White film in the eyeball and pain may be caused by allergic conjunctivitis, infectious keratoconjunctivitis, and abnormal growth of the eye surface. 1. Allergic conjunctivitis: allergens such as pollen and dust can cause symptoms such as itching and tearing, as well as signs such as conjunctival congestion and increased secretion, which may be sticky and cloudy, forming a white film, and blurred vision when symptoms are severe. 2. Infectious keratitis: keratoconjunctivitis caused by pathogenic bacterial infection of the eye surface, usually manifested as eye pain, tearing, increased secretion, causing vision loss in severe cases, the secretion is mostly purulent or mucous, forming a white film, antipathogenic bacterial treatment, such as the use of antibiotics, such as levofloxacin and so on. 3. Abnormal hyperplasia of the ocular surface: Due to the high distribution of corneal nerves, the whole layer of the cornea can not be completely regenerated, the pain is obvious after trauma to the ocular surface, and the formation of corneal scar, which manifests itself as leukomembrane of the ocular surface in severe cases. Once the white membrane appears in the eye, and also when it hurts, go to the hospital in time, after professional examination, to clarify the cause of the disease, and standardized treatment for the cause of the disease.
