> **Summary:** Stinging eyes usually happen when something irritates the eye surface: dryness, a foreign body, allergy, infection, strain or contact lens wear. It is often temporary and manageable at home, but lasting stinging can signal conditions such as keratitis, conjunctivitis or blepharitis and needs an eye examination.

## Why the Eye Stings
The cornea and the white of the eye must stay moist. If the tear system is disturbed, the surface dries out and stings; dryness and stinging often appear together.

## Common Causes
- **Contact lenses:** small objects or fibres on the lens and the drying effect of lenses cause stinging; hygiene matters.
- **Allergy:** most often pollen and dust, but also certain chemicals and foods, with redness, watering and stinging.
- **Dry eye:** often unnoticed. Dusty, dry or windy surroundings, heavy computer use, reading, strong light, hormonal conditions, infection and age all trigger it.
- **Eye strain:** from long exposure to light, screens and reading; causes pain and stinging.
- **Eye infection:** causes stinging and itching; needs a specialist to identify and treat.
- **Foreign body:** the eye waters to expel it; if it stays, it causes strong stinging, itching, redness and later headache.

## Conditions That Cause Stinging
- **Keratitis:** inflammation of the cornea, from infections caused by bacteria, viruses, fungi or parasites, poor contact lens hygiene or corneal injury.
- **Conjunctivitis:** inflammation of the conjunctiva, from viral, bacterial or allergic causes, with itching, redness and stinging.
- **Blepharitis:** chronic or temporary inflammation at the lash roots, a blockage or infection of the oil glands, with stinging, watering, redness and pain.

## Relief at Home
- **Contact lenses:** remove a lens that has been in for long hours and rest the eyes; keep the inner side clean when inserting.
- **Hygiene:** wash hands and face on waking, clean away overnight discharge and flakes, and remove make-up before sleep.
- **Rest:** take fifteen-minute breaks from reading, screens, sun and dry air.
- **Artificial tears:** recommended by a doctor for dryness; regular use clears dryness-related stinging.
- **Warm compress:** a warm cloth on the eyelids clears blockages at the lash base and in the eyelid oil glands.

A doctor should still confirm whether the situation is serious.
