Try nonprescription "artificial tears," a type of eye drop that may help relieve itching and burning (note: Other types of eye drops may irritate the eyes and should not be used). Do not use the same bottle of drops in the other eye if it is not affected.
The best defense against allergic pink eye is a good offense: Try to avoid substances that trigger your allergies. An allergy specialist can test to determine what your specific triggers might be.
