We integrate optical lenses exclusively into the double lens systems of established, premium quality ski goggles. The double lens configuration almost completely precludes the fogging that most wearers of ski goggles experience. This is a major advantage over clip-in systems or normal spectacles worn beneath ski goggles. However some misting is possible in very damp or wet conditions, and where the foam of the ski goggles becomes wet after a fall. If, for example, you remove your goggles and place them on the helmet in the gondola, please wipe the helmet first so that the foam of the ski goggles does not absorb any dampness from the helmet. Wet foam can cause the lenses to mist.
