吸菸vs.菸毒性弱視

 

弱視就是矯正視力低於0.8,”菸毒性弱視”這是吸菸對眼睛最常見的危害。吸菸導致弱視的原因,一是由於吸菸時人體吸入的氧氣被消耗,致使血中氧的含量下降,而眼視網膜對缺氧格外敏感,長期下去可造成視力損傷,讓視神經纖維、視網膜的黃斑區出現病變、視網膜乳頭黃斑區也會發生萎縮;二是菸草燃燒時產生的菸焦油會導致體內維生素B12的含量下降,而維生素B12是維持視神經正常功能所必需的營養物質。在這兩者共同的影響下,使得吸菸者視力下降而發生菸毒性弱視和菸毒性視神經萎縮,嚴重者可致失明。 眼球結構

菸毒性弱視的症狀
◎視力障礙:視物不清,戴眼鏡也難以矯正,隨著視力減退逐漸加重,到一定時期,連視力表上0.1也看不清楚。
◎視野改變:早期視野中間出現一團啞鈴形或圓形黑影,後期視野縮小,視物時四周模糊不清。
◎色覺導常:尤其是辨不清紅、綠顏色。
◎畏光:在強光下視物反而不清楚。菸草中毒性弱視病情發展比較緩慢,很容易被人們忽視,晚期嚴懲時可能造成失明。

菸毒性弱視的預防
◎堅決戒掉吸菸的壞習慣,遠離吸菸環境,這是防止菸草中毒性弱視發生和發展的關鍵。
◎少飲酒,更不能菸酒兼嗜。
◎經常食用富含維生素類及蛋白質類食物,如豆(黃豆芽、豆腐、腐乳、豆豉等)、肉類(特別是食劃動物的心、肝、腎)和魚類等。
