This creation relates to a goggle ventilation structure, which is mainly provided with corresponding adjustment seats on both sides of the lens frame corresponding to the lens set hole, a long slot hole is opened on the adjustment seat, and upper and lower sides are provided on both sides of the lens frame. The upper and lower penetration holes correspond to the lower part, so that the lens corresponds to the lens group setting hole, and the two sides of the lens corresponding to the adjustment seat are convexly provided with a plug-in combination of a plug-in combination, and the plug-in portion corresponds to a long slotted hole to form a limited convex portion. The upper and lower ends of the positioning member are respectively provided with upper and lower through-holes corresponding to the upper and lower insertion holes, and the positioning member corresponding to the positioning latching portion of the lens is provided with a positioning convex portion that can be combined with each other. ； In this way, the lens can be adjusted to move outside the frame when needed, so that a gap is formed between the lens and the frame, and the gap formed between the lens and the frame can be used to allow air to circulate to achieve better ventilation. Efficacy, and in the overall implementation and use of more practical features.本創作係有關於一種護目鏡透氣結構，其主要係於鏡框對應鏡片組設孔之兩側設有相對應之調整座，於調整座開設有長槽孔，於鏡框兩側皆開設有上、下相對應上、下穿設孔，令鏡片對應鏡片組設孔設置，於鏡片兩側對應調整座凸設有插掣結合之插掣部，於插掣部對應長槽孔形成有限位凸部，令定位件上、下端對應上、下穿設孔分別凸設有穿設結合之上、下穿設桿，定位件對應鏡片之定位卡掣部凸設有能相卡掣結合之定位凸部；藉此，以能在需要時調整讓鏡片往鏡框外移動，使得於鏡片與鏡框之間形成有縫隙，即可利用鏡片與鏡框之間所形成的縫隙讓空氣流通，達到更佳的通風透氣功效，而在其整體施行使用上更增實用功效特性者。
