ABSTRACT:
The invention provides light-blocking air vents for eyewear. A frame for the eyewear has a brow web that extends approximately horizontally from a top portion of the frame. The brow web includes at least one ventilation aperture having a internal side that is substantially sloped with respect to a top surface of the brow web. One or more lenses are mounted to the frame. Air is allowed to pass through the aperture. However, by providing that the internal side of the aperture is substantially sloped, light is blocked from entering through the aperture. The brow web may include a plurality of ventilation apertures for each of two lenses mounted to the frame. The apertures for each lens are arranged substantially equally-spaced in a row. A lower web may also be provided that includes one or more ventilation apertures. Side lenses may also be provided along with apertures for ventilating the side lenses.
