Here's an interesting set of accessory head light lenses. Looks like they would throw the light down in front of you to avoid glare for the oncomming traffic.
It’s interesting that Jay’s lenses are marked with a patent date
of December 8th 1914, which did not include the “eye lids”.
They show up on a later patent issued June 8th 1920.

Jay; I have a set in my truck, and I'm sure the green eyebrow is so we don't blind low flying aircraft.

I have a green eye brow set on my 26 green touring car. Since I installed them not one person has complained about me blinding them at night. A great safety accessory, plus they look cool
