【看英文中国邮报学英文】武汉肺炎疫情延烧，民众戴口罩保护，然而，戴口罩时眼镜片
容易起雾怎么办？
Wearing glasses is already quite cumbersome, and if things couldn’t get any
worse, your glasses may start to fog up and make seeing more challenging when
wearing a face mask.
英国贝德福德医院（Bedford Hospital）医师Sheraz Shafi Malik和英国之心（HEFT）医
师Shahbaz Shafi Malik在《英国皇家外科医学院年报》（Ann R Coll Surg Engl.）刊登
的文章指出，用肥皂水改变水滴张力，可解决镜片起雾问题。
In an article published on “Annals of The Royal College of Surgeons of
England,” however, two doctors, Sheraz Shafi Malik and Shahbaz Shafi Malik,
from Bedford Hospital and HEFT respectively, unveiled that soapy water could
solve the problem of glasses fogging up.
文内提到，戴上口罩前，先用肥皂水清洗镜片，将残留在镜片上多余水分甩干，接着将镜
片自然风干，或是用卫生纸轻擦镜面。之后当戴着口罩时，眼镜也不再起雾。
Before wearing your face mask, wash your spectacles with soapy water and
shake off the excess water. Then, let the glasses air dry or wipe them with
soft tissues. Your glasses shouldn’t be fogging up anymore, according to the
article.
至于为什么戴口罩时眼镜容易起雾，两位医师解释道，戴口罩呼气时会从口罩上方引到眼
镜，而呼气中水分热度较高，碰到较冷的镜片时会凝结成小水滴，因表面张力凝聚在一起
，而导致起雾的现象。
Why? The doctors said that a face mask directs much of the exhaled air
upwards where it gets into contact with the lenses. Condensation occurs on
glass lenses when water vapor — from your breath — gets into contact with
on a cold surface, forming a film you see as fog.
医师写道，肥皂水能够破坏水分子的表面张力，让水平均扩散，眼镜就不会起雾了。
According to the article, soapy water reduces the surface tension so water
would spread out evenly. As a result, your eyeglasses shouldn’t be fogging
up when wearing a face mask.
