Allergic conjunctivitis does not have a definite time for recovery, and patients can recover by removing themselves from the allergens and using anti-allergy medications as prescribed by the doctor. Allergic conjunctivitis tends to be seasonal, with onset in the spring or fall, after which it may resolve itself but still recur the following year. Patients may also have perennial allergic conjunctivitis, in which the allergy is present year-round and the condition may be mild or severe. Allergic conjunctivitis can recur after exposure to allergens and there is no definite time for healing. Allergic conjunctivitis is mainly due to an allergic reaction of the eye to the surrounding allergic substances, and is easily recurring, especially in children. Patients need to avoid contact with allergens as much as possible, and use medications such as sodium cromoglycate eye drops and flomilon eye drops as prescribed by the doctor to promote recovery. It is recommended that patients with allergic conjunctivitis should go to the hospital in a timely manner, and standardize the treatment under the guidance of the doctor.
