Nearly 50% of Americans wear corrective glasses, according to the trade group Vision Council. And most of them are guilty of the biggest crime in lens care: Exhaling onto their lenses, then wiping the fog off with their shirt sleeves. But does this really damage your lenses? Teri Geist, an optometrist in Omaha, Neb., and chairwoman for the American Optometric Association, weighs in.
行业组织VisionCouncil提供的数据显示，接近50%的美国人佩戴用于矫正视力的眼镜。他们中的大多数人在眼镜护理过程中都犯过一个最严重的错误：对着镜片哈一口气，然后用衬衫袖子把镜片上的雾擦掉。这真的会对镜片造成损害吗？美国验光学会主席、内布拉斯加州奥马哈市的验光师盖斯特(Teri Geist)对此进行了实验。
Simple Solution
简单方法
Though there are countless products on the market claiming to wipe streaks away, the AOA recommends the most basic of options: kitchen-sink soap. The best way to clean your glasses, says Dr. Geist, is to run them under warm water and put a tiny drop of dishwashing detergent on the tip of your fingers to create a lather on the lens. Then rinse with warm water, and dry with a clean, soft cotton cloth.
尽管市场上有无数产品声称可以擦掉眼镜镜片上的污痕，但美国验光学会(American Optometric Association)推荐的是最基本的选择：厨房洗洁精。美国验光学会主席盖斯特(Teri Geist)称，清洁眼镜的方式是将其在温水下冲洗，在指尖滴一小滴洗洁精，在镜片上打出泡沫，然后用温水洗净，并用干净柔软的棉布擦干。
'Everyone uses their shirt cloth─worst thing!' she says. 'Your shirttail almost certainly carries dust, and that has the potential of scratching your lens.'
她说：“很多人都用他们的衬衫下摆擦眼镜──这是最糟糕的做法!你的衬衣下摆几乎肯定沾有尘土，这可能会刮坏镜片。”
