Your eyelashes aren't just decorative; they also act as a barrier that prevents dust, dirt, and other small particles from entering your eyes and causing irritation or injury. When an object approaches your eyes, your eyelashes also trigger the blink reflex, providing an extra layer of protection while reducing airflow to the ocular surface, which can help prevent dry eye and maintain hydration. As we've already explained, eyelashes have a life cycle, just like any other hair. Taking care of them not only makes them look their best, but also helps them fulfill their function effectively. So, while we love the beauty of our eyelashes, don't forget that they're also there to protect your precious eyes!
