The short answers is a resounding NO.  This conclusion comes from a study at Harvard”s Mass. Eye and Ear Infirmary.


Ophthalmology researchers there tested 22 normally sighted drivers with and without yellow lenses for their ability to detect a dark-shirted pedestrian at night.  The yellow lenses did not improve the drivers response time to the pedestrian walking along in the presence or  absence of headlight glare.


So you night drivers can save the 15 to 30 bucks you were planning to spend on the glasses.  Without the crutch of a light filter, we all must rely on good old fashioned caution when driving at night.
