The present invention relates to a goggle with displaceable transparent film, which comprises a goggle body, a transparent film, a linkage device. The goggle body has lens, and the lens has a front surface, two side view portions corresponding to the positions of humans two eyes, and a central portion corresponding to the position of humans nose. The length of transparent film is longer than the width of lens, and is transversally configured on the side view portions of the front surface and the central portion of the lens. The linkage device is configured on the goggle body and connected with the transparent film, and may drive the transparent film to displace relative to the lens. The central portion of the lens is further configured with a protrusion externally protruded from the front surface, and makes the top end of the protrusion abutting with the transparent film to reduce the contact frictional force. Thus, the present invention may provide effect of better safety, reliability and lower cost.本發明係一種具可位移透明膜之護目鏡,包括一護目鏡主體、一透明膜、一連動裝置,並該護目鏡主體具鏡片,並鏡片具前表面,且對應人體二眼位置具二側觀看部分,並對應人體鼻部位置具中央部分;又透明膜長度大於鏡片寬度,並橫向設於鏡片前表面二側觀看部分及中央部分位置;又連動裝置設於護目鏡主體上,並與透明膜接合,並操控連動裝置可帶動透明膜對應鏡片位移,又於鏡片中央部分設置外凸於前表面之凸體,並使凸體頂端可抵靠透明膜以減小接觸摩擦力;藉此本發明可具較佳安全性、可靠性、減低成本功效。10...主體1...鏡片11...前表面111...觀看部分112...中央部分12...凸體2...透明膜3...連動裝置31...捲筒311...外殼32...捲筒321...外殼33...作動鈕
