You might want to think twice before layering onyour eyeliner at your lower lash line. A new study inthe Eye and Contact Lens journal found that usingeyeliner on your inner lash line may put you at riskfor infection and vision trouble。

用眼線筆畫下眼線前你可能要三思而后行。《眼睛和隱形眼鏡》雜志的一個(gè)新的研究發(fā)現(xiàn)，使用眼線筆畫內(nèi)眼線可能會(huì)造成感染和視力問題。

The study was conducted by Dr. Alison Ng, a post-doctoral fellow in the School of Optometryand Vision Science in the Faculty of Science at Waterloo, who used video recordings to track themigration of eyeliner particles into the eye depending on the makeup application.Participants in the study applied a glitter liner to their outer lash line and then to theirwaterline."We noticed the makeup migration happened quicker and was greater when theeyeliner was put on the inner lid," says Ng。

這項(xiàng)研究由滑鐵盧科學(xué)院光學(xué)和視力學(xué)博士后艾莉森主導(dǎo)，她使用視頻跟蹤眼線膏在紋過眼線的眼睛中的移動(dòng)軌跡。實(shí)驗(yàn)人員在外眼線上使用閃光眼線筆，然后再畫到水線。

"我們注意到其中的成分在到達(dá)眼瞼時(shí)移動(dòng)突然加速，影響也在加強(qiáng)。"

When the liner was applied to the inner lash line,15-30 percent more particles entered the tearfilm—the thin protective coating on the eye—than when liner was applied outside the lash line.The problems with liner entering the tear film ranges from minor discomfort for those withdry or sensitive eyes to more serious infections and blurred vision."People who wear contactlenses are most likely to notice some problems," says Ng."If they have eyeliner stuck to theirlenses, increasing deposits might cause vision disruption as the lens becomes cloudier."

當(dāng)眼線膏被畫在內(nèi)眼線上時(shí)，進(jìn)入淚液膜——眼睛里薄薄的保護(hù)膜——的成分比畫在外眼線上時(shí)多出15-30%。眼線膏進(jìn)入淚液膜后可能會(huì)造成眼球干澀敏感，嚴(yán)重會(huì)造成感染和視力模糊。"戴隱形眼鏡的人更容易感覺到問題，"艾莉森說(shuō)，"如果有眼線膏附著在隱形眼鏡上，不斷增加的沉積物會(huì)導(dǎo)致視力云狀模糊。"

Not ready to give up inner liner? New York City-based makeup artist Lisa Aharon says there areways to get the look and minimize your risk for infection."When using eyeliner on yourwaterline, look for a cream pencil as opposed to a kohl," says Aharon."Kohl contains heavymetals like lead that could be harmful to the health of your eye." Aharon also recommendsavoiding glitter or metallic liners on the waterline, as the flecks are more likely to causeirritation。

還想繼續(xù)畫內(nèi)眼線嗎?紐約市化妝師麗莎·阿哈龍說(shuō)，還是有辦法減少感染風(fēng)險(xiǎn)的。"當(dāng)在你的水線上使用眼線筆時(shí)，找一個(gè)與眼影粉相反的紋線筆"，阿哈龍說(shuō)，"眼影粉含有重金屬，比如鉛，會(huì)對(duì)眼睛健康造成損害。"阿哈龍還建議避免閃光粉或金屬眼影進(jìn)入水線，因?yàn)檫@些顆粒具有刺激性。

When it comes to keeping your eyeliner clean of bacteria, Aharon says it's important tosharpen your pencil before each use."If your sharpener isn't handy, sterilize it by spraying itwith a little rubbing alcohol and clean of the tip with a tissue before application," she says."As long as you're properly sanitizing your eyeliner, it should keep fresh for a year or even two."

如果想要避免細(xì)菌感染，阿哈龍說(shuō)，重要一點(diǎn)是，在每次使用前削尖紋線鉛筆。"如果你的鉛筆刀是慣用的，那么就用噴霧器噴點(diǎn)酒精來(lái)消毒，在使用前用紙巾擦凈尖端，"她說(shuō)，"只要給你的眼線筆適當(dāng)消毒，就應(yīng)該能保持衛(wèi)生一年，甚至兩年。"
