Yes, allergies can cause dryness, particularly in the eyes.
Allergic reactions can trigger a cascade of events that ultimately lead to feelings of dryness and irritation. Here's how:
- Increased Tear Evaporation: Allergic reactions can stimulate the eyes to produce excessive tears. Paradoxically, these tears may evaporate quickly, leaving the surface of the eye feeling dry.
- Conjunctivitis and Inflammation: Prolonged exposure to allergens can inflame the conjunctiva, the thin membrane covering the white part of the eye. This inflammation can disrupt tear production and lead to dryness and discomfort.
Therefore, while allergies are often associated with watery eyes, they can also contribute to dry eyes due to the instability of the tear film and inflammatory processes.
