Another Early Anti-Glare Headlight Lens

The very modern problem of headlight glare has roots going back to the earliest days of automobile travel. Companies such as Osgood and Liberty developed some interesting lenses in an attempt to alleviate the problem, and Warner-Patterson also took a stab at it with this unique lens that looks like it is covered with bubbles:

The company called it a Warner-Lenz, and it is marked with a 1912 patent date. The following description of the lens appeared in a 1917 issue of the Automobile Trade Journal:

On the front of the Warner-Lenz are rows of small lenses and on the back are similar rows which overlap so that all the light coming from the lamp is diffused in a spray which covers almost 180 deg. with a gradual reduction of intensity toward the sides. The light is thrown all over the road and on both sides so that everything in front of the car may be clearly seen for from 300 to 500 ft. in front of the car.

The New York Secretary of State officially declared the Warner-Lenz to be legal, according to this 1918 advertisement. The square in the middle of the page also contains the names of makes that were using the lens as standard equipment with Packard and Stutz topping the list.

The ad also claims there were more than a million pairs of these lenses in use at this time. Whether that statement is truth or hyperbole, there do not seem to be too many survivors. There are currently only a handful of listings on eBay with prices ranging from $59 to $299.
