What are dry eyes?
Dry eyes is a common problem. But most people with dry eyes have mild symptoms.
You can get dry eyes if you don't make enough tears, or if your tears dry up too quickly.
What symptoms are related to dry eyes?
Dry eyes can make your eyes:
- sore
- gritty
- sting or burn
- look red
- sensitive to light
Your vision (eyesight) may also be blurry.
Sometimes dry eyes can cause excess tearing (watery eyes). You might also have blepharitis (inflamed eyelids).
You may feel like something is in your eye and you may have difficulty wearing contact lenses.

What causes dry eyes?
The surface of your eyes is kept moist with a layer of tear film. This tear film is made up of 3 layers:
- fatty oils
- watery tears
- mucus
When your tears are working normally, these 3 layers keep your eyes smoothly lubricated. If you have a problem with any of these 3 layers, you may develop dry eyes.
You can also develop dry eyes if your tear glands don't make enough watery tears.
You can also develop dry eyes if there are problems with the glands above your eyes called the 'meibomian glands'. These glands make the oily tear film layer that stops your tears from evaporating. If these glands don't work normally, your tears may evaporate too fast, drying out your eyes.
Dry eyes may also be caused by a combination of these problems.
You are at increased risk of dry eyes if you:
- are female
- are aged 50 years or older
- wear contact lenses
- use a computer or other screen for long periods of time
- suffer from an autoimmune condition such as Sjogren's syndrome, scleroderma, lupus or rheumatoid arthritis
- take certain medicines
- are exposed to smoke, wind or dry air
How is the cause of dry eyes diagnosed?
Your doctor will examine your eyes and ask questions about your symptoms. They will also want to know about any medicines you take and your medical history.
If you see your optometrist, they may give you eye drops to dilate (widen) your pupil to check for problems.
Your doctor may refer you to an ophthalmologist (eye doctor).

How are dry eyes treated?
Treatment for dry eyes usually depends on what's causing your symptoms.
The aim of treatment is to relieve symptoms and reduce the chance of damage to the surface of your eye.
Self-care at home
Eye lid hygiene and warm compresses may be recommended, particularly if you have meibomian gland problems or blepharitis.
Ask your doctor or optometrist for advice for your symptoms.
Medicines for dry eyes
Ocular lubricants (tear supplements) in the form of eye drops, gels or ointments are available to buy over-the-counter.
Eye drops are applied 3 to 4 times a day. Gels provide longer relief, but can blur your vision for a while.
Ointments can be used at night if symptoms affect your sleep or are worse in the morning.
Check with your pharmacist or optometrist for the most suitable option.
If your symptoms persist or are severe, your doctor may refer you to an ophthalmologist who may prescribe anti-inflammatory eye drops.
Can dry eyes be prevented?
Here are some things you can do to manage symptoms or prevent dry eyes:
- Avoid straining your eyes — limit screen time and take breaks to rest your eyes.
- Protect your eyes — wrap-around glasses can help you avoid direct contact with wind, hot air, direct sunlight and smoke.
- Use a humidifier at home or at work — this stops the air becoming dry.
- Don't smoke or drink too much alcohol.
- If you wear contact lenses, try to reduce the number of hours you wear your lenses.
Complications of dry eyes?
Most people respond well to treatment, but some people may develop:
- scarring or the part of the eye called the cornea
- vascularisation (growth of blood vessels) in your eyes
- long-term vision problems
