It is the lenses that make a difference between polarized goggles and non-polarized goggles . Polarized lenses are designed to reduce the glare from surfaces like water, snow, and glass and increasing depth perception. When light falls on a flat and smooth medium, the reflected light is directed in the horizontal planes (polarized), rather than dispersing or scattering in all directions. They have been popular for years with boaters,fisherman and help the participant in these activities to see more clearly, allowing for the avoidance of potential hazards. So the polarize lenses are more expensive than the regular one .
