1. Eye Allergies
Swollen eyelids are often caused by an allergic reaction to something in your environment. If this is the cause, it is usually simple to treat. If you suffer from hay fever, for example, then you’re probably already familiar with the itchy, red, sore eyes you experience when the pollen count is high. Usually, an over-the-counter allergy eye drop will do the trick, but in more severe cases, a prescription drop is necessary.
2. Conjunctivitis
This eye condition can be caused by a bacterial or viral infection, an allergic reaction to pollen or dust mites or an irritant. Some common features include redness of the whites of the eye, a discharge and sometimes crusts on the lashes after sleeping. Conjunctivitis often starts off in one eye and spreads to the other eye after a few hours.
3. Chalazion
A chalazion is a small, harmless bump that appears on the eyelid. It looks a bit like a stye, and is caused by a blocked oil gland. The swelling can be within or on the eyelid, which can often leave it feeling heavy. Chalazia will usually disappear on their own after a few months.
4. Stye
This common eye condition is usually caused by a bacterial infection. The outer part of the eyelid becomes red and swollen and sometimes tiny, raised bumps that are filled with pus appear on the affected area. Styes usually affect one eye, but it’s possible to have them on both eyes at the same time.
5. Eye Injury
When the eye is impacted by a blunt force, it compresses and retracts. This causes blood to collect underneath the damaged area. A common side effect is swelling and discoloration, usually in the form of black eyes.
6. Eyelid Edema
Is caused by excess fluid in the eyelid. In most cases eyelid edema is caused by a reaction to an allergen or something that has been applied to the eye area, like makeup wipes or eye drops.
7. Orbital cellulitis
This condition occurs when the inflammation in your sinuses spreads to the eye area. There is typically redness and swelling of your eyelid and around your eye. Orbital cellulitis is far more common in children than in adults.
8. Blepharitis
This condition usually affects both eyes and is caused when the edges of the eyelids become inflamed. Some common features include sore, itchy eyes that feel like they’re burning. Yellow crusts on the eyelashes are also common.
9. Graves’ Disease
Is an auto-immune condition that causes your eyes to become inflamed. It is due to an overactive thyroid gland producing too much thyroid hormone, which can cause one or both eyes to bulge. Graves’ disease is also known as Thyroid Eye Disease (TED). Those with this condition often develop other eye symptoms like dryness and irritation of the eyes. Also, the eye muscles can become inflamed, affecting eye movement.
10. Eye cancer
This is rarely the cause for swollen eyes, but in some instances, it can be a cause for concern when it is accompanied with other symptoms. If you have been experiencing blurred vision, loss of vision or see floaters — squiggles or spots — moving slowly in your vision field, then it may be a sign of something more serious.
