Anti-dazzle glasses for motorists - lenses are divided into one absorbent and one clear section

摘要

The lenses divided by a vertical line (2) into two principal parts, of which one part (3), to the left of the wearer, is strongly absorbent of light while the other part (1) is clear. With the extreme left side of the wearer's pupil coincident, in projection, with the vertical line (2), the wearer will see the road ahead clearly at night through the clear part (1). If he meets an oncoming vehicle, a light reflext movement of the head towards the right avoids dazzling. The device can be further improved by dividing the lens into four sections by the vertical line and an oblique line and providing three different absorption values; this protects the eyes in urban areas against street lighting effects.
