Eye allergy (Allergic Conjunctivitis) is an overreaction of the eye membrane to environmental factors such as pollen, dust, and pet dander. The body's defense system produces antibodies against these substances, leading to the secretion of histamine, which causes itching, watering, and redness.
Symptoms of Eye Allergy
- Severe itching and stinging sensation
- Redness and veining in the eye
- Swelling in the eyelids
- Sensitivity to light
Prevention and Treatment Methods
The best treatment is to stay away from the allergen. However, since this is not always possible, applying cold compresses and using antihistamine drops controlled by a physician quickly relieve symptoms. Absolutely avoid rubbing the eye; because rubbing both increases itching and can invite permanent diseases like keratoconus by damaging the cornea.
