If you get a hair in your eye, if some of the hair is exposed beyond the eyelid, you can gently remove it after washing your hands. If necessary, ophthalmology is consulted and the hair is removed by a doctor. Hair in the eye can cause the patient to experience discomfort such as a foreign body sensation and friction in the eye. The patient can look in the mirror to see if one end of the hair is exposed outside the eyelid, and if it is, after washing your hands, gently pinch the hair exposed outside the eyelid and take it out, which will alleviate the symptoms. If the hair is not exposed, rinse the eye with water or eye wash to remove the hair with the force of the water. If the above treatment does not relieve your symptoms, you should go to an ophthalmologist in a hospital to have your eye examined thoroughly to find the hairs and remove them.
