Why does hay fever cause itchy eyes?
Hay fever causes itchy eyes mainly due to the body's allergic reaction to pollen or other allergens. When these allergens enter the eyes, they trigger the release of histamines, which lead to irritation and discomfort. This results in the sensation of itchiness as the eyes react to the presence of these allergens.
Key points:
- Allergens like pollen trigger an immune response.
- Histamines are released, causing irritation.
- Itchy eyes are a common symptom of hay fever.
- The reaction is part of the body's defence mechanism.
