Is Your Eyeliner Endangering Your Vision? Here’s What You Need to Know

For numerous individuals, the application of eyeliner serves as an avenue to express their flair and fashion sense. However, recent research suggests that your technique could inadvertently jeopardize your eye health. Understanding improper application can help preserve your vision without eliminating your cosmetic routine. The study reveals that eyeliner often infiltrates the tear film—a delicate protective layer on the cornea composed of three components: an oily surface layer, an aqueous middle, and a mucous base. Researchers found that applying eyeliner directly along the inner lid intensified the migration into this tear film, with 15 to 30% of glitter-based eyeliner particles entering within five minutes. Symptoms of disrupted tear film include dryness, discomfort, and blurry vision. Those with dry or sensitive eyes and contact lens wearers are particularly susceptible. Experts advise against the waterlining method and recommend using sharpened or fresh applicators to minimize irritation and potential infections. Caution with glitter is also advised, as its particles may contribute to eye issues.
