Whether or not a watery film in the eye can heal on its own depends on the specific cause of the condition. Overuse of the eyes, staying up late, and drinking before bedtime may cause edema, and rubbing the eyes with the hands may cause irritation, at which point the film will generally heal itself with rest. The following conditions may also cause watery film to bulge in the eyes and cannot heal on their own: 1. Keratitis: patients with keratitis mainly show symptoms of eye irritation, such as pain, tearing and cramping, while causing blurred vision, like a layer of watery film covering the eyes, which generally does not heal on its own. However, it can be treated with medications such as flucytosine and levofloxacin eye drops under the guidance of a doctor, or surgical treatment. 2. Iris ciliary inflammation: It can be accompanied by symptoms such as redness of the eyes, photophobia, blurred vision, and when deposits appear behind the cornea, it can appear membranous. It can be treated with glucocorticoid eye drops such as dexamethasone and flutrione, as well as anti-inflammatory treatment such as bromfenac sodium under the guidance of a doctor, and cannot be self-cured; 3. Glaucoma: the precursor phase of acute closed-angle glaucoma attack, also known as the petit mal phase, often causes blurred vision and a hooded feeling in patients, like a layer of watery mist in the eyes. Glaucoma cannot be cured by itself, but must be treated to slow its progression and vision loss. In the acute stage, it is often used to shrink the pupil with frequent topical drops of Mao Guo Yunxin, and glycerin and isosorbide can reduce the intraocular pressure. 4. Acute conjunctivitis: the onset of the disease is usually rapid, mainly manifested as eye congestion, pain, increased secretions and other symptoms, when the inflammation develops to the cornea, it can cause blurred vision, and the surface of the lid conjunctiva can be covered with a white pseudomembrane, which is not self-healing, but the prognosis is generally better after treatment. In addition, diseases such as pterygium, dry eye, cataract, and bulbar conjunctival edema caused by orbital cellulitis and blockage of orbital lymphatic vessels can also cause an aqueous membrane to bulge in the eye, which cannot heal on its own and should be treated promptly and aggressively under the guidance of a physician.
