Pollen allergy

Pollen allergy, also called hay fever, causes problems such as red, itchy eyes, nasal congestion, repeated sneezing and runny nose. How severe the problems you get depends on how sensitive you are and how much and what types of pollen are in the air.
The pollen season lasts from early spring to late autumn and varies depending on where in the country you live. Prescription drugs can often alleviate the hassle, but not always completely remove them.
