ABSTRACT:
A sport goggle structure includes a rim having an inner circumference along which a circumferential slot is formed to receive and hold therein a lens and a head strap having two ends respectively connected to connecting holes formed on two opposite lateral side edges of the rim. The circumferential slot of the rim has a minimum depth that is sufficient to receive a circumferential edge of the lens in order to minimize the size of the rim. The size-minimized rim has ventilation device and face contact device provided thereon. The face contact device is to provide a more comfortable and position-secured engagement with wearer's face. The ventilation device is to guide fresh air flow from outside goggles through a right-angled bend and directly toward an inner surface of the lens to provide the best defogging effect.
