What’s the best way to treat seasonal allergies and itchy eyes?

Seasonal allergy itchy eyes can be treated with general treatment, medication, and desensitization.
General treatment includes detaching from the allergen, applying cold compresses locally or rinsing the conjunctival sac with saline to minimize the irritation of the allergic substances on the conjunctiva.
Medications include topical eye drops and systemic anti-allergy medications.
Topical medications include antihistamines, mast cell stabilizers, and non-steroidal anti-inflammatory drugs, such as Patanol eye drops, Azelastine eye drops, Emastine fumarate eye drops, Sodium cromoglycate eye drops, and Pralofen eye drops, etc. If treatment with the above medications is not effective, it can be used to reduce the irritation of the conjunctiva.
If treatment with the above medications is ineffective, glucocorticoid eye medications, such as fluticasone eye drops, may be considered for a short period of time.
If there is a combination of extra-ocular symptoms, you can consider the systemic use of anti-allergic drugs, such as loratadine tablets.
If the allergen has been clearly identified, you can consider using desensitization treatment.
Specific treatments are recommended to consult a doctor in time and follow the doctor’s instructions.
