摘要:
A protective lens to be attached to a face mask or used without a face mask as goggles or glasses to cover the eyes of, for example, one playing the game of paintball. The protective lens has a body to be worn over the eyes of a wearer and a thermal backing that is spaced from the lens body to lie closer to the wearers eyes than the lens body. A volume of air or similar gas is trapped within an air space between the lens body and the thermal backing to prevent the transfer of heat from one to the other. A seal surrounds the air space so that the air trapped therein is isolated from the atmosphere. A rib projecting from the lens body surrounds and lies outside the seal to prevent the seal from becoming saturated with liquid, paint, and the like which might be encountered during play. The trapped air within the air space prevents the protective lens from fogging and obstructing the wearers view as a consequence of the lens body and the thermal backing having different temperatures.
