捷優英語新聞提示：法國推出全新防霧鏡片 幫助眼鏡保持清晰。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.

無論是在熱氣騰騰的爐灶前忙碌，還是僅僅在寒冷的天氣里走出屋門，戴眼鏡的人都經歷過鏡片起霧的困擾。

 

 

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.

但是隨著防霧眼鏡的發明，這種水汽蒙蒙的時刻——通常是由于鏡片本身比周圍空氣溫度低或者高——將會徹底終結。

 

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.

鏡片的兩邊都涂上了一種吸水能力特別強的材料。發明者說，這意味著當冷凝的水汽聚集在一起時，會形成一層不可見的薄膜，而不是霧氣，鏡片依然會很清晰。

 

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

這款名為“Optifog”的防霧鏡片是由法國依視路公司設計的，這家公司曾在1959年推出世界首款變焦距鏡片。

 

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，這種新的鏡片售價大約在200英鎊左右，人們認為它將會非常有利于廚師、運動愛好者，比如愛跑步或是騎自行車的人，以及那些戴口罩工作的醫務人員。

 

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.

這種鏡片有單光、變焦、太陽鏡三種形式，使用時需要每周在鏡面上噴灑一種化學溶劑，才能保持防霧表面持續有效。

 

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.

溶劑售價大約每瓶5英鎊，鏡片使用兩年約需要四瓶，該溶劑已經開始在市面上銷售。
