Pronounced "akh eye", a symptom of the condition hayfever, where individuals suffering from said allergy react in varying ways to the presence of pollen in the air, notably in summer.

"Ach Aye" is the characteristic persistent itching of the eyes and the area around the eyes, and when serious is treated as a separate problem to the well known sneezing and constriction of airways.
