| 摘要 |
The invention concerns binocular eyepieces which can be attached to spectacles, comprising a fixing frame 1 and two eyepieces 2, both of which have at least two lenses, of which the ocular lens on the eye side is smaller than the outer objective lens. An eyepiece casing 2' joining the lenses also widens at the outer surface in a sector angle which essentially corresponds to a sector angle drawn from the pupil to the edges of the ocular lens. The cross and longitudinal arms 3, 7, 9 of the frame have flexible hinges 4, 5, 12 made of a metal which can be shaped by bending. The eyepieces can be set precisely in accordance with the distance apart of the eyes of the user and restrictions in the field of view due to the eyepieces are minimized. <IMAGE>
