Allergic conjunctivitis is a common condition that affects millions of people worldwide. It occurs when the eyes come into contact with an allergen, such as pollen, dust, or pet dander, triggering an allergic reaction. Understanding the symptoms of allergic conjunctivitis is crucial for proper diagnosis and treatment. In this article, we will delve into the world of allergic conjunctivitis, exploring its symptoms, causes, and treatment options.
The symptoms of allergic conjunctivitis can vary from person to person, but they often include redness, itchiness, and tearing of the eyes. In some cases, the condition can also cause swelling, burning, and sensitivity to light. If left untreated, allergic conjunctivitis can lead to complications, such as eye infections and vision problems. Therefore, it is essential to recognize the symptoms and seek medical attention if they persist or worsen over time.
Common Symptoms of Allergic Conjunctivitis
