# What causes stinging sensation?

Stinging eyes feel sharply irritated, often when drops are applied or in harsh environments. It commonly reflects surface sensitivity or chemical exposure.

## Common Triggers

Dry eye and damaged epithelium make the surface more sensitive, so even normal tears or drops can sting. Preservatives, high-dose allergy drops, chlorinated water, smoke, and airborne irritants also provoke stinging.

- Newly prescribed drops may sting briefly but should not cause lasting pain
- Contact lens solutions placed directly in the eye can sting severely if not neutralised
- Eye rubbing after handling irritants transfers chemicals to the surface
- Post‑surgical eyes may sting until healing progresses

## Management

Switching to preservative‑free or better‑tolerated formulations, protecting the eyes from irritants, and treating underlying dry eye can reduce stinging. Chemical injuries or severe, sudden stinging demand urgent care.

- Report persistent stinging from prescribed drops to your clinician
- Rinse eyes with clean water or saline after accidental minor exposure
- Always follow instructions for contact lens solutions and avoid direct instillation
- Seek emergency help if vision drops or pain is severe after chemical contact
