Waking up with puffy or swollen eyes can be uncomfortable and worrying. The swelling may happen in one eye or both eyes. It may also come with itching, redness, watering, pain or a heavy feeling around the eyelids.
There are many swollen eyes causes and not all of them are serious. Sometimes the reason is as simple as lack of sleep or an allergy. In other cases, an infection or another eye problem may need medical care. Knowing the common reasons can help you understand when simple care may be enough and when it is better to see an eye doctor.
7 Common swollen eyes causes and When to See a Doctor
1. Allergies
Allergies are one of the most common swollen eyes causes. Dust, pollen, pet hair, smoke, makeup or some skin products can irritate the eyes. When your body reacts to an allergen the eyelids may become puffy, itchy and watery.
The swelling is often seen in both eyes. You may also have sneezing or a blocked nose.
Try not to rub your eyes because rubbing can make the irritation worse. A clean cold compress and staying away from the trigger may help. If the problem keeps returning, speak with an eye doctor.
2. Lack of Sleep
A late night can easily show up on your face the next morning. Not getting enough rest may cause fluid to collect around the eyes, making the eyelids look puffy.
Among everyday swollen eyes causes, poor sleep is usually easy to notice. The eyes may feel tired or heavy but there is often no strong pain or discharge.
Try to follow a regular sleep routine and avoid screens too late at night. Keeping your head slightly raised while sleeping may also help reduce morning puffiness.
3. Eye Infection
Eye infections can also lead to swelling. Conjunctivitis, often called pink eye, may cause redness, watering, itching or sticky discharge. Some infections can spread from one eye to the other.
Infections are important swollen eyes causes because they may need proper treatment. Avoid sharing towels, pillows, eye makeup or contact lenses if you think you have an infection.
Wash your hands often and avoid touching your eyes. If there is pain, heavy discharge, blurred vision or worsening swelling, get your eyes checked.
4. Stye or Blocked Oil Gland
A stye is a small, painful lump that can form near the edge of the eyelid. It usually happens when an oil gland or hair follicle becomes blocked or infected.
This is one of the swollen eyes causes that may affect only a small part of the eyelid. The area can look red, tender and swollen.
A warm compress may help the blocked gland open naturally. Do not squeeze or pop the lump. If it becomes very painful or does not improve, an eye doctor should examine it.
5. Too Much Salt or Fluid Retention
Eating very salty food can sometimes make the area around your eyes look puffy the next morning. Salt can make the body hold extra water and the skin around the eyes is thin.
This type of swelling is usually mild and may improve during the day. Drinking enough water and reducing very salty foods can help.
If eye puffiness keeps happening without a clear reason or appears with swelling in other parts of the body, it is better to speak with a doctor.
6. Crying for a Long Time
Crying can cause temporary swelling around the eyes. Tears and increased blood flow around the eyelids may leave the area looking puffy for some time.
It is one of the more harmless swollen eyes causes and usually settles on its own. A clean cold compress can feel soothing. Drinking water and resting may also help.
Try not to rub the eyes after crying, as this can make redness and swelling worse.
7. Eye Injury or Irritation
A small injury, dust particle, chemical splash, insect bite or reaction to a cosmetic product may lead to eye swelling.
These swollen eyes causes need more attention because the right response depends on what caused the irritation. If dust enters the eye, rinsing gently with clean water may help. If a chemical gets into the eye, rinse it immediately with plenty of clean water and seek medical care.
Do not use random eye drops or home remedies after an injury. If you have strong pain, trouble seeing, bleeding or fast growing swelling, get medical help quickly.
