Help docs! I'm trying to find out what causes eye allergy in children?

EYE ALLERGY: Eye allergy can be a part of general allergy- from food, airborne, smoke/allergens in the air, etc. Eczema, dry skin, dry eyelid margins also causes itching. Inverted eyelash can cause irritation, watery eyes and itching. Rubbing eyes makes it worse. Eyes become red, itchy with watery. If it bothers too much, check with the pediatrician/ ophthalmologist or allergist.
