The utility model relates to an improved structure of goggles, which is made of a single transparent plate body. The plate body is provided with a concave arc edge in the center of the bottom edge, and a inserting piece is arranged on both sides of the concave arc edge, so that when the mask body is worn on the face, the inserting piece is inserted into the inner side of the mask body and between the cheeks at the two oblique upper corners of the mask body, and the concave arc edge is clamped or attached to the nose beam of the mask To form a vertical fixation effect.At least one supporting piece can also be provided at the bottom edge, which can be inserted into the inner side of the mask and clamped along the outer side of the mask to achieve a stable vertical position. Therefore, the protective goggles have the advantages of simple structure and low manufacturing cost, and can be discarded or cleaned and reused after one-time use, which can achieve the purpose of energy conservation and carbon reduction, and also greatly save medical expenses Cost.一種護目鏡改良構造，由單一透明片板體製成，該板體於底緣中央設有一內凹弧緣，於內凹弧緣兩外側各設有一支插合片，藉此當口罩本體配戴於臉部時，利用該插合片於口罩兩斜上角位置插合於口罩本體內側暨臉頰之間，同時內凹弧緣卡合或貼合於口罩鼻樑部位置，形成一垂立固定效果。亦可於底緣再設有至少一支抵靠片，利用插合片於口罩內側插入，及抵靠片循口罩外側的夾合而達到穩固的垂立，因此構造防護用護目鏡的構造簡單、製造成本低廉，可作為一次性使用過後即拋棄或清洗擦乾重新使用，能達成節能減碳目的，亦可大大節省醫療開銷成本。
