Protective eyeglasses resistant to fogging while being worn by a wearer. The eyeglasses comprise a frame front which spans across the wearer's face and includes a forward side, an aft side, at least one middle portion extending over the wearer's eyes, and a pair of end piece portions near the wearer's temples. Attached to the middle portion of the frame front is at least one lens which is positioned over the wearer's eyes and defines front and back surfaces. Additionally, disposed within the frame front is at least one forwardly directed aperture which defines a ventilation channel for facilitating airflow through the frame front adjacent the lens. The ventilation channel defined by the aperture is sized and configured to facilitate the circulation of air over the back surface of the lens to resist the fogging thereof.

Protective eyeglasses (e.g., sunglasses) for use in high-speed outdoor sports activities, the lenses thereof being resistant to condensation, is achieved by air circulation created by venturi effects. The glasses comprise a frame front having middle portions over the wearer's eyes which support protective lenses, and having endpiece portions near the wearer's temples, the outboard edges of which attach temples which hold the glasses in place. A chamber is defined by the volume between the lenses and the wearer's face, and gaps are defined by the distance between the middle portions of the frame front and the wearer's face. Apertures in each of the endpiece portions of the frame front define an entrance of a ventilation channel for air flow through the frame front, adjacent to the respective chamber. Venturi forces are created within the ventilation channels to facilitate circulation of air. Improved ventilation, and the reduction or elimination of fogging on the lenses, is accomplished by low-cost and lightweight glasses.
