Eye Discharge

Overview

Eye discharge is the gunk, crust, or fluid that can collect in the corner of your eye or on your eyelashes. It can be clear and watery or thick and sticky. A little discharge after sleep is normal, but a change in the amount, colour, or how your eye feels can be a sign to get advice. Eye discharge is a symptom, not a diagnosis on its own.

Yes. Many people get eye discharge at some point. It is one of the most common reasons people ask a pharmacist or doctor about eye problems.

Anyone can get eye discharge. It is especially common in babies with blocked tear ducts, in children with viral infections, and in older adults with dry eyes or eyelid problems.

Symptoms

Common symptoms

• Watery or sticky fluid in the eye
• Crusting on the eyelashes, especially after sleep
• A gritty, burning, or itchy feeling
• Redness in the white part of the eye
• Mild swelling of the eyelids
• Blurred vision that clears when you blink or wipe the eye

Symptoms in children

• Sticky or watery eyes are common in newborns because tear ducts can be narrow or blocked.
• Children often get viral conjunctivitis (pink eye) along with a cold.
• Crusting can make it hard for a child to open their eye in the morning.
• Children may rub their eyes more when they have allergies.

Symptoms in older adults

• Dry eyes can cause a stringy or watery discharge.
• Blepharitis (eyelid inflammation) can cause crusting and irritation.
• Eyelids that turn inward or outward can make discharge more likely.
• Older adults may have more eye infections or tear duct problems.

Causes

Main causes

• Viral conjunctivitis (pink eye), often with a cold
• Bacterial conjunctivitis
• Allergies such as pollen or dust
• Blocked tear duct, especially in babies
• Dry eye
• Blepharitis (inflammation of the eyelids)
• Irritants like smoke, shampoo, or a foreign body
• Contact lens problems

Risk factors

• Touching your eyes with unwashed hands
• Sharing towels, pillows, or eye makeup
• Wearing contact lenses, especially if you clean or store them incorrectly
• Having allergies or dry eyes
• Being around someone with a contagious eye infection
• Having a cold or upper respiratory infection
• Older age or eyelid problems
• Being a newborn with narrow tear ducts

When to see a doctor

See a doctor urgently if:

• You have eye pain or sensitivity to light
• Your vision suddenly changes or becomes blurred
• Your eye is very red, especially if you wear contact lenses
• The discharge is thick, yellow, or green and getting worse
• A newborn baby has a red, swollen eye with discharge
• Symptoms do not improve after a few days of simple care

Book a routine appointment if:

• Discharge keeps coming back
• One eye is always watery
• Eyelid crusting does not clear up
• You want advice about allergies or dry eyes

Diagnosis

A doctor or eye care professional can usually tell what is causing eye discharge by asking about your symptoms and looking closely at your eyes. They may check your vision, shine a light in your eyes, and look at your eyelids and lashes. Most people do not need special tests.

Tests that may be done

• A swab of the discharge, if an infection is suspected and treatment needs guiding
• A slit-lamp exam (a special microscope for the eye)
• A test for dry eye or allergy
• Checking contact lens fit and care
• Sometimes a test to check for blocked tear ducts

What to expect at your appointment

The check is quick and gentle. Your doctor will ask when the discharge started, what colour it is, and whether you have pain, itching, or vision changes. They will explain what they think is happening and whether you need treatment or simple care.

Treatment

Treatment depends on the cause. Many people get better with simple home care. If an infection or allergy is the cause, a doctor or pharmacist can suggest the right approach. Always ask before using any eye product.

Self-care at home

• Wash your hands before and after touching your eye or cleaning your eyelids.
• Use a clean, warm, damp cloth to gently wipe away crust from the eyelashes. Use a new cloth for each eye.
• Do not rub your eyes.
• Stop wearing contact lenses until the eye is better and your eye care professional says it is okay.
• Do not share towels, pillows, or eye makeup.
• Use cool compresses for itching or swelling, and warm compresses for crusting.
• Avoid smoke, dust, and other irritants.
• If you use eye drops, ask a pharmacist which type is right for you. Do not use someone else's drops.

Medical treatments

If a bacterial infection is suspected, a doctor may prescribe treatment to clear it. For allergies, they may suggest allergy treatment. For dry eye, they may recommend lubricating eye products or other ways to keep the eye moist. For blepharitis, regular eyelid cleaning is often the main treatment. A doctor will choose the approach based on your age, symptoms, and health.

When is surgery considered?

Surgery is rarely needed. It may be considered if a tear duct stays blocked, if an eyelid problem keeps causing discharge, or if there is another structural problem. Your eye specialist would discuss this with you.

Living with this condition

Keep your hands clean and avoid rubbing your eyes. If one eye is infected, use separate towels and try not to touch the other eye. Follow any advice from your pharmacist or doctor about contact lenses and eye makeup. Most people can carry on with normal life while they recover.

Lifestyle tips

• Wash your hands often, especially before touching your face.
• Keep contact lenses and cases clean, and replace them as advised.
• Avoid sharing personal items like towels and eye makeup.
• Manage allergies by keeping windows closed when pollen is high and washing bedding regularly.
• Take screen breaks and blink often if your eyes feel dry.
• Use good lighting and avoid smoke.

Diet and exercise

There is no special diet that cures eye discharge. Eating a balanced diet and drinking enough water supports general health. Regular exercise is good for your overall health, but avoid swimming with an eye infection until it has cleared.

Mental health and emotional wellbeing

Eye problems can be annoying and sometimes worrying, especially if they affect your vision or keep coming back. It is okay to feel frustrated. If you feel very anxious or low, talk to your doctor. If you are in crisis, contact your local crisis support service or emergency services.

Prevention

You cannot prevent every cause, but good hand hygiene and careful contact lens care lower the risk. Avoiding irritants and managing allergies also helps.

Vaccines

There is no vaccine that prevents most causes of eye discharge. Some infections that can affect the eyes, like measles, can be prevented by routine vaccines, so keep up with the vaccines your health service recommends.

Screening programmes

There is no routine screening test for eye discharge itself. If you have diabetes or another condition that affects the eyes, keep up with your regular eye checks.

Complications

If left untreated

• A bacterial infection can spread or, rarely, damage the surface of the eye.
• Contact lens-related infections can be serious if not treated quickly.
• A blocked tear duct can cause repeated infections.
• Long-term dry eye or eyelid problems can make discomfort continue.
• Some eye infections are contagious and can spread to others.

Long-term outlook

Most eye discharge improves quickly with simple care or treatment. Even when it needs medical help, the outlook is usually good. If symptoms are severe or not getting better, get advice early.
