If you use a ski helmet with visor you do not need separate ski goggles. The visor is part of the helmet, so the helmet is helmet and goggles in one. For eyeglass wearers, a visor is certainly also a nice solution because of the extra space between your goggles and the visor. If you use a separate goggle or sunglasses, choose a helmet without visor. For off-piste use, there are special freeride helmets.
