HOW DOES POLARISATION WORK
With normal sunglasses light travels through the lenses in both horizontal and vertical directions. By incorporating a chemical filter during the manufacturing process of polarised lenses, the horizontal light, which is the principle reason for the glare, is nullified.
This allows only vertical light rays to pass through the lenses. By eliminating horizontal light, this dramatically reduces powerful rays distorting vision which allows the fly fisher to effectively look through the water surface. This is a massive advantage in visually identifying where fish are located.
