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.
CHOICE OF LENS COLOUR
Copper/Green coloured lenses are a great optic solution for a range of light conditions. These lenses are very effective in medium to strong light and are a firm favourite with river and stillwater fly fishers as they enhance distinct contrast without noticeable colour distortion.
Grey/Blue lenses are excellent at maintaining true colour definition through the polarising filter. These lenses are very effective in bright sunlight conditions and also prevent the wearer suffering eye strain and fatigue in intense reflective light conditions on flats, rivers and lakes.Yellow:
Yellow lenses are highly effective at increasing contrast as well as depth perception. Excellent for low light conditions at dawn and dusk and also during dark, overcast fishing days. Very good general purpose lens colour for a cross-section of lighting conditions.
Copper coloured lenses are a great all round solution for a range of light conditions. Like the Copper/Green lenses, they are highly effective in medium to strong light conditions. A firm favourite with river and stillwater fly fishers as they enhance contrast without noticeable colour distortion.
