Eyelashes entering the eye and not coming out may have certain effects. Long-term stimulation of foreign bodies in the eye may result in symptoms of conjunctivitis such as tearing and increased secretion, and it is recommended that they be removed promptly. Eyelashes often fall out due to external forces or normal metabolism. When eyelashes enter the eye, do not rub them with your fingers because they are contaminated with more bacteria and microorganisms, and rubbing them at this time may aggravate eye discomfort and may mechanically damage the corneal epithelium, increasing the chance of eye infection. In most cases, the eyelashes will come out under the flushing effect of tears, so there is no need to worry too much. If they do not come out, it is more effective to flush the eye with plenty of water or saline. If these methods fail to remove the eyelashes and symptoms such as photophobia and burning sensation occur, it is recommended that you go to the hospital in a timely manner and have the eyelashes removed by a doctor with the help of professional medical equipment. In daily life, you can protect your eyes by wearing glasses to avoid foreign objects such as dust and sand from entering and causing eye discomfort. For people who use their eyes excessively for a long time, it is also important to pay attention to eye protection by performing eye exercises in moderation and properly looking into the distance so that the eyes can get sufficient rest.
