What are Puffy Eyes?
Puffy eyes happen when the skin around your eyes swells, often in the morning. It’s usually harmless and goes down on its own, but it can also be linked to allergies, infections or other eye conditions.
What are the symptoms of Puffy Eyes?
Most people will get puffy eyes now and then. But if your eyes are swollen, sore or red, you may also have other symptoms depending on the cause. These could point to an allergy, an infection, or a different condition entirely. Let’s look at some of the most common symptoms of eye puffiness:
Puffiness under the eyes: Noticeable swelling below the eyes, especially after sleep or crying. It often makes your eyes look tired or bloated.
Eyes swollen in the morning: Waking up with puffier eyelids is common. It usually eases as you move around, but if it doesn’t, it may need checking.
Eye pain: Puffiness with pain may be a sign of something more serious.
Watery eyes: Tear build‑up can make puffiness worse.
Red or irritated eyes: If the skin or white of your eye looks red too, it could be linked to irritation or infection.
Itchy or dry feeling: Could be linked to an allergy or dryness.
Grittiness or stinging. Often a sign of irritation, infection or inflammation.
Swelling that won’t go away. Could be a chalazion or stye. These may need treatment if they don’t improve.
What causes puffy eyes?
Puffy eyes may be short‑term or persistent and need a closer look.
Fluid build‑up:
Lying flat, not blinking much, or having too much salt or alcohol can cause fluid to collect under the eyes, especially overnight. That’s why your eyes might be puffy in the morning.
Allergies:
Allergies to hay fever, pet dander, or dust can all cause puffiness around the eyes. You may also notice itching, watering or redness.
Infections and inflammation:
Conditions like conjunctivitis, styes, blepharitis or a chalazion can lead to swelling, pain or redness around the eyelids.
Crying:
After a long cry, tear glands work overtime and can cause swelling under the eyes. This usually settles after a few hours.
Lack of Sleep:
Poor rest can slow fluid drainage and make puffiness more obvious. It may also make skin look paler, which makes puffiness stand out more.
Eye strain or tiredness:
Poor sleep, eye strain, too much screen time, or rubbing your eyes can all make puffiness worse.
Ageing:
As you get older, skin and muscle tone change. Fatty tissue can move into the lower eyelids and cause permanent puffiness or bags.
Genetics:
Some people are more likely to have puffiness under the eyes, especially if family members have it too. This often shows up from your 30s onwards.
Medical conditions:
Long‑term puffiness can be caused by thyroid eye disease, kidney problems or sinus issues. It’s worth speaking to a doctor if puffiness appears suddenly or worsens.
Skin Conditions:
Issues like dermatitis or eczema around the eyes can cause puffiness, especially if the skin becomes inflamed or irritated.
Injury or trauma:
Any knock to the eye can cause swelling, bruising or tenderness. If you’ve had an injury, always get it checked to rule out anything more serious.
How are Puffy Eyes treated?
Puffy eyes are usually checked during a routine eye test. Your optometrist will look at the skin around your eyes, ask about any symptoms you’ve noticed, and explore possible causes. Most of the time, no specialist tests are needed, but if the puffiness is ongoing or unusual, they may recommend extra checks.
We’ll start with a visual check, looking at the area around your eyes for signs of swelling, redness or irritation. If there’s visible puffiness, we’ll assess whether it’s mild or more advanced. You’ll also be asked about any discomfort, such as itchiness, pain, changes to your vision or light sensitivity. These details help us work out what might be going on.
We’ll then talk through your medical background, including any allergies or previous eye problems. This gives us a better idea of what could be causing the puffiness. If we think something else might be behind it, we may refer you for extra tests. These could include blood tests (to rule out thyroid or kidney problems), allergy tests, a skin biopsy (if a skin condition is suspected) or imaging scans like a CT or MRI to check deeper tissues.
We’ll also rule out other causes like blepharitis, periorbital oedema, or other eye conditions. Learn more about macular oedema.
Once we’ve found the cause, we’ll talk you through the best way to treat it, whether that’s a home remedy, allergy care or specialist support.

Not usually. Puffy eyes are often caused by tiredness, allergies, or fluid retention. In rare cases, they can be linked to liver or kidney problems, especially if you have swelling in other parts of your body too. If you're worried, speak to your GP.
It might surprise you, but the answer is, yes, sometimes. When you’re dehydrated, your body can hold onto water in odd places, including under your eyes. Drinking more water may help reduce eye puffiness.
Bags under your eyes are usually caused by ageing, fluid build‑up, or genetics. As we get older, the tissue around the eyes weakens, and fat can shift downward, making the puffiness more noticeable.
If your eyes are puffy and you’re also feeling tired, it might be due to lack of sleep, eye strain, allergies, or even crying. All of these things can cause puffiness under the eyes and make your whole face look more tired.
Yes, most of the time. If your puffiness is caused by tiredness, crying or allergies, it usually goes away on its own with rest, hydration and cooling treatments. Persistent puffy eyes might need longer‑term changes or medical support.
There’s no one‑size‑fits‑all fix. Cold compresses, sleeping slightly raised, drinking water and cutting back on salt or alcohol can help. If puffiness is caused by allergies, antihistamines might be useful. See more tips in our puffy eyes remedy section.
It depends on what’s causing it. Eye puffiness from crying or tiredness might settle in a few hours. Swelling from allergies or conditions like blepharitis can last longer and may need treatment.
If the swelling sticks around, it could be due to age, genetics, or a condition like chalazion or blepharitis.
Yes, a gentle massage around the eye area might help shift fluid. Just be careful not to rub or press too hard, as the skin around your eyes is very delicate.
As we age, skin becomes looser, and muscles weaken. Fat can move around the eyes, and fluid doesn’t drain as well overnight. That’s why puffiness and eye bags often become more noticeable in your 30s and 40s.
