Bertoni P180A, sunglasses polarized

While driving, water, snow, glass, other vehicles, etc. cause reflections. Like a mirror it strengthens the intensity causing it to be very annoying. Good eye protection against those reflections or glare is therefore very important for motorcyclists. Polarized lenses reduce these harmful rays strong. Daylight travels in three dimensions, while polarizing light moves in two directions namely horizontal and vertical. Vertical light gives the human eye important information, it allows us to see colors and contrasts. Horizontal light causes optical disturbance as glare, polarized lenses block the horizontal light. Polarizing lenses increase contrast and improve color perception therefore you can ride a lot relaxed and safer.
