International ClassG02C 011/08AbstractEyewear is disclosed for use in sports and the like which captures airflow impinging on the front of the eyewear, filters it through baffling or a particulate filter to prevent the ingress of particulate matter, and then directs it through the dead space between the lenses and the wearer's eyes. The eyewear includes a frame shaped to fit a wearer's face including a front-facing ventilation opening, one or two lenses mounted in the frame, and a ventilation liner which includes filtered upper ventilation grooves extending through the top and bottom surface of the eyewear to allow air to flow through the dead space behind the lens. A cushion can be attached to the rear surface of the ventilation liner for cushioning the eyewear against the user's face. | |
