Allergies can occur in your body but also specifically in your eyes!
When your eye comes into contact with something that it is allergic to such as pollen or cat dander, it may produce an inflammatory response leading to itching, redness or sometimes even swollen eyes. When this occurs, make sure you do not rub your eyes because it can cause the irritation to worsen. Additionally, you should follow up with your eye doctor to consider treatment options such as artificial tears, allergy drops or cold compresses.
