How come my eyes are itchy like 10 times everyday?

im thinking its my hair.. because its probably "poking" my eyelids making it itchy, and whenever i rub them REALLY hard, well u kno that red spot on ur eye, near ur eye boogers? yeah whenever i rub em real hard then that red part spreads and it sorta looks like i have pink eye, but its just a tiny pink spot but then it goes away. maybe im rubbing too hard, like if u scratch ur skin alot it turns red then dissapears. whats wrong with me? :S
