Um, no @JP Wilcox. She is 100% right and apparently has a better Internet connection than you do (seriously - thank Google's algorithmic search nonsense for that one). 

The kinds of streetlights (cheap Chinese) that are typically installed (I don't know what Eugene bought) have very poor "throw", which results in poor beam control/pattern and the complaints of light spilling out the sides that you see from most/many urbanites - with decent throw (A well designed LED streetlight) you don't get the spillage and have no need for "blinders". 

Most flashlights (multi-LED packages) also have poor throw, by the way.
