Abstract
An apparatus for viewing a retroreflective object positions a light source proximate a human eye, by affixing it to, for example, a pair of goggles. The light source emits light outward in substantially the direction of view of the human eye. Upon striking a retroreflective object, the light is strongly reflected back to the human eye, producing a unique visual effect. The apparatus may be used in toy form to simulate a night vision scope. Various combinations of colored light sources, optical color filters interposed between the human eye and the retroreflector, and colored retroreflectors may be used to enhance the visual effect and increase the play variations available. The light source may switch on and/or off automatically, or may flash. Electronic light sensing means may provide a visible and/or audible alert when a retroreflective object is in view.
