In addition to itching and tearing, what is another common symptom of allergic conjunctivitis?

Puffiness around the eyes is indeed a common symptom of allergic conjunctivitis. This condition occurs when allergens cause the eyes to become inflamed, leading to swelling of the tissues surrounding the eyes, often referred to as periorbital edema. Itching and tearing are often associated with this allergic reaction, but the inflammation can also contribute to noticeable puffiness around the eyes, which is a response to the body's immune reaction to allergens. This can manifest as redness and swelling, making it a key symptom in diagnosing allergic conjunctivitis.

Persistent fogging of vision, severe pain in the eye, and excessive tearing alone do not typically align with the general presentation of allergic conjunctivitis. While excessive tearing can occur, it usually accompanies other symptoms rather than standing alone. Therefore, the presence of puffiness further supports the diagnosis and understanding of allergic conjunctivitis.
