There are plenty of glasses out there that may claim to be helpful when driving in the dark, but sometimes these claims are false. Glasses that are polarized or darkened may seem like a good idea to negate the effects of glare from the street lights and other motorists, but these can actually be detrimental to overall visibility.
There are a variety of glasses that have been specifically designed for driving at night, but make sure to see an optician beforehand, as they'll help you find a pair that's the perfect fit.
