捷优英语新闻提示：法国推出全新防雾镜片 帮助眼镜保持清晰。Keeping up appearances: The spectacles that don't get steamed up.

 

Whether slaving over a hot stove or simply stepping outside on a cold day, those who wear spectacles have long experienced the frustration of fogged-up lenses.

无论是在热气腾腾的炉灶前忙碌，还是仅仅在寒冷的天气里走出屋门，戴眼镜的人都经历过镜片起雾的困扰。

 

 

But such steamy moments – which usually happen when lenses are colder or warmer than the air around them – could be wiped out with the invention of non-fogging glasses.

但是随着防雾眼镜的发明，这种水汽蒙蒙的时刻——通常是由于镜片本身比周围空气温度低或者高——将会彻底终结。

 

The lenses are coated on either side with a material that is extra-attractive to water. Their inventors say this means that when condensation gathers, it becomes an invisible film rather than fog, leaving the lenses clear.

镜片的两边都涂上了一种吸水能力特别强的材料。发明者说，这意味着当冷凝的水汽聚集在一起时，会形成一层不可见的薄膜，而不是雾气，镜片依然会很清晰。

 

The Optifog lenses were designed by Essilor, the French firm that created the world's first varifocals in 1959.

这款名为“Optifog”的防雾镜片是由法国依视路公司设计的，这家公司曾在1959年推出世界首款变焦距镜片。

 

It believes the new lenses, priced from around £200 depending on type and prescription, will be of most benefit to cooks, sports enthusiasts such as runners and cyclists, and medics who wear face masks.

基于它的特征和材料，这种新的镜片售价大约在200英镑左右，人们认为它将会非常有利于厨师、运动爱好者，比如爱跑步或是骑自行车的人，以及那些戴口罩工作的医务人员。

 

The lenses are available in single vision, varifocal and sun-lens forms. They need to be sprayed with a chemical solution every week to keep the fog-repellent surface working.

这种镜片有单光、变焦、太阳镜三种形式，使用时需要每周在镜面上喷洒一种化学溶剂，才能保持防雾表面持续有效。

 

The solution costs about £5 a bottle and around four will be needed for the two-year lifetime of the lenses, which have just gone on sale.

溶剂售价大约每瓶5英镑，镜片使用两年约需要四瓶，该溶剂已经开始在市面上销售。
