Wearing contact lenses and having a foreign body sensation after removing them may be related to poor hygiene, trauma, eye inflammation, etc. Depending on the cause of the disease, you should relieve the symptoms by rinsing with water and medication (levofloxacin eye drops, etc.). 1. Water rinsing: If you remove contact lenses when your hands are dirty, bacteria or particles from your hands will enter your eyes, causing discomfort and a foreign body sensation, so you can rinse your eyes with water to flush out the impurities. At the same time, it is important to change bad eye hygiene habits to avoid re-infection. 2. Medication: If there is a foreign body sensation in the eyes after removing contact lenses due to trauma, eye inflammation, etc., medication is needed. (1) Trauma: If you wear contact lenses with rough movements, the edge of contact lenses may scratch the cornea of the patient, resulting in obvious pain, tearing, photophobia and foreign body sensation, etc., you can use chloramphenicol eye drops, erythromycin eye ointment and other medications, and avoid rubbing the eyes. (2) Eye inflammation: If the patient’s eyes are infected by germs or bacteria, it will cause diseases such as conjunctivitis or keratitis, leading to symptoms such as dry and painful eyes, foreign body sensation in the eyes, and watering eyes, etc., which can be treated with levofloxacin eye drops and tobramycin eye drops. If you wear contact lenses and have a foreign body sensation after removing them, you should actively go to the ophthalmology department, do a systematic examination, clarify the cause of the disease, and follow the doctor’s instructions for treatment.
