It depends on the cause of the itchiness, however wet tea bags on the eyes can be very soothing due to something in the tanin. If it doesnt help - you may need to consult a vet to make sure there's nothing in the eyes that needs flushing out, and possibly get some cream in case of infection.
It wont hurt to try the wet, luke-warm tea-bags first tho :)
