Abstract: Eyewear has a detachable, light-blocking shield including a vent which enables airflow for moisture management and wearer comfort. The eyewear's nosepad can include a nosepad vent, and a temple can include a fluid channel and temple vent for further facilitating airflow and moisture management. The vent of the shield can direct airflow into a region behind a lens of the eyewear and increase the volume of air flowing across an inner surface of the eyewear lens and through the fluid channel.

Abstract: An eyewear frame includes a plurality of ventilation apertures disposed in fluid communication with corresponding ones of a plurality of fluid channels. The plurality of ventilation apertures are dimensioned and configured to conduct fluid from an outer face of the ventilated eyewear frame to an inner face. The plurality of ventilation apertures are further dimensioned and configured to conduct fluid from at least one inlet to at least two outlets, the fluid thus interacting with a plurality of fluid channels simultaneously. The plurality of fluid channels are dimensioned and configured to conduct fluid there along, and at least partially in communication with a wearer of the ventilated eyewear frame, facilitating heat exchange with the wearer, fluid drainage, and a reduction in fogging of the lenses of the eyewear.
