Glasses for viewing two scenes simultaneously
摘要:
An optical device that reflectively superimposes a virtual image of an object viewed in one direction on a transparent lens member through which a second object may simultaneously be viewed in a second direction. The optical device comprises a transparent member and reflecting member adapted to reflect the image of an object onto the transparent member where it may be viewed by a person looking through the transparent member at another object. The reflecting member preferably is adapted to receive the face of the person utilizing the device and defines a nose bridge and cheekbone pockets for that purpose.
