A goggle having a gas permeable structure, comprising a frame, a lens and a belt, wherein a plurality of gas permeable portions are arranged on the inner ring surface of the frame, the lens is mounted in the frame and has a majority on the circumference of the ring a through hole respectively communicating with the gas permeable portion of the frame, the two ends of the band being respectively connected to opposite sides of the frame, and the air inside and outside the goggle can be circulated through the gas permeable portion of the frame and the through hole of the lens frame To dissipate the hot air accumulated between the lens and the user's face to avoid fogging. The volume of the frame of the goggles of the present invention does not need to increase the volume outwardly in order to form the gas permeable structure formed by the gas permeable portion and the through hole, so that the goggles having the gas permeable structure of the present invention have a compact volume and lightness. The weight is easy for the user to wear.一種具有透氣結構之護目鏡,其具有一鏡框、一鏡片與一束帶,該鏡框之內環面上間隔設有多數個透氣部,該鏡片裝設於該鏡框中且於環周緣設有多數個分別連通該鏡框之透氣部的貫孔,該束帶的兩端分別組接於該鏡框的兩相對側,護目鏡內部與外部的空氣可經由該鏡框之透氣部與該鏡片之貫孔流通,以排散蓄積在鏡片與使用者之臉部之間的熱氣,避免產生霧氣。本發明之護目鏡的鏡框的體積不需要為了形成該透氣部與貫孔所構成的透氣結構而需要向外增大體積,故可令本發明的具有透氣結構之護目鏡具有精簡的體積、輕盈的重量,以便於使用者配戴。
