戴隐形眼镜的十大风险 （夺标的日志）（夹竹桃转载）
将一小块薄薄的塑料片植入你的眼球，就这样，原本模糊的周围世界瞬间尽收眼底！隐形眼镜使患有近视和远视的人们获得了正常的视力。今天，我们许多人都有带隐形眼镜。由于隐形眼镜变得极其容易佩戴，致使我们在如何保护隐形眼镜方面略显松懈。
当我们错误地佩戴、疏于保护和清洗隐形眼镜时，我们的眼睛会变得更为脆弱而被感染。戴隐形眼镜的人们应该谨记以下十个可能会为自己的眼睛带来不必要风险的情况。
摘取隐形眼镜时 通常在做这一步时，你的眼球会遭受感染以及不感到不适，毕竟那是因为你将自己的手指放到了眼睛里。在接触隐形眼镜或是眼睛之前，你需要彻底地把手洗干净，修短指甲以避免隐形眼镜的破裂或划伤。千万不要用自来水或是唾液来清洗隐形眼镜——应该根据自己的隐形眼镜的类型从而选择合适的清洗方法，或询问私人护眼专家正确的方法。
当佩戴时间过长 对为什么许多眼科医生会给出隐形眼镜不宜戴太久这一建议，有这样一个给力的解释，那便是这样会隔绝眼镜与氧气的接触。如果戴着隐形眼镜过夜或佩戴超出眼睛护理专家开出的时间，得角膜炎的几率就会大大增加。这会灼伤你的角膜甚至导致失明。
服用药物时 当然，在滴眼药水时你可能会摘下隐形眼镜。然而，你知道一些特定类别的药物会对隐形眼镜产生巨大的影响吗？服用避孕药会使女性的雌性激素激增，她们的眼睛也会因此对隐形眼镜变得更为敏感，同时，眼泪分泌的减少也会使她们双眼变得更加干涩。这些抗组织胺类的药物在缓轻过敏的同时也会使你的眼睛变得干涩。特定类型的药物会引起眼睛发痒症状，并且使用普通的阿司匹林会让眼睛有不适感。一定要将你服用过的任何常规药物的情况告诉你的眼睛护理专家。
当溶液已成问题 隐形眼镜的溶液有几种用途：有的用来漂洗或使隐形眼镜保持洁净，免受感染；有的是让眼镜重新湿润或增加泪的分泌；有的则是兼具多重功能。每一种这些类型的溶液都含有防腐剂。这些防腐剂可能是过期的，或是会为眼睛带来不适感。不要使用过期溶液。当我们选用其他品牌或是类型的溶液时，隐患也可能随之而来。即使你对同一款溶液情有独钟，生产商也可能更换了溶液。所以，我们对贴有“新款、改进“字样的标签要格外留意。另外，旅行时不要把溶液装到小盒子或是放到钱包里一起携带，这样会增加溶液受染的几率。
当眼睛过于干涩 由于镜片覆盖住了眼球表面并隔绝了其与空气的接触，许多戴隐形眼镜的人不时会感到眼睛干涩。在如搭乘飞机、天气干燥、服用抗组织胺类药物、酗酒过后等特定情况下，眼睛就会变得更加干涩。此时不妨带上一个装有人工眼泪或是润眼液的瓶子，并确切做到时常眨眼以保持眼球湿润。
带妆 你的化妆包和梳妆台堆满了可能刺激眼球的东西。不要让眼睛浮肿，红眼或是眼睛受过感染的人使用你的睫毛膏或眼线笔。你要选择抗水而非防水或是具有使睫毛增长配方的睫毛膏；选择低变应原的润湿剂、护肤液及粉底霜，因为乳脂状的化妆品会沾满和弄脏隐形眼镜。时间的把控也很重要——如果你戴的是软性隐形眼镜，在化妆前就要植入隐形眼镜；选择硬性通气隐形眼镜的佩戴者则需在化妆后植入。对任何类型的隐形眼镜佩戴者来说，一样的是你必须在卸妆前卸下隐形眼镜。
理发时 理发室堆满了啫喱水等其它具有化学成分的物品。为了保护我们的眼睛，下次就不要戴着隐形眼镜去理发。在对着吹风筒时，要更频繁地眨眼。
外出时 空气中细微的刺激物如灰尘，花粉，霉菌，烟雾以及动物的毛屑都可以通过各种途径进入你的眼睛从而引起不适感。如果对这些敏感物做出眼泪分泌过多的反应，戴隐形眼镜时就会感到不舒服。在花粉飘扬的日子里或是当你知道你会遇到这些刺激物时，最好考虑换戴普通的眼镜。
在水中浸泡时 当然，戴着眼镜跳入游泳池并不好玩。然而，带着隐形眼镜在用氯消毒过后的泳池，或在不知名但人来人往的天然水域里游泳，这样会增加隐形眼镜遭受感染的几率。如果你能把握好这一点，就可以不戴隐形眼镜放心地去游泳，但在戴回隐形眼镜前要等上半个小时。
抽烟时 当点燃香烟时，吸烟的人都知道那会为他们的健康带来风险。然而，吸烟时，戴隐形眼镜的吸烟者在患眼角膜溃疡的几率要比不吸烟者大八倍之多。 
后记：译完本文，才发现原来戴隐形眼镜有那么多风险。本人也是近视眼一枚，但从不戴隐形眼镜，总感觉不舒服。各位亲爱的读者，以后戴隐形眼镜，要多加注意才是丫。
10 risks for contact lens wearers
A small disc of thin plastic is fitted to your eyeball and, just like that, the world's fuzzy edges sharpen into focus! Contact lenses bring normal vision to the nearsighted and farsighted masses. So many of us wear contacts nowadays, and they've become so supremely easy to wear that we may get a little lax about taking care of them.
When we fail to properly wear, care for, and clean our contact lenses, our eyes become more vulnerable to infection. Contact lens wearers, take note of these 10 moments when you might be putting your eyes at unnecessary risk.
When you handle your lenses: Naturally, this step invites infection and irritation - you are putting your finger in your eye, after all. Thoroughly wash your hands before touching your contact lenses or your eyes, and trim your fingernails short so you don't tear or scratch your lenses. Never use tap water or saliva to wash your lenses - stick to the contact lens solution appropriate to your lens type. Ask your eye care professional which solution is right for you.
When you wear your lenses too long: There's a good reason why many eye doctors advise against the use of extended-wear contacts. Contact lenses block oxygen to your eyes. If you wear them overnight or for longer than prescribed by your eye care professional, you boost your risk of corneal ulcers that can scar your cornea or even cause blindness.
When you take medications: You would, of course, remove your lenses before putting in any type of eye-drop medication. But did you know that certain types of medications can have an impact on your contacts? Taking the birth control pill boosts estrogen and can make a woman's eyes more sensitive to her contacts, as well as decreasing tear output and making her eyes drier. Antihistamines to ease an allergy might also dry out your eyes. Certain types of acne medication can cause an itchy sensation, and plain old aspirin can irritate the eyes. Be sure to tell your eye care professional about any medications you take on a regular basis.
When your solution becomes the problem: Contact lens solutions come in many varieties: some rinse, some clean, some disinfect, some rewet the eyes or boost tear production, and some multipurpose formulas do it all. Each of these types of products contains preservatives that can expire or become irritating to the eyes. Don't use the solution if it's past its expiration date. Trouble can arise when switching brands or types of solutions. Even if you stick to the same brand, the manufacturers may alter the solution, so watch for labels that say things like "new and improved." Also, never transfer solution into a smaller container for travel or to carry in your purse - this can increase the risk for contamination.
When your eyes get too dry: Since contacts cover the surface of the eye and restrict oxygen, many wearers experience dry eyes now and then. And the dryness can become even worse in certain situations such as on an airplane, in a dry climate, while taking antihistamines, or after drinking alcohol. Carry a bottle of artificial tears or rewetting drops, and be sure to blink often to keep eyes lubricated.
When you put on makeup: Your makeup bag and vanity table is filled with possible eye irritants. Never share eye makeup or apply shadows, mascara, or eyeliner to swollen, red, or infected eyes. Choose water-resistant mascara instead of waterproof or lash-extending formulas. Opt for water-based hypoallergenic moisturizers, lotions, and foundations since creamy products can smudge and film up your lenses. And timing matters, too - if you wear soft contacts, insert your lenses before you apply makeup. Wearers of rigid gas-permeable lenses should wait until after. For both types of lenses, remove your contacts prior to removing makeup.
When you visit the hairdresser: Salons swarm with airborne chemicals from hairsprays and other products. Either don't wear your contacts to your next appointment or shield your eyes. Blink more frequently if you're stuck beneath a hair drier.
When you go outside: Tiny airborne irritants like dust, pollen, mould, smoke, and pet dander can make their way into your eyes and stick to your contacts can irritate your eyes. Excessive tearing in reaction to allergens can make it uncomfortable to wear your contacts. Consider switching to your glasses on high pollen days or when you know you'll encounter irritants.
When you take a dip: Sure, it's no fun to dive into the pool in your glasses. But wearing your contacts into a chlorinated pool or who-knows-what-infested natural body of water puts your lenses at risk of contamination. If you can manage it, swim lens-free and wait about an hour before you put your contacts back in.
When you light up: Smokers know that they put their health at risk whenever they stoke up a cigarette. But smokers who wear contacts are at 8 times the risk of developing corneal ulcers than non-smoking lens wearers.
Consult an eye care professional if you experience symptoms such as hazy or blurred vision or eye pain, or if you detect signs of an eye infection including discharge, itching, burning, or sensitivity to light. At the first sign of infection, remove your contact lenses.
