| Abstract: |
An anti-dazzling device relating to eye protection for drivers driving at night comprises a fixing means, a shield, and an adapter means, in which the fixing means can be fixed adjustably in tightness to the head of a user, the adapter means extends forward from the fixing means, the shield is connected to the fixing means through the adapter means and is put at the left front or right front side of the user's eyes with its one end away from the user's eyes inclining to the centerline. The shield is made of transparent color material, which not only shields the intense dazzle emitting obliquely from head-on approaching cars but also does not hamper the normal sight of the users. Said device further comprises a front shield. The present invention is simple in structure, convenient for use and very low in cost.
