Oakley Prizm Lenses
Low light caused by cloud can prevent you from being able to see contours and undulations in the terrain. This makes the snow appear completely smooth, which can be very disorienting.
The white light reflected off snow is made up of an almost equal amount of all colours, but your eye is more sensitive to some than others.
The Prizm lens is designed to filter the light and emphasise the colours to which the eye is most sensitive, allowing you to detect greater levels of detail in the landscape, react faster and ultimately ride with confidence.
