ABSTRACT:
A night driving dazzle protection system uses anti-dazzle screening material transmitting less than 40% of incident light and arranged on screened portions of right and left eyeglass regions 30 and 20 in front of a driver's eyes. As viewed by the driver, the eyeglass region 20 in the view of the driver's left eye is screened between about 7:30 o'clock and about 9:00 o'clock, and the corresponding eyeglass region 30 in the view of the driver's right eye is unscreened between about 7:30 o'clock and about 9:00 o'clock. Preferably, right and left eyeglass regions 30 and 20 between about 3:00 o'clock and about 4:30 o'clock are screened for the driver's right eye and unscreened for the driver's left eye. Also, upper portions of each of the eyeglass regions are preferably screened from about 9:00 o'clock to about 3:00 o'clock.
