The Arfa sunglass / goggle fitted with polarised lenses is produced in our Australian factory. The frame is injection moulded from TR90, a hybrid nylon. While the Arfa was originally developed for use by surfers, it has a multitude of end uses (check out the applications on the top of this page). The Arfa is supplied with three sizes of flexible, interchangable nose bridges and two sets of gaskets - one set breathes and the other seals. The polarised lenses work best for use out of the water, boating or skiing. We do not recommend using polarised lenses when surfing or jetsking over waves, as the polarisation will affect take off, seeing through the wave instead of the top.
