What Is Allergies?
Allergies are your body’s natural response to certain medications or substances, usually resulting in itchiness, redness, and inflammation, among other symptoms. They may occur during particular seasons of the year, or year round, depending on what you’re allergic to. If you suffer from allergies, your eyes may be affected, too. They may be red, itchy, and watery and your eyes and eyelids may even be inflamed.

What Causes Allergies?
When your body comes into contact with an allergen or certain medications, your immune system naturally reacts, producing a chemical called a histamine. Histamine binds to tissue in the eyes, causing them to enlarge or dilate, which manifest as the symptoms of allergies.
Common allergens affecting the eyes include, but are not limited to, pollen, ragweed, grass, mold, weeds, dust, and pet dander.
