  • Patent number: 4353621
    Abstract: Embodiments of optical toys for reversing sighted images are used by individuals for their personal enjoyment and their enjoyment with others in playing games. When these toys are held closely adjacent to their eyes and then, while viewing the reversed scene before their eyes, they try to maneuver ahead, for example, to follow a reversed curved pathway. In a preferred embodiment, two right angle solid optical prisms are mounted in spaced relationship on a hand held housing, so one prism is opposite each eye, with one of its right angle sides positioned at a forty-five degree angle flaring outwardly, as its hypotenuse side is pointed directly ahead of the person. In another embodiment, instead of the solid optical prisms, multiple angled interconnected reflective surface units are arranged before each eye and they are respectively supported on an eyeglass-like frame. A timing device may be inserted in the housing when games are played in accordance with a preset game time period.
