Dry eye syndrome - Self help 

There are several self-care techniques that can be used to help prevent or reduce the symptoms of dry eye syndrome.

Keep your eyes clean

Good eye hygiene will help prevent dry eye syndrome and the associated condition of blepharitis, which is inflammation (redness and swelling) of the rims of the eyelids.

To clean your eyes:

• wet a cloth with warm water and hold it against your closed eyes for five to ten minutes
• massage your eyes by gently rolling your first finger over them in a circular motion - this will help to push out any of the mucus-like fluid from the tiny eyelid glands
• gently clean your eyelids using cotton wool and hot (but not boiling) water - a cotton bud can also be used to clean your upper and lower eyelid and remove any crustiness

See the Health A-Z topic about Blepharitis - treatment for more information about treating this condition.

Protect your eyes

Certain environments can irritate your eyes. Keep your eyes protected eyes from:

• wind
• hot air
• smoke

Wraparound glasses may provide good protection. Avoid smoky environments and, if you smoke, try to quit.

Adjust your computer

Make sure that your computer workstation is positioned correctly in order to minimise eye strain. Most companies have a health and safety officer or representative who can advise you about this. Your monitor (screen) should stand at eye level or just below it.

If you use a computer, make sure that you take enough breaks away from your computer screen, and blink your eyes regularly. Taking breaks every hour to rest your eyes may help to reduce your symptoms.

Use a humidifier

A humidifier at work and at home will moisten the surrounding air. If you cannot afford a humidifier, lightly spray your curtains with water several times a day to help keep the air moist.

Open the windows for a few minutes on cold days, and for longer in the spring and summer. This will also help to keep the air moist and prevent the build-up of mould.

Diet

There is evidence to suggest that a diet high in omega-3 fats can help to prevent dry eye syndrome. The exact reasons for this are unclear, but it is known that omega-3 fats are used in the production of tears.

The best source of omega-3 fats are oily fish such as:

• mackerel
• salmon
• sardines
• herring
• fresh tuna (not canned because the canning process removes the beneficial oils)

Aim to eat at least two portions of fish a week, one of which should be oily fish.
