Patients who suffer from allergies from time to time should avoid contact with allergens. If they have allergies from time to time, they should be more specific about the allergens they are in contact with. If the allergen has been isolated, anti-allergy medication can be used, such as topical application of Diamox eye ointment, oral systemic anti-allergy medication, such as loratadine or cetirizine systemic anti-allergy medication, and if the symptoms are heavy, cold compresses can also be applied to the eyelids to reduce the symptoms. If the eyelids are allergic to redness and swelling, you need to isolate the allergen and use medication, apply cold compresses and do not rub your eyes, and it will go down slowly.
