New Lens for Rear Auto Window Enlarges Backward View
A MOTORIST can ordinarily get a good view of only a small portion of the road behind him, and is consequently sometimes at a loss to know everything that is going on. An English manufacturer, however, has come to the rescue and put on the market a magnifying glass, which is a large diameter double convex lens of fairly low power, that is fitted to the center of the rear window of a car.
With this lens attached the motorist is enabled to get a far more comprehensive view of the road, as shown in the drawing at the left. It is also claimed by the makers that the lens cuts out the blinding glare of the headlights of following cars reflected in the windshield. The lens is easily installed.
