Abstract
Eyewear 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.

Eyewear for use in sports and the like, comprising:
- a frame shaped to fit a wearer's face having an inner surface, an outer surface, a lens mounting surface for mounting a lens means for protecting a wearer's eyes, at least one lens mounted on said lens mounting surface, a nose bridge for supporting said frame on said wearer's face, and, a surface on each side of the frame for attaching a means for supporting the frame on the wearer's head;
- a ventilation liner mounted to the inner surface of said frame, said ventilation liner having an aperture of substantially the same size and shape as the lens mounting surface of the frame for providing a first deadspace between said lens and a first of said wearer's eyes and a second deadspace between said lens and a second of said wearer's eyes, said ventilation liner further having a front surface closely engaging the inner surface of said frame, said front surface including a plurality of filtered upper ventilation grooves for directing a flow of air through said first and second deadspace, said ventilation liner further including a channel connecting said first and said second deadspace for allowing air to flow between said first and said second deadspace, said ventilation liner further including filtered lower ventilation grooves for allowing air to flow through said first and said second deadspace, said ventilation liner further including a cushion mounted across a rear surface of said ventilation liner for engaging a wearer's skin around the wearer's eyes.
Eyewear for use in sports activities, comprising:
- a frame shaped to fit a wearer's face, said frame having an inner surface, an outer surface, a pair of orbital openings for surrounding the eyes of a wearer, a nose bridge connecting said pair of orbital openings, said nose bridge including a ventilation opening, a lens mounting surface mounting a lens over each orbital opening, and a surface on each side of the frame for attaching a means for supporting the frame on the wearer's head;
- and a ventilation liner including a channel mounted to divert air flowing through said ventilation opening to the space located between each lens and said wearer's face.
