I originally purchased the lenses for my wife.  She found them obsructing her view.  I was able to share them with my mom and she was able to put them to use.  So far so good.  Car companies and owners are installing the HID lights to their vehicles and they can be difficult to deal with in your rear view or on coming traffic. Even people in the city are using. These lenses help reduce the glare, which is why I purchased them.
