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.
用眼线笔画下眼线前你可能要三思而后行。《眼睛和隐形眼镜》杂志的一个新的研究发现，使用眼线笔画内眼线可能会造成感染和视力问题。
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.
这项研究由滑铁卢科学院光学和视力学博士后艾莉森主导，她使用视频跟踪眼线膏在纹过眼线的眼睛中的移动轨迹。实验人员在外眼线上使用闪光眼线笔，然后再画到水线。 "我们注意到其中的成分在到达眼睑时移动突然加速，影响也在加强。"
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."
当眼线膏被画在内眼线上时，进入泪液膜——眼睛里薄薄的保护膜——的成分比画在外眼线上时多出15-30%。眼线膏进入泪液膜后可能会造成眼球干涩敏感，严重会造成感染和视力模糊。"戴隐形眼镜的人更容易感觉到问题，"艾莉森说，"如果有眼线膏附着在隐形眼镜上，不断增加的沉积物会导致视力云状模糊。"
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.
还想继续画内眼线吗？纽约市化妆师丽莎·阿哈龙说，还是有办法减少感染风险的。"当在你的水线上使用眼线笔时，找一个与眼影粉相反的纹线笔"，阿哈龙说，"眼影粉含有重金属，比如铅，会对眼睛健康造成损害。"阿哈龙还建议避免闪光粉或金属眼影进入水线，因为这些颗粒具有刺激性。
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."
如果想要避免细菌感染，阿哈龙说，重要一点是，在每次使用前削尖纹线铅笔。"如果你的铅笔刀是惯用的，那么就用喷雾器喷点酒精来消毒，在使用前用纸巾擦净尖端，"她说，"只要给你的眼线笔适当消毒，就应该能保持卫生一年，甚至两年。"
