Uneven Eyes: What Causes Asymmetrical Eyes And 4 Ways To Fix Them Naturally

Asymmetrical eyes — often called “uneven eyes” — are a concern for many, and not just for cosmetic reasons. In more serious cases, uneven eyes can narrow your visual field and even affect your vision. People with noticeable asymmetry may also feel self-conscious or struggle with confidence issues.

There are many possible causes behind uneven eyes, ranging from natural to medical. And before you can fix the issue, you need to understand why it’s happening in the first place. In this blog, we’re breaking down the key causes of uneven eyes, the types of asymmetry, and 4 practical ways to improve the condition — including one unexpected solution that might surprise you!

What Exactly Are Uneven Eyes?

The medical term for this condition is ptosis, which refers to a drooping upper eyelid that makes one eye look smaller than the other. That droop causes the eyes to appear lopsided or asymmetrical.

Here’s the thing: nobody’s face is perfectly symmetrical. Almost everyone has some degree of imbalance between the two sides — and that includes the eyes. In fact, up to two-thirds of people have slight unevenness in their eye shape or size. The real issue comes when the imbalance is noticeable or begins to worsen over time due to age, screen usage, or other lifestyle factors.

From a clinical perspective, doctors don’t just look at which eye looks "bigger." A more accurate test is to observe the distance between the base of your eyelashes and the center of your pupil when your eyes are open normally. Ideally, your upper eyelid should only cover about 1mm of the upper part of your pupil. If it's covering 2–3mm or more, the eye can appear tired, dull, or droopy — classic signs of ptosis. Eye doctors use this measurement to determine whether you actually have uneven eyes and how severe the condition might be.

Common Non-Medical Causes of Uneven Eyes

i. Genetics

Just like you inherit your eye color, you can also inherit uneven eyelids. If family members have a noticeable asymmetry, chances are higher that you might, too. Some people are born with weak or underdeveloped levator muscles (the muscles that lift your eyelids), which makes it harder for one eye to open fully. Others naturally have excess fat in the upper eyelid, making one eye appear puffier or smaller.

ii. Aging

Your eyes may have been perfectly symmetrical in your youth — but as time goes by, that can change. With age, we lose collagen and muscle strength, especially in the delicate eye area. The eyelids can start to sag, making one eye appear smaller than the other. In some cases, fat tissue around the eyes may shift or droop as well, putting extra strain on the muscles and worsening the asymmetry.

iii. Wearing Contact Lenses or Circle Lenses

Frequent use of contact lenses — including cosmetic lenses like circle lenses or colored contacts — can put stress on the eyelids. Pulling and stretching the skin while inserting or removing lenses can weaken the skin’s elasticity over time, leading to sagging. Also, because contacts reduce oxygen flow to the eyes, prolonged wear can make your eyes tired, which may contribute to a droopy eyelid.

iv. Prolonged Screen Time

Modern life means we’re glued to screens — phones, laptops, tablets — all day long. The blue light from these devices can dry out and irritate your eyes. If you constantly rub your eyes due to dryness or fatigue, the delicate eyelid skin can lose elasticity, increasing your chances of developing uneven eyelids.

v. Heavy or Frequent Eye Makeup

Many of us rely on makeup to enhance or balance out our eye shape. But over time, applying eyeliner, false lashes, or eyelid tape can put stress on the skin and muscles. Wearing and especially removing eye makeup (especially if you rub aggressively) can cause the eyelids to sag. Leaving residue on the eyes by not cleansing thoroughly can also cause inflammation and, in some cases, even styes.

Medical Causes of Uneven Eyes

i. Eyelid Muscle Weakness (Ptosis)

Ptosis can be caused by nerve damage, weak muscles, or issues with the eyelid’s connective tissue. If the nerve pathways that control the eyelid are disrupted — due to congenital defects or other health issues — the muscle can't function properly, resulting in drooping.

ii. Myasthenia Gravis (MG)

This autoimmune condition disrupts the communication between nerves and muscles, leading to fatigue and weakness. One of the first visible symptoms is eyelid drooping. Many patients notice the ptosis is worse at night compared to the morning, as the muscle weakens with use throughout the day.

iii. Thyroid Eye Disease

If left untreated, thyroid issues — especially hyperthyroidism — can spread to the eye area. This can cause dryness, swelling, eye bags, sensitivity to light, and asymmetry, including uneven or bulging eyes.

iv. Stroke (Cerebral Vascular Accident)

Sudden changes in eye symmetry, especially if accompanied by vision problems, drooping eyelids, or changes in facial expression, could be early signs of a stroke. A stroke can affect nerves or blood vessels that control the eyes, often causing one-sided ptosis.

How to Fix Uneven Eyes: 4 Natural Remedies

i. Give Your Eyes a Break

Too much screen time leads to eye fatigue — one of the biggest causes of eyelid sagging. The 20-20-20 rule is a lifesaver: every 20 minutes, look at something 20 feet away for at least 20 seconds. This helps relax your eye muscles and reduce stress on your eyelids.

ii. Avoid Rubbing Your Eyes

Rubbing your eyes stretches the skin, damages elasticity, and increases fine lines. If your eyes feel itchy or irritated, resist the urge to rub. Instead, apply a cold compress or use an eye mask to calm the area.

iii. Try Warm Compresses or Eye Masks

A warm towel placed over your closed eyes for 10–15 minutes can improve blood circulation, ease tension, and relieve eye fatigue. Just make sure the towel isn’t hotter than 40°C to avoid burns. Eye masks with nourishing ingredients can also help firm up the delicate skin and slow down sagging.

iv. Do Eye Exercises or Massage

Gentle massage can relax tired muscles and support better circulation. Try these simple techniques:

• Eyeball Pressure Massage: Close your eyes and gently press your fingertips on your eyelids for 20 seconds. Use small circular motions but be careful not to apply too much pressure.
• Forehead Sweep: Place your index, middle, and ring fingers on your forehead and sweep outward toward your temples while gently massaging the skin.
• Brow Pinch: Use your thumbs to press gently at the inner corners of your eyebrows and hold for 10 seconds. This helps relax tension in the upper face and brow area.

What Kinds of Surgery Can Permanently Correct Uneven Eyes?

i. Double Eyelid Surgery (Blepharoplasty)

One of the most common reasons for uneven eyes is ptosis (droopy eyelids), usually affecting just one side. That’s why many people opt for double eyelid surgery to correct the imbalance. This procedure is also suitable for those with weak eyelid muscles, excessive fat in the upper eyelid, or naturally thick eyelid skin.

A trained plastic or ophthalmic surgeon will typically make an incision along the eyelid crease to remove excess skin, fat, and orbicularis oculi muscle tissue. Then, the sagging eyelid is lifted and reattached at a higher position, restoring symmetry and enhancing eye proportions. This can effectively resolve the appearance of uneven eyes.

That said, be aware of the potential downsides. Swelling after surgery is common — often more noticeable in the morning. The recovery period can also be lengthy and may include symptoms like eye pain, bruising, swelling, dryness, or even temporary blurred vision.

ii. Eyelid Muscle (Levator) Surgery

This is another go-to option for treating uneven eyes, especially in cases caused by drooping eyelids or muscle weakness. Levator surgery is a minimally invasive procedure where the surgeon works from behind the eyelid, carefully exposing the levator muscle and tarsal plate (the cartilage structure in your eyelid). They then stitch the tarsal plate to a higher point on the levator muscle to elevate the eyelid.

The result? Both eyes regain a more balanced, symmetrical look — making this a highly effective solution for many ptosis cases.

iii. Botox Injections

Botulinum toxin (Botox) is a neurotoxin that temporarily blocks nerve signals to specific muscles. In cosmetic use, this helps lift sagging skin and smooth fine lines by relaxing overactive muscles. In the context of uneven eyes, Botox can provide a lifting effect and help adjust eye symmetry.

However, it comes with some caveats. Because Botox works by interfering with nerve activity, muscle weakness can sometimes occur, which may lead to a stiff or unnatural expression. Improper technique or incorrect dosage could also make the asymmetry worse rather than better — causing uneven eyelid shapes or inconsistent eye size.

iv. Thread Lifting

Thread lifts are generally better suited for people with thin eyelid skin, minimal fat around the eyes, and no severe skin laxity. This non-surgical method involves making tiny punctures in the eyelid and inserting fine threads to lift and tighten the skin. These threads help reshape the eyelid fold and restore symmetry between both eyes.

Since no incisions are made, the recovery time is shorter — most people see the swelling subside within two weeks. However, thread lifts aren't permanent. The results typically last 3 to 5 years, after which the threads may loosen or break down gradually.
