Dry eye disease: symptoms, causes and treatment
Dry eye disease is a condition where your eyes don't produce enough tears — or the right kind of tears — to stay moist and comfortable. The good news: it can often be managed once it's recognised.
What is dry eye disease?
Your tears keep the front of your eye smooth, clear and comfortable. With dry eye, the tear film isn't enough to do that job, so the eyes feel dry, irritated or tired.
Common symptoms of dry eye
- A feeling of dryness or grittiness in the eyes
- Red, irritated or itchy eyes
- Watery eyes (due to irritation)
- Blurry vision that improves with blinking
- Sensitivity to wind or smoke
What causes dry eye?
- Age — tear production can change as we get older
- Environmental factors, such as wind or smoke
- Certain medications
How is dry eye managed?
Dry eye can often be managed with eye drops, lifestyle changes or other treatments that help keep your eyes comfortable. The right approach depends on an examination of your eyes, so it's worth getting them checked rather than guessing.
When to see an eye care professional
If you notice any of these signs, book an eye examination with an eye care professional. Early assessment makes it easier to manage most eye conditions.
