Could allergies cause film and discharge through the eyes?

Yes: Eyes are very often the target of allergies.Try an otc antihistamine like claritin (loratadine).

Definitely!: Allergic conjunctivitis creates stringy mucus discharge and eye redness. Splash cool water on your eyes when you come in from outdoors... That can remove pollen and other allergens from your lashes where they cause allergies. A prescription antihistamine drop can help also.
