A goggle (4) resistant to fogging is provided. The goggle consists of a water wicking and thermal transfer face gasket (1) combined with heat transfer inlets and outlets (41, 59) optimized for heat transfer to air flow through the goggle. With low airflow resistance in the vertically oriented inlets and outlets, the goggle ventilates by natural convection removing moisture and keeping the goggle from fogging. Simultaneously, the present goggle results in greater comfort for the user.

Cette invention concerne des lunettes (4) qui résistent à la formation de buée. Ces lunettes se composent d'un joint de visage d'absorption d'eau et de transfert thermique (1) combiné à des orifices d'admission et des orifices d'évacuation de transfert thermique (41, 59) optimisés pour un transfert de chaleur dans l'écoulement d'air dans les lunettes. On observe une faible résistance à l'écoulement d'air dans les orifices d'admission et les orifices d'évacuation orientés verticalement, ce qui permet aux lunettes d'être ventilées par convection naturelle, ce qui a pour effet d'évacuer l'humidité et d'empêcher les lunettes de s'embuer. Dans le même temps, les lunettes de cette invention procurent à l'utilisateur un plus grand confort d'utilisation.
