[新聞] 清潔眼鏡的最佳方式

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.

行業組織VisionCouncil提供的數據顯示，接近50%的美國人佩戴用於矯正視力的眼鏡。他們中的大多數人在眼鏡護理過程中都犯過一個最嚴重的錯誤：對著鏡片哈一口氣，然後用襯衫袖子把鏡片上的霧擦掉。這真的會對鏡片造成損害嗎？美國驗光學會主席、內布拉斯加州奧馬哈市的驗光師蓋斯特(Teri Geist)對此進行了實驗。

Simple Solution
簡單方法
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.

儘管市場上有無數產品聲稱可以擦掉眼鏡鏡片上的污痕，但美國驗光學會(American Optometric Association)推薦的是最基本的選擇：廚房洗潔精。美國驗光學會主席蓋斯特(Teri Geist)稱，清潔眼鏡的最佳方式是將其在溫水下沖洗，在指尖滴一小滴洗潔精，在鏡片上打出泡沫，然後用溫水洗淨，並用乾淨柔軟的棉布擦乾。

‘Everyone uses their shirt cloth─worst thing!’ she says. ‘Your shirttail almost certainly carries dust, and that has the potential of scratching your lens.’

她說：“很多人都用他們的襯衫下擺擦眼鏡──這是最糟糕的做法！你的襯衣下擺幾乎肯定沾有塵土，這可能會刮壞鏡片。”

Glass vs. Plastic
玻璃鏡片與樹脂鏡片

Of the 69.1 million Americans who bought prescription spectacles last year, most purchased plastic lenses; glass has gone out of fashion as safety concerns have arisen. Unlike that hard surface, plastic is soft and can scratch easily.

去年，6,910萬美國人購買了處方眼鏡，其中多數都是樹脂鏡片；由於對安全的擔憂上升，玻璃鏡片已經過時。與玻璃鏡片堅硬的表面不同，樹脂鏡片柔軟而且容易被刮壞。

Once lenses are scraped up, ‘there is no way to buff that scratch out,’ says Dr. Geist. Attempting to clean glasses when dry only exacerbates the problem, since a wet surface is slicker than a dry one. ‘People breathe on their glasses then grab a Kleenex or paper towel or napkin because they’re convenient, but the rough fibers that they’re comprised of might leave debris behind,’ Dr. Geist says. She adds that special microfiber cloths are good for dry touch-ups during the day, but aren’t a stand-in for a thorough, soapy cleaning. Neither is your breath.

蓋斯特博士說，一旦鏡片有了刮痕，“就沒有辦法除去”。在鏡片乾燥時擦眼鏡只會加劇問題，因為濕潤的表面會比干燥的表面光滑一些。蓋斯特博士說：“人們在鏡片上哈氣，然後順手抓起一張餐巾紙去擦眼鏡，但構成餐巾紙的粗糙纖維可能會在鏡片上留下碎屑。”她補充說，特殊的超細纖維布適於乾擦鏡片，但它不能替代徹底的皂液清潔方法。你的哈氣也不行。

Reflecting on the Problem

塗層問題

Lenses typically have some form of protective coating and should never come into contact with ammonia, bleach, vinegar or window cleaner. ‘Those chemicals can break down the coating or just strip them,’ says Dr. Geist. ‘You know those bubbles you sometimes see on your lens? Those are caused by ‘cleansing’ solutions.’ Avoid the problem by requesting anti-glare and UV coatings that are embedded within the lens, which can cost about $100 more than regular-coated lenses.

鏡片通常有某種形式的防護塗層，因此不應接觸氨、漂白劑、醋和窗戶清潔劑。蓋斯特博士說：“這些化學物質會破壞或者洗掉塗層。你知道有時在鏡片上看到的泡泡印是怎麼回事嗎？那就是用’清潔劑’導致的。”要求在鏡片中加入防眩光和紫外線塗層可以避免這個問題，這種鏡片的價格比普通塗層鏡片高出約100美元。

Clean Lines

清潔產品

Natural oils from your hands, eyelashes and face can lead to a lot of buildup each day, reducing lenses’ effectiveness. Leaving spectacles on a sink or vanity, where hair spray and perfume can fly through the air, adds to the residue. The AOA recommends washing glasses every morning, paying special attention to the frames and earpieces, where hair product and makeup tend to rub off. Whatever you do, don’t use the most handy form of water to clean your lenses. ‘Some people use spit, but don’t,’ urges Dr. Geist. Though dirty glasses won’t cause an eye infection, saliva ‘is not the best hygiene method, and it just won’t work very well,’ she says. Soap, warm water and a dry cloth are all you need, once a day, to keep glasses optimally clean and functional. ‘I have had patients who say they can’t see well, but it turns out it is just the scratches,’ says Dr. Geist.

手、睫毛和麵部每天產生的天然油脂可能大量堆積在鏡片上，降低鏡片的透光性。將眼鏡放在水池或衛生間檯面等可能殘留髮膠和香水飛沫的地方會增加殘留物。美國驗光學會建議每天早上清洗眼鏡，尤其應該注意鏡框和鏡腳等容易擦到護髮品和化妝品的地方。無論你做什麼，都不要用最現成的“水”來清潔鏡片。蓋斯特博士說：“有些人用唾液，可千萬別這麼做。”儘管臟鏡片不會導致眼部感染，但唾液“不是最衛生的方法，而且它的效果也不好”。你只需要每天用皂液、溫水和一塊乾布，即可保持眼鏡清潔好用。蓋斯特博士說：“我的患者中，有些人說他們看不清，結果只是鏡片上有划痕。”
