Do any of these scenarios sound familiar?
You catch a whiff of a co-worker's new fragrance, and within minutes, you have a whopper of a headache.
You pop open that new bottle of dish-washing liquid, and by the time you've washed the pots and pans, your hands and arms are covered in hives.
You walk into a friend's home and smell freshly baked pumpkin pie. Only after you start sneezing uncontrollably and feeling dizzy, weak, and sick to your stomach do you learn she hasn't been baking --...
There are several different causes for this. But for the most part, if you're allergic to a particular substance and then come into contact with it, you have an allergic reaction like itching and sneezing.
Causes of Eye Allergies
That layer of skin covering the front of your eyes? It’s the same type of skin that lines the inside of your nose. Because these two areas are so similar, the same things can trigger allergic reactions in both places.
If you have seasonal allergies, you generally have symptoms for a short time. You may be bothered in the spring by tree pollen, in the summer by grass pollen, or in the fall by weed pollen. The symptoms tend to clear up during other times of the year, especially in the winter.
If you have "perennial allergies," your symptoms probably last all year. You're likely allergic to indoor things, like dust mites, cockroaches, and pet dander. Seasonal outdoor allergens may make things worse if you’re sensitive to them, too.
Seasonal and perennial allergies have identical symptoms and, almost always, itching lets you know you’re having an allergic reaction.
