Abstract: Eyewear is disclosed for use in sports and the like which allows the wearer to attach a removable sealing member to prevent the ingress of particulate matter when active sports are engaged in which require both ventilation and sealing to keep dust, dirt and the like out of the eyes. The sealing member is removable so that when the user is engaged in more casual activities, the frame may be worn like ordinary glasses or sunglasses without the sealing member. The eyewear includes a frame shaped to fit a wearer's face, one or two lenses mounted in the frame, and a temple bracket mounted on each side of the frame. A ventilation opening can be provided on the front surface of the frame to provide an airstream which is channeled by the removable insert to provide a filtered airflow across each lens.
