What you can and cannot change about eye color
Your natural eye color is determined by the amount and type of melanin in your iris — the colored part of your eye — and that does not change on its own after you are born. Once your eye color is set, usually by age three, it stays that way for life. You cannot permanently alter your eye color through diet, supplements, or willpower.
However, you can temporarily change how your eyes appear using contact lenses, and in rare cases a surgeon can perform a procedure to alter eye color permanently. The temporary routes are safe and reversible. The permanent surgical route carries real risks and is not widely available.
Key Takeaways
- Contact lenses are the safest and most affordable way to change eye color, and you can switch back whenever you want.
- Colored contact lenses require a valid prescription from an eye doctor, even if you do not need vision correction.
- Surgical eye color change exists but is rare, expensive, and carries risks including vision loss and infection.
- Some natural changes in eye color can happen due to aging, illness, or medication, but these are not changes you control.
- Certain lighting, clothing, and makeup can make your existing eye color appear different without any product or procedure.
Colored contact lenses: the practical option
Colored contacts are the most common way people change their eye appearance. They come in opaque (solid color that covers your iris completely) and enhancement (tinted to deepen your existing color) styles. Opaque lenses work on any eye color and can make brown eyes blue, green eyes brown, or any other shift. Enhancement tints work best if you already have light-colored eyes.
You will need a prescription from an eye doctor to buy colored contacts, even if you have perfect vision and do not wear glasses. The prescription includes your lens power (which may be zero if you need no vision correction), the curve of your eye, and the lens diameter. Without this information, contacts will not fit properly and can scratch your cornea.
Colored contacts cost between $30 and $150 per pair, depending on the brand and whether they correct vision. A box typically contains six lenses (three pairs), so one box lasts three months if you wear them daily. You can find them at optical shops, online retailers, and some drugstores, but you must provide a valid prescription.
The main drawback is maintenance. You need to clean and store them in solution every night, replace them on schedule (usually monthly or quarterly), and never sleep in them unless the box says they are overnight-safe. Overwearing contacts or poor hygiene can lead to eye infections.
Surgical eye color change: rare and risky
A few surgeons worldwide perform procedures to permanently change eye color by implanting a colored lens or using a laser to remove melanin from the iris. The most common procedure is implantation of a colored intraocular lens, similar to the lens used in cataract surgery.
These surgeries are expensive — typically $5,000 to $15,000 per eye — and are not covered by insurance because they are elective. They are also not approved by the U.S. Food and Drug Administration for cosmetic use, which means the procedure is not regulated the way surgical treatments are. Surgeons performing this work are usually operating in countries with less stringent oversight.
The risks are serious. Complications include infection, inflammation inside the eye, glaucoma, cataracts, and vision loss. Some people report halos around lights or difficulty seeing in low light after the procedure. Because the surgery is irreversible, any complication is permanent.
If you are considering surgical eye color change, understand that you are accepting the risk of blindness in that eye. Consult an ophthalmologist (not just an optometrist) who can explain the specific risks of the surgeon and facility you are considering.
Why your eye color might change naturally
Eye color can shift slightly over time due to aging, illness, or medication — but these are changes that happen to you, not changes you make. Babies are often born with blue or gray eyes because melanin has not yet accumulated in the iris. Over the first year of life, melanin increases and the eyes darken to their permanent color.
In adulthood, eye color can lighten slightly with age as the iris loses pigment. Certain medications, including some glaucoma treatments and antimalarial drugs, can darken the iris over time. Conditions like Horner syndrome or heterochromia (two different colored eyes) can also affect eye color, but these are medical conditions, not cosmetic changes.
Lighting and your surroundings also affect how your eye color appears. Blue and green eyes look more saturated in bright daylight and can appear gray or dull indoors. Wearing colors that complement your eyes — blues and purples for blue eyes, oranges and reds for brown eyes — can make them appear more vivid.
Makeup and styling tricks that enhance eye color
If you want your eyes to appear a different color without contacts or surgery, makeup and clothing choices can create that effect. Eyeshadow in contrasting colors makes your eye color pop: warm bronze and copper shades enhance blue eyes, while cool silvers and purples make brown eyes appear warmer and richer.
Eyeliner also plays a role. A dark eyeliner makes light eyes appear lighter by contrast, while a white or nude eyeliner on the waterline (the inner rim of your lower lid) can make your eyes look larger and brighter. Mascara darkens your lashes and makes your eyes more prominent overall.
Your clothing color influences how your eyes appear too. Wearing colors that match your eyes makes them blend in, while wearing complementary colors makes them stand out. If you have green eyes, wearing red or burgundy makes them appear more vivid. If you have brown eyes, wearing blue or teal creates contrast.
Frequently Asked Questions
Do colored contact lenses work on dark brown eyes?
Yes, but only opaque lenses work well on very dark eyes. Enhancement tints are too light to show up on brown eyes. Opaque colored contacts completely cover your iris and can make brown eyes appear blue, green, hazel, or any other color. You still need a prescription from an eye doctor.
Can you wear colored contacts if you have astigmatism?
Yes. Toric contact lenses are designed for astigmatism and come in colored versions. They cost more than standard colored contacts because they must be oriented correctly on your eye. Your eye doctor can fit you for toric colored lenses if you have astigmatism.
What happens if you wear colored contacts without a prescription?
Contacts that do not fit your eye properly can scratch your cornea, cause pain, and lead to infection. Even if they feel fine at first, an ill-fitting lens can damage your eye over time. You need a valid prescription to may support the lens curve and diameter match your eye.
Is laser eye color change surgery safe?
Laser procedures to remove melanin from the iris are not approved by the FDA for cosmetic use and carry significant risks, including permanent vision loss, glaucoma, and chronic eye pain. The procedure is not widely available in the United States. If you are considering it, consult an ophthalmologist about the specific risks.
Can you change eye color permanently without surgery?
No. Contacts are temporary and reversible. Dietary supplements, eye drops, and other non-surgical products cannot permanently change eye color, despite claims some make online. The only permanent method is surgery, which carries serious risks.
