One is their own allergy, most patients have a history of allergic rhinitis and bronchial asthma. These people usually have an attack in the spring, when they are exposed to allergens, and the symptoms are relieved or disappear soon after they are removed from the allergen.
There are also incorrect lifestyle habits that lead to damage to the tissue cells of the eye itself. For patients who wear corneal contact lenses, it is important to replace the contact lenses, choose rigid contact lenses with higher permeability, shorten the wearing time, strengthen the care of the contact lenses, avoid using care solutions containing preservatives and heavy metals with potential antigenic activity, and stop wearing the contact lenses during the period of worsening inflammation.
If the allergy is caused by a drug, the drug should be discontinued immediately.
