Light from the sun travels in waves which are oscillating (vibrating) in the same parallel direction. When these waves are reflected, for example off of a wet road, a glass or metallic surface or a body of water, the waves are ‘scattered’. They are then oscillating in a multitude of different directions – causing the bright and uncomfortable visual effect known as glare.
Polarized lenses are not only tinted – they also incorporate a special filter that only allows light through that is oscillating in the same parallel direction, thus eliminating virtually all reflected glare.
Drivers, skiiers and watersports enthusiasts can all benefit from polarized lenses – and they are particularly popular with anglers.
