The SolarPro™ 2 Polarised eliminates glare and visual distortion magnified by flat surfaces such as water, the road and steel surfaces. Featuring a grey polarised lens which works well in a variety of conditions, offering absolute true colour recognition without distortion, by reducing the orientated light causing glare. Fine details and true colours are seen without strain and can be worn all day with minimum eye fatigue. HOW DOES THE POLARISED LENS WORK? When light bounces off a surface its waves tend to be strongest in a particular direction, usually horizontally, vertically or diagonally. Sunlight bouncing off a surface like a road, water or steel will reflect horizontally striking the viewers eyes intensely, causing glare. A polarised lens is laminated with tiny vertical stripes which only allow vertical light to enter the wearers eyes. Glare is eliminated because the horizontal light waves cannot bypass the vertical filter.
