Abstract
Abstract A device for preventing the eyes from being dazzled by the lights of an oncoming vehicle comprises a spectacle-type frame which carries anti-dazzle lenses having parallel, non-transparent, light-intercepting layers which are inclined forwardly and downwardly. The angular position of the lenses can be adjusted about a horizontal axis to provide the required anti-dazzle effect.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
169 words
A device for preventing the eyes of a user from being dazzled by the lights of an oncoming vehicle, said device comprising: a spectacle-type frame; lens support means carried by the frame; anti-dazzle lenses carried by the support means and having a transparent material and a plurality of substantially horizontal, parallel non-transparent, dull, light-intercepting strips embedded within said transparent material intermediate adjacent layers of said transparent lens material, each of said strips being inclined forwardly and downwardly; interlocking means detachably mounting the support means for selective pivotal movement relative to said frame about a substantially horizontal axis to permit the angular position of said lenses to be adjusted and locked in a plurality of incrementally angularly spaced positions relative to the normal position of the head in direct line with the eyes of the user to provide the required anti-dazzle effect, and the spacing of the strips being such as to cause said strips to intercept oncoming dazzling beams without a substantial change in the position of the head.
Claim 2
Independent Claim
169 words
A device for preventing the eyes of a user from being dazzled by the lights of an oncoming vehicle, said device comprising: a spectacle-type frame; lens support means carried by the frame; anti-dazzle lenses carried by the support means and having a transparent material and a plurality of substantially horizontal, parallel non-transparent, dull, light-intercepting strips embedded within said transparent material intermediate adjacent layers of said transparent lens material, each of said strips being inclined forwardly and downwardly; interlocking means detachably mounting the support means for selective pivotal movement relative to said frame about a substantially horizontal axis to permit the angular position of said lenses to be adjusted and locked in a plurality of incrementally angularly spaced positions relative to the normal position of the head in direct line with the eyes of the user to provide the required anti-dazzle effect, and the spacing of the strips being such as to cause said strips to intercept oncoming dazzling beams without a substantial change in the position of the head.
Claim 3
Dependent Claim
37 words
A device according to claim 1, wherein said interlocking means detachably mounts the support means on the frame and includes cooperatively serrated interlocking members for retaining the support means at a selected angular position on the frame.
