Most of fatal road accidents occur at night and at dawn presumably because of the problem of poor visibility caused by blinding glare of the oncoming headlights, powerful road lights. The ultimate night driving solution is now available in the form of night driving filter.
The Central Scientific Instruments Organization, Chandigarh, has come up with an antiglare optical device for automobiles most useful during night driving. It is mounted in front of the driver on the automobile’s windshield.
The frequent blinding glare not only makes the driving difficult but also impairs the vision. The device has the provision to be flipped on the windshield at the eye level when in use and can be latched on to the vehicles ceiling when not required. The device comprises of a gradient density absorbing film deposited upon glass/plastic substrate by vacuum coating and also anti-reflection coating on both surfaces of the substrate.
The filter used has a special type of graded coating and it is the uniqueness of the filter. The device is used during night driving to protect eyes from the blinding glare (excessive visible radiation and UV radiations) produced by the headlight of approaching vehicles.
This filter is the first-of-its kind glare reducing technique. This filter cuts down light intensity almost uniformly over the visible range, in the areas in front of the drivers eyes, where there is maximum occurrence of glare. At the same time, it maintains high transmission at both ends of the filter to see the road signs and other passing vehicles thus enhancing road safety manifolds.
Technology ready for transfer. Glare/excessive light of the coming vehicles using high a low beam is reduced to comfortable viewing i.e. high beam reduce to 30% and low beam reduce to 40%.
