Spectacles for use when aiming gun - incorporate mirrors attached to frame with one mirror being partly transparent
摘要
When aiming a gun at a target, one eye is used to look at the target whilst the other eye is closed and this closing of the eye often leads to irritation. Such irritation can be avoided using a special type of spectacles. The spectacles have a frame (1) with side pieces (2) to fit over the ears. A nose piece (4) is fastened to the middle of the frame (1). A mirror (8) is attached to the frame on one side of the nose piece and a partly transparent mirror (7) is attached to the frame on the other side of the nose piece. This arrangement enables the user to fix both eyes on the target. USE/ADVANTAGE - Spectacles for use when aiming a gun eliminate the need to shut one eye.
