When eyes are exposed to pollen or mold, they become red, itchy, or watery. Which condition is this?

• A. Conjunctivitis
• B. Allergic Conjunctivitis
• C. Foreign Object in the Eye
• D. Cataract

Answer: (B)

This question tests recognizing allergic conjunctivitis, an eye inflammation triggered by environmental allergens such as pollen or mold. Exposure to these allergens prompts an immune response in the conjunctiva, releasing histamine that causes itching, redness, and watery discharge. The itching that accompanies allergen exposure is a key clue that this is allergic conjunctivitis, rather than other eye problems. A foreign object in the eye would typically cause irritation and pain and a sensation of something in the eye. Cataracts cause gradual vision changes due to lens clouding, not acute redness, itching, or tearing tied to allergen exposure. Infectious conjunctivitis can cause redness and discharge too, but itching is usually less prominent and the discharge tends to be purulent. So the combination of red, itchy, and watery eyes after pollen or mold exposure best fits allergic conjunctivitis.
