If hair falls into the eye, you can open the eyelid and flush it with saline, and if you have difficulty flushing it out by yourself, you should go to the hospital in time. If you don’t have sterile saline at home, you can also use cooled boiled water or eyewash to rinse. When rinsing, be careful to open the eyelids and turn the eyeball while rinsing in order to flush out the broken hair. The foreign body can usually be flushed out by rinsing, but if the foreign body sensation is still obvious after rinsing, do not rub your eyes vigorously, in order to prevent the hair that has not been removed from penetrating deeper into the conjunctiva or the conjunctival sac. Patients should consult the ophthalmology clinic of the hospital in a timely manner and have the foreign body removed with the assistance of a slit lamp. It is recommended that patients with foreign bodies in the eye should seek prompt medical attention to assess their condition and follow medical advice.
