Though uneven eyelids may be caused by normal facial asymmetry, there are some medical conditions that may cause your eyelids to droop or appear uneven.
Ptosis
Ptosis, or droopy eyelid, is a condition that can affect one or both eyes. It can be present at birth (congenital ptosis) or develop later in life (acquired ptosis). Ptosis can range in severity and cause the upper eyelids to droop low enough that they reduce or block vision.

Ptosis can affect anyone, but it’s more common in older adults. Stretching of the levator muscle, which holds up the eyelid, is a common part of aging. Sometimes the muscle can separate completely from the eyelid. Ptosis can also be caused by trauma or be a side effect of eye surgery. Neurological conditions, stroke, and tumors can also cause ptosis.
Uneven fat distribution in the eyelids
Anyone can have uneven fat distribution in the eyelids, though it becomes more common as we age. Over the years, your eyelids stretch and the muscles that support them weaken. This can result in excess fat accumulating above and below your eyelids.
Tics
Tics are sudden, brief repetitive movements (motor tics) or sounds (vocal tics). Motor tics can cause blinking or grimacing the face. One side may be more active than the other, which may give the appearance of uneven eyelids. Tics are more common in children and adolescents. Most tics disappear on their own.

The cause of tic disorders is unknown, but they often run in families. Sometimes tics develop because of another condition or infection. Stress and fatigue appears to worsen tics.
Bell’s palsy
Bell’s palsy is temporary facial paralysis that affects more than 40,000 Americans each year. It results from damage or trauma to the facial nerves that are responsible for facial expressions and movements such as opening and closing the eyes, and blinking. Bell’s palsy interrupts these signals, which leads to one-sided facial weakness or paralysis.
Symptoms of Bell’s palsy include:
- drooping of an eyelid and corner of the mouth
- excessive tearing in one eye
- drooling
- excessive eye or mouth dryness
Recovery time can vary, but most people start to get better within two weeks after the onset of symptoms and recover completely within three to six months.
Apraxia of lid opening
Apraxia of lid opening is the inability to open your eyes after they’ve been closed. It can affect one or both eyes and is sometimes related to an underlying neurological condition, such as Parkinson’s disease.
Some people experience sleep-induced apraxia and have trouble opening their eyes after sleeping. There is no known cause.
Stroke

A stroke is a medical emergency that requires immediate treatment. It occurs when the blood supply to part of the brain is reduced or blocked and starves brain tissue of oxygen and nutrients. Brain cells begin to die within minutes, which is why prompt treatment is crucial.
Delaying treatment greatly increases the risk of permanent brain damage and even death.
Other signs and symptoms of a stroke include:
- trouble speaking
- confusion
- loss of balance
- numbness or paralysis of the face, arm, or leg
- sudden vision problems in one or both eyes
- sudden, severe headache
Trauma or surgery complications (nerve damage)
Damage to the facial nerves following trauma or surgery can result in drooping of the eyelid, or weakness and paralysis of the muscles around the eye.
Cosmetic facial and eyelid surgery (blepharoplasty), cataract surgery, and glaucoma surgery have been shown to pose a small risk of nerve and muscle damage.
Normal facial asymmetry
Normal facial asymmetry can make it appear as if you have uneven eyelids, even though they may actually be the same shape and size. A 2014 study of people who were evaluated for cosmetic upper eyelid surgery found that most had brow or eyelid asymmetry.
