A swollen eye can look very dramatic. However, while it can seem alarming, it’s usually a fairly minor issue ‑ although sometimes it can indicate a more serious condition. Here, you'll learn about symptoms and causes of eyelid swelling, and treatment options for swollen eyes.
A swollen eye can look different depending on the causes. Here's one example.
A swollen eyelid is when your eyelids become puffy and enlarged. You might have only one swollen eyelid, or it could affect both. For people with lighter skin tones, the area may appear red or pink. On darker skin tones, the colour change might be less visible.
Swollen eye can be caused by many different things, including allergies, infections, inflammation, or injury.
Because your eye lid skin is very thin and flexible, even mild swelling can look quite pronounced.
In most cases, a swollen eye is mild and clears up on its own with simple home remedies. However, some situations may require medical attention. In rare instances, it could be a sign of a serious condition that needs immediate treatment.
Depending on the underlying causes, the symptoms of a swollen eye vary quite a lot. Below are some common symptoms people experience when they have a swollen eye.
Swelling may only affect one, but could affect both at the same time, it may start suddenly or develop over time.
Depending on the cause, you may get a swollen upper eyelid, a swollen lower eyelid, or swelling in just one part of one eyelid.

You might find it hard to move your eye, which can make looking up, down or side to side feel uncomfortable.
Depending on what's causing your swollen eye, you may also notice you get swelling in other parts of your face, hands, feet or limbs.
You may also notice bruising of the skin around the eye. The colour of the bruise will change over time. This is most common with a black eye.

The most common causes of a swollen eye include infections, inflammation, injury, allergic reactions, eye disorders, and other medical conditions. We’ll look at each of these in turn.
A swollen eye can happen when a bacterial or viral infection affects your eye or another part of your body.
A hordeolum or 'stye' is a small painful lump on the inner or outer surface of the eyelid. It is usually caused by bacterial infection in an eyelash follicle.

There are four sinus cavities in your face that produce mucus. When these become blocked (a condition known as sinusitis) it can cause swelling around the eyes.
This is a rare but serious condition that's caused by an infection of the fat and muscle around the eye. It progresses rapidly and requires urgent medical care.
Inflammation is your body's reaction to injury or infection. It can lead to a swollen eye if the eye, or the skin, muscles or tendons around it, gets affected.
This is a common condition in Australia. It happens when the thin layer of tissue that covers the front of the eye and inner surfaces of the eyelid (the conjunctiva) gets inflamed.

If something gets in your eye (such as a bit of dust, sand or smoke particles) it can cause eyelid inflammation.
You may get eyelid swelling if chemicals get into your eyes. This is common with household cleaning fluids and makeup, and is also a risk in some workplaces.
Injuries to the eye itself or the surrounding skin, muscles or tendons can cause a swollen lower eyelid or swollen upper eyelid.
A knock to the area around your eye sockets, forehead, or nose often results in a black eye. This causes swelling of the eyelids along with noticeable bruising.
Insect bites on the skin around your eyes can lead to significant swelling and puffiness.
Allergies are a major cause of swollen eye. Some kinds of allergic reaction are mild, but they can also be very dangerous and need urgent care.
Hay fever is an allergic reaction to pollen (from trees or grass, for instance) and can cause red, swollen eyes. Almost a quarter of Australians have hay fever, according to recent research.

Contact lens‑related issues may cause swollen eyes. A damaged contact lens, allergic reaction to lens solution, or minor injuries when putting lenses, can lead to swollen eyes.
Several other conditions can also cause swollen eyes ‑ including things that might not be directly related to the eye.
This is a rare thyroid disorder which makes the thyroid gland become overactive and causes hormonal imbalances. It can cause puffy eyelids or bulging eyes among other symptoms.
A few health conditions can make your body retain fluid, meaning that parts of your body appear puffy. It can affect eyelids as well as fingers, lips, feet, ankles and the lower back.
Some kinds of cancer that affect the eyes or other areas in the face can cause swollen eyes. Some types of cancer treatment may also make eyes appear puffy.
If your eyelids are swollen, it’s important to have it checked by an optometrist or your doctor. They’ll use various methods to learn more about what's happening.
Your optometrist or GP will ask about when the issue started, any other symptoms you've got, and how you're feeling generally.
An optometrist will use a few different methods to inspect the eye itself, including an OCT scan, a slit lamp test or dilated eye exam. Anyone with a valid Medicare card can get an eye test at any Specsavers store in Australia which is bulk billed to the government (meaning you don't pay).
If your optometrist, GP, or emergency department staff suspect certain conditions, they might refer you for a CT or MRI scan to get a clearer view of what’s going on around your eye.
Doctors may also take a blood sample and send it to the lab. This can help with identifying which kind of bacteria, virus or other issues are causing the swelling.
Book an eye testBook an appointment with your optometrist or GP if you've noticed any eyelid swelling. They'll decide how to get rid of a swollen eye, depending on what's causing it.
Below, we’ve outlined some potential home remedies for swollen eyes, along with treatments your optometrist or GP may suggest.
Eyelid swelling can often be treated with some simple home remedies. Still, it’s important to seek medical advice ‑ especially if you experience concerning symptoms like eye pain, sensitivity to light, or trouble opening the eye.
Use warm, soapy water to clean away any discharge or pus from your eyelid. Keep your eyes closed and gently wipe the area to clear any debris or pus.
Try applying a cold compress to your eyelids can help relieve soreness and inflammation. Try placing a cool, damp cloth over the affected eyelid.
If your swollen eye is caused by an allergy to things like pollen or pet hair, over‑the‑counter antihistamines can really make a difference.
If you get eyelid swelling after a chemical splash from makeup or cleaning fluids, wash your eyes out with cool, clean water for several minutes.
A swollen eye may need medical treatment. Depending on the cause, your doctor or optometrist might recommend some of the following methods.
Antibacterial eye drops can be a very effective treatment for inflamed and swollen eyes. They can resolve the infection and reduce irritation.
If your swollen eye is caused by a viral or bacterial infection, you may be prescribed a course of antibiotics that you'll take for a few days.
For severe allergies that cause serious reactions, your doctor will work with you to develop a management plan to help with managing the risk.
Sometimes, surgery may be required to treat the cause of a swollen eye. For instance, a blocked tear duct might need to be operated on.
Book an eye testThere are many things that can cause a swollen eye ‑ and many of them are out of your control. For example, if your swollen eye is caused by a grain of sand scratching the eye's surface and getting infected, this is hard to avoid. That being said, there are some general things you can do to reduce your risk.
Eyelid hygiene is important ‑ try to clean your eyelids daily with soapy water. Also, if you wear contacts, follow good contact lens habits (don't wear them too long, keep the lenses in their correct fluid, don't wear while swimming etc.). Also, avoid excessive eyelid rubbing ‑ even if your eyes are itchy.
Avoiding things that could cause eyelid swelling is also sensible. If you have allergies, avoid allergy triggers or take antihistamines before exposure. Wear helmets or eye protection when taking part in any risky sports, DIY or work where objects might get into your eyes.
There are many reasons your upper eyelid might become swollen. It could be caused by something like an insect bite. Other times, it might be related to specific eye conditions like styes or chalazion. A few other kinds of infection or injury might also be behind it. Your optometrist or GP can offer swollen upper eyelid treatment.
The white part of your eye is called the conjunctiva. When this area becomes inflamed it can look a bit like jelly. The most common reason for this swelling is conjunctivitis, which is an infection caused by a virus or bacteria. At Specsavers, we offer effective treatments for conjunctivitis.

Waking up with one eye swollen in the morning can be very alarming. If there was no obvious injury the day before, it might be caused by an insect (such as a mosquito) that bit you overnight. It could also be an allergic reaction to something like pet fur. Or, you may have an eye infection that developed overnight. Book an appointment with an optometrist to get this problem diagnosed.
Blepharitis may cause some swelling of the eyelid, itching, irritation or occasionally redness of the eye itself. The condition frequently occurs in those who have a tendency towards oily skin, dandruff or dry eyes.

It really depends on the cause. If it's caused by an insect bite, the swelling could last up to a week. Swelling from a black eye can last up to 3 weeks. Eyelid swelling from a stye will normally last 1‑2 weeks. Some eye conditions, like chalazion, can last up to a few months if left untreated. Visit your GP or optometrist to get a diagnosis ‑ they can give you a more accurate estimate for how long it will take to go down.
No, it's not usually a good idea to cover eyelid swelling. Covering a swollen eye can trap moisture and prevent air circulation, which can slow down healing time.
There's nothing to be ashamed of if you have a swollen eye ‑ it's very normal and almost everyone will get one at some point in their lives. All the same, it's completely normal to feel self‑conscious about a swollen eye. One option might be to wear sunglasses ‑ these will cover the eye and mean the swelling becomes less obvious. Usually, a swollen eye will clear up with treatment in a few days, so it's really valuable to book an appointment with your GP or optometrist. Swollen eye treatment should mean it goes down sooner and the eye will look normal again fast.
It depends on what's causing the issue. If your doctor believes that a bacterial infection is behind your swollen eye, then antibiotics (either in the form of eye drops, pills or even a drip) could be used. But if the swelling is caused by something like an insect bite, a scratch or a virus, then antibiotics won't help.
Eye tests are bulk billed to Medicare, so there are no out‑of‑pocket expenses for you*.
