眼睛對一個人的作用有多大？它帶我們馳騁世界，助我們與帥哥美女眉目傳情，但直到它出現(xiàn)問題我們才意識到它的重要性。事實上，眼睛比你想象的更加敏感：不論是化妝品、空調(diào)，還是日常生活中的其它物品，都會對眼睛造成影響。下面就教你幾招護(hù)眼常識，讓你擁有洞察萬象的雙眸。

Q1、My eyes are always itchy this time of year

每年的這個時候我的眼睛就會發(fā)癢

Seasonal allergies can make your eyes itch like crazy, thanks to the histamine they (and other body parts) produce in response to pollen and other irritants.

        季節(jié)性過敏會讓眼睛癢得要命，好在人體內(nèi)的組胺（和其他部位）能幫助你抵擋花粉和其它過敏原的侵襲。

改善方法

Staying indoors with the windows shut is ideal, but we know you can't be a total recluse. So use over-the-counter allergy eyedrops such as Naphcon-A, or ask your doc to prescribe a more potent one such as Pataday, says Anne Sumers, MD, a clinical correspondent for the American Academy of Ophthalmology. And shower before bed so pollen's not lingering on your face and in your hair all night long.

        應(yīng)對這種過敏癥最理想的辦法就是待在門窗緊閉的室內(nèi)，但你不可能一直這么宅著。因此，美國醫(yī)學(xué)博士、眼科學(xué)會臨床發(fā)言人安妮·蘇梅爾斯（Anne Sumers）建議使用治療過敏癥的非處方滴眼液，如那素達(dá)滴眼液（Naphcon-A），或者找醫(yī)生開些特效藥，比如奧洛他定眼藥水（Pataday）。另外，睡前洗澡也十分必要，這會防止花粉等過敏原整夜殘留在你的臉部或頭發(fā)上。

Q2、Why are my lids pink and puffy?

為什么我的眼皮又紅又腫？

If one or both of your eyelids are inflamed, itchy, and red, you may have blepharitis, which occurs when bacteria or excessive oil from your eyes coats the lid near the eyelash line. It can also be caused by allergies. "Blepharitis, which is not contagious and usually doesn't require antibiotics, often gets mistaken for pink eye, which is usually caused by a virus and is highly infectious," Dr. Sumers says. Check in with an eye doctor to figure out which one you've got. A pink eyelid can also mean you have a sty, a bacterial infection on your lid that takes the form of a painful, pus-filled pimple.

        如果眼皮出現(xiàn)紅腫發(fā)癢的癥狀，那你很可能患上了瞼緣炎。這種炎癥通常是由眼部細(xì)菌或分泌的油脂感染睫毛線附近的眼皮而引起的，但也可能是由過敏所致。蘇梅爾斯博士說：“瞼緣炎并不傳染，也不需要使用抗生素進(jìn)行治療。它經(jīng)常被人們誤認(rèn)為是結(jié)膜炎，這是一種由病毒引起的高傳染性疾病?！彼援?dāng)眼睛出現(xiàn)類似癥狀時，去找位眼科醫(yī)生確診一下吧。結(jié)膜炎（又稱紅眼?。┖脱鄄€炎一樣，都是由細(xì)菌感染引發(fā)，并伴有麥粒腫，帶給你腫痛感，甚至還會化膿。

改善方法

Prevent and treat both styes and blepharitis by keeping the eye clean. Soak a washcloth with warm water, wring it out, and place it over your closed eye for a minute or two. Do this two or three times a day. "Clean all your eye makeup off every night," Dr. Sumers adds, "and never wear eyeliner inside your lash line." And no matter how tempted you are, don't pop a sty, or you could spread the infection.

        通過保持眼部衛(wèi)生來預(yù)防和治療眼瞼炎和結(jié)膜炎。將毛巾浸入溫水中，取出擰干，熱敷雙眼一到兩分鐘，并每天重復(fù)兩到三次。蘇梅爾斯博士補(bǔ)充說：“每晚睡前要將眼妝卸干凈，而且一定不要畫內(nèi)眼線?！绷硗?，無論如何都不能自己動手刺破膿腫，這樣很容易導(dǎo)致感染擴(kuò)散。

Q3、My eyes are burning!

我的雙眼灼痛！

If you feel a gritty, scratchy, or even stabbing pain in your eyes, you may be one of the 10 million Americans suffering from dry eye syndrome. Blame modern life: Air-conditioning and central heating can leave eyes parched, says Stephanie Marioneaux, MD, an ophthalmologist in Chesapeake, Virginia. Plus, studies have shown that when we stare at a screen, we don't blink as often, so our eyes lose their natural lubrication. If you wear contact lenses, you're more prone; same goes if you smoke or take medications such as antihistamines or decongestants.

        如果你的眼睛有異物感、摩擦感，甚至是刺痛感，那你很可能患上了干眼癥，這種眼部疾病在美國的患病率為千分之一。美國弗吉尼亞州 切薩皮克市眼科博士斯蒂芬妮（Stephanie Marioneaux）表示，干眼癥的病因歸咎于現(xiàn)代化生活：空調(diào)和暖氣的使用會讓眼睛變得干燥。此外，研究表明，當(dāng)我們長時間盯著屏幕時，眨眼的次數(shù)較平時變少，眼睛也因此失去了原有的潤滑。如果你佩戴隱形眼鏡、吸煙或服用具有抗組胺或緩解充血功效的藥物時，患干眼癥的幾率更大。

改善方法

Try artificial tears. "Gels that are labeled 'for severe dry eye,' such as Systane, are thicker and last longer, but they can feel gummy and blur vision," Dr. Sumers says. "Drops that are labeled 'mild to moderate,' such as Refresh, are thinner and feel better, but won't last as long."

        試試人工淚液。蘇梅爾斯博士表示：“那種標(biāo)有‘適合嚴(yán)重干眼癥’的人工淚液，如視舒坦（Systane），它們的粘稠度較高，持續(xù)時間較長，但會讓眼睛感覺過于黏稠而視力模糊。最好選用那種‘濃度較低但很溫和’的人工淚液，如 Refresh。雖然它們的效果持續(xù)時間不長，但粘稠度較低，會讓眼睛舒服些?！?/span>

If drops don't do the trick, your doctor can prescribe a topical medication or fit you with punctal plugs (they're inserted into your eye to keep tears from draining too quickly). Use a vaporizer or humidifier to keep indoor air moist, too. Surprisingly, eating fish high in omega-3 fatty acids—such as salmon, sardines, and tuna—may reduce your risk of dry eye, and taking flaxseed oil and omega-3 supplements may relieve symptoms, studies suggest. And every 10 minutes or so, look away from your computer or tablet screen and bat your lids like Scarlett O'Hara.

        如果人工淚液不奏效，可以請醫(yī)生為你進(jìn)行局部藥物治療，或者進(jìn)行淚道栓塞治療（植入淚道塞，防止眼淚較快流干）。此外，你也可以使用噴霧器或加濕器保持室內(nèi)空氣濕潤。令人吃驚的是，研究表明，食用富含歐米伽 3（omega-3）脂肪酸的魚類——如鮭魚、沙丁魚和金槍魚等——能預(yù)防干眼癥，食用亞麻籽油和補(bǔ)充歐米伽 3脂肪酸還能減輕干眼癥癥狀。此外，每隔十分鐘左右，把眼睛從電腦屏幕上移開，用手指輕拍眼皮也有效果。
