the apparent position of the pointer, relative to the scale, to change. When the user has focused on the object, the pointer indicates a value which represents the distance of the object. The rangefinder can be used by golfers, hunters, surveyors, or the like, to provide a hands-free method of measuring distance.
