"Using “night-driving” glasses.
Some marketers offer specially tinted glasses
(usually yellow) that supposedly block the
wavelengths of light responsible for most
troublesome glare. Unfortunately, no matter
what their tint, these glasses also reduce the
amount of light that reaches your eyes, and
you need light to see. While these glasses
may reduce glare, they also reduce your night
vision overall—hardly a safe bargain."


any info appreciated
