眼線筆會損害你的眼睛嗎?

You might want to think twice before layering on your eyeliner at your lower lash line. A new study in the Eye and Contact Lens journal found that using eyeliner on your inner lash line may put you at risk for infection and Vision trouble.

用眼線筆畫下眼線前你可能要三思而後行。《眼睛和隱形眼鏡》雜誌的一個新的研究發現，使用眼線筆畫內眼線可能會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 Optometry and Vision Science in the Faculty of Science at Waterloo, who used video recordings to track the migration 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 their waterline. "We noticed the makeup migration happened quicker and was greater when the eyeliner was put on the inner lid," says Ng.

這項研究由滑鐵盧科學院光學和視力學博士後艾莉森主導，她使用視頻跟蹤眼線膏在紋過眼線的眼睛中的移動軌跡。實驗人員在外眼線上使用閃光眼線筆，然後再畫到水線。 "我們注意到其中的成分在到達眼瞼時移動突然加速，影響也在加強。"

When the liner was applied to the inner lash line, 15-30 percent more particles entered the tear film—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 with dry or sensitive eyes to more serious infections and blurred vision. "People who wear contact lenses are most likely to notice some problems," says Ng. "If they have eyeliner stuck to their lenses, increasing deposits might cause vision disruption as the lens becomes cloudier."

當眼線膏被畫在內眼線上時，進入淚液膜——眼睛裏薄薄的保護膜——的成分比畫在外眼線上時多出15-30%。眼線膏進入淚液膜後可能會造成眼球乾澀敏感，嚴重會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，"如果有眼線膏附着在隱形眼鏡上，不斷增加的沉積物會導致視力雲狀模糊。"

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

還想繼續畫內眼線嗎？紐約市化妝師麗莎·阿哈龍說，還是有辦法減少感染風險的。"當在你的水線上使用眼線筆時，找一個與眼影粉相反的紋線筆"，阿哈龍說，"眼影粉含有重金屬，比如鉛，會對眼睛健康造成損害。"阿哈龍還建議避免閃光粉或金屬眼影進入水線，因爲這些顆粒具有刺激性。

When it comes to keeping your eyeliner clean of bacteria, Aharon says it's important to sharpen your pencil before each use. "If your sharpener isn't handy, sterilize it by spraying it with 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."

如果想要避免細菌感染，阿哈龍說，重要一點是，在每次使用前削尖紋線鉛筆。"如果你的鉛筆刀是慣用的，那麼就用噴霧器噴點酒精來消毒，在使用前用紙巾擦淨尖端，"她說，"只要給你的眼線筆適當消毒，就應該能保持衛生一年，甚至兩年。"
