Abstract
A combination includes eyewear, such as glasses, with a removable vapor barrier attachment. The eyewear includes a frame and lenses configured for protecting a user's eyes. The vapor barrier attachment is removably attached to the eyewear, and includes a base member removably attachable to the eyewear frame, and flap members extending from the base member. The flap members have a shape and length so as to extend longitudinally below the eyewear lenses. The flap members are attached to the eyewear along at least a portion of the length of the flap members and have a resilient sealing edge that conforms against the wearer's face to inhibit exhaled air from passing between the lenses and the wearer's face.
