ANTI-GLARE LENS

BRISBANE CHEMIST’S INVENTION

The practice of dimming lights is now universally recognised as positively dangerous, hut no matter what can bo said to the contrary, glaring, dazzling headlights constitute just as serious a menace to the safety of the highways at night time. The latest English invention to combat the danger of blinding headlights is a ponderous mechanically operated “dipping” device, which is controlled from the driving sent. The device places all lamps oa hinges, ami no matter how neatly component parts may fit when new it seems that rattle will inevitably develop, and that in a very short space of time. All over the world attention is being devoted to solving the headlight glare problem, but so far no outstanding success lias been achieved. All invention of a Brisbane consulting chemist, Mr Holiib. lias, however, somewhat changed the outlook. Mr llolub has for some time been convinced that a lens could ho produced which would, by diffusing the headlamp, rol> it of its glare without taking from it its illuminating power,

and when lie at last compounded a chemical emulsion to use as a basis In his lens, and put it to the test, the success of the experiment surprised even himself, who was confident of success throughout. In his research ho was guided by the relative diffusivo powers of the colloids of different minerals, and he made the compound of a suitable chemical admixture. The lens itself comprises a layer of the emulsion placed between two ordinary glass discs, whose only function is to protect the layer of material which accomplishes really the remarkable results. In an article recently on Mr Ilolub’s invention, the “ Brisbane Courier’s” motoring editor states that with the lights of a car full on one can stare directly at the source of light, which, though strong, has no ill-effects, bcnated by the passage through the lens, cause tho harmful red rays are elimi-
