Why do my eyes itch durring allergy season?

It really depends on how your body takes it.
Your body mistakes foreign objects, such as pollen or pet dander, as infectious agents. To prevent this possible infection, your body responds by releasing histamine, which can be related to the cause of allergic reactions. Common reactions are watery eyes, runny noses, coughing, or any other way that rids your body of the substance.
To prevent such a irritating experience, eat any number of medications that are offered as O.T.Cs. If you wonder how they work, on the back of the box there might be an ingredient called loratadine, which is an antihistamine which, well, gets rid of histamine that causes allergies. Nasal sprays personally work better for me. Source(s): Biology class = )

I have had the same problem all of my life and then I found out I am allergic to grass, and itchy eyes is my reaction. It happens during the spring and summer the most because that is when most people cut their grass the most often. i take Benedryl for my grass allergy, and I think you should consider a medication as well. Hope I helped!
My own experience of the same topic
I get this feeling you have allergies.
if allergy season is in sort of dry weather you could be getting "dry eyes". my brother gets that. when your're eyes dry out they itch. he usually uses eye drops.
