Abstract
Goggles include an inner lens plate, an intermediate lens plate and an outer lens plate. A space between the inner and intermediate lens plates and a space between the intermediate and outer lens plates form heat-insulating layers. The intermediate lens plate has a through hole and at least one of the inner and outer lens plates has a vent hole. The vent hole is covered with a moisture blocking member which prevents moisture from passing and allows air to pass.
