What Is a Scleral Tattoo?
A scleral tattoo involves injecting colored ink under the conjunctiva (the thin, clear membrane covering the white part of the eye) to change the color of the visible sclera. The procedure was not developed by a medical professional, has no standardized technique, and has never undergone formal medical study for safety, according to the AAO. No training program or certification exists for people who perform this procedure.
The person performing the injection uses a needle to place ink between the conjunctiva and the sclera. There is no way to control how the ink spreads once it enters this space. The ink is permanent and cannot be fully removed.
Some people seek scleral tattoos as a form of body modification or self-expression. Social media posts showing dramatic color changes in the white of the eye generate interest, but these posts rarely show the complications that can follow. The striking visual result can look appealing in a photo while hiding the serious risks involved.
Unlike skin tattoos performed by licensed professionals using regulated equipment, scleral tattoos have no safety standards, no regulated ink formulations designed for ocular use, and no oversight from any medical or licensing body.
There is no established safe technique for scleral tattooing. Even experienced eye surgeons who inject medications into the eye use precise instruments, sterile operating conditions, and drugs tested for intraocular safety. Scleral tattooing uses none of these safeguards. The inks used are typically skin tattoo inks that were never designed to contact the inside of the eye.
The AAO has issued clear warnings against this procedure. Eye care organizations worldwide have spoken against it due to the high rate of severe complications.
Documented Complications
The needle used for scleral tattooing can puncture through the wall of the eye and inject ink directly into the interior. A 2019 literature review published in the Canadian Journal of Ophthalmology found that 10 of 14 reported cases (71%) were complicated by inadvertent globe puncture with intraocular ink injection. Once ink enters the inside of the eye, it can damage the retina, lens, and other structures.
The sclera varies in thickness across different parts of the eye, and the person performing the tattoo has no way to gauge depth with precision. Even a slight miscalculation sends the needle through the eye wall.
Decreased vision and permanent blindness are among the most devastating outcomes. The AAO and a 2024 PMC review list vision loss as a known complication of scleral tattooing. Ink inside the eye can coat the retina and block light from reaching the photoreceptor cells. Chronic inflammation from the ink can damage the optic nerve over time.
Some patients experience gradual vision decline over months as ongoing inflammation takes its toll. Others lose significant vision immediately if the needle damages internal structures during the injection.
Endophthalmitis (a severe infection inside the eye) can develop when bacteria enter the eye during the injection. This condition causes intense pain, swelling, and vision loss that progresses over hours. Without emergency treatment, endophthalmitis can destroy the eye.
Even without infection, the ink itself triggers chronic inflammation. Uveitis (inflammation of the middle layer of the eye) and scleritis (inflammation of the sclera) can persist for months or years. Patients may need long-term anti-inflammatory medications, and some never achieve complete control of the inflammation.
Chronic inflammation inside the eye can lead to secondary glaucoma (elevated eye pressure that damages the optic nerve). The drainage system of the eye becomes clogged by inflammatory cells and ink particles, causing pressure to build. If not controlled, glaucoma causes progressive, permanent peripheral vision loss.
Retinal detachment can occur when ink or scar tissue pulls on the retina or when a needle puncture creates a hole in the retinal wall. Both complications require surgical intervention and may still result in permanent vision loss despite treatment.
In the most extreme cases, the damage is so severe that the eye must be surgically removed. The AAO and PMC both list enucleation as a reported outcome of scleral tattooing. When infections become uncontrollable, when chronic pain is unmanageable, or when the eye poses a risk to the other eye through sympathetic inflammation, removal may be the only option left.
Losing an eye permanently changes a person's depth perception, peripheral vision, and appearance. It requires a prosthetic eye and lifelong follow-up care.
A 2025 case report published in Cornea described a patient with bilateral scleral tattoos (both eyes) who developed corneal dellen (thinning and drying of the cornea near an elevated area) and subconjunctival granulomas (firm nodules of inflamed tissue under the conjunctiva). The patient required surgery to remove the granulomas and repair the corneal damage.
These granulomas form as the body's immune system reacts to the foreign ink particles trapped under the conjunctiva. They can grow, become painful, and distort the surface of the eye.
Hidden Long-Term Dangers
The permanent dye changes the appearance of the sclera and conjunctiva in ways that interfere with future medical evaluations. The AAO and Ophthalmology Times have noted that scleral tattoos hinder the detection of several conditions:
- Conjunctival melanoma (cancer of the membrane covering the white of the eye), which appears as a pigmented spot that doctors monitor for changes
- Scleral icterus (yellowing of the whites of the eyes), an early sign of liver disease, hepatitis, or other systemic illness
- Scleritis (inflammation of the sclera), which causes redness and discoloration that the tattoo hides
- Scleral thinning, which can signal autoimmune disease or other serious conditions
Once injected, the ink spreads under the conjunctiva in unpredictable patterns. It can migrate to areas far from the injection site, creating an uneven or blotchy appearance. The ink cannot be laser-removed like a skin tattoo because the eye's delicate structures cannot tolerate the energy levels required.
Over time, some inks change color or fade unevenly. What begins as a desired shade may shift to a muddy or patchy look that no further injection can correct.
There is no reliable method to remove scleral tattoo ink. Surgical excision of the stained conjunctiva is possible in some cases, but it cannot remove ink that has soaked into the scleral tissue. The procedure leaves scars, and the cosmetic result after removal surgery is often poor. Some patients require multiple surgeries and still cannot fully restore the eye's natural appearance.
Once the ink is in your eye, you will deal with its consequences for the rest of your life.
Legal Status of Scleral Tattoos
Several jurisdictions have passed laws banning scleral tattooing due to the severe risk of harm. The procedure is banned in Oklahoma, Indiana, Washington State, and Nebraska. In Canada, Ontario and Saskatchewan have made the procedure illegal.
These laws reflect a growing awareness among lawmakers and medical professionals that scleral tattooing poses unacceptable risks. Other states and countries are considering similar legislation.
In places where scleral tattoos are not banned, the procedure exists in a regulatory gray area. No medical board oversees the practitioners. No health department inspects the facilities. No governing body tests the inks for safety. Patients have little legal recourse when complications arise because the procedure falls outside standard medical or cosmetic practice.
The lack of regulation does not mean the procedure is safe. It means that no authority has yet acted to prohibit it in that area.
The American Academy of Ophthalmology warns against scleral tattooing in clear terms. Ophthalmology organizations in multiple countries have issued similar advisories. These groups represent thousands of eye surgeons who have seen the damage firsthand and who agree that no cosmetic benefit justifies the risk of blindness, chronic pain, or loss of the eye.
No reputable eye care professional performs or endorses scleral tattooing.
Questions About Scleral Tattoo Safety
No. Even highly skilled skin tattoo artists lack the training, instruments, and medical knowledge needed to safely inject material around the eye. The anatomy of the eye is far more delicate than skin, and the consequences of error are far more severe. The high rate of globe puncture documented in medical literature shows that no amount of tattoo experience makes this procedure safe.
See an ophthalmologist as soon as possible. Symptoms like increasing pain, redness, light sensitivity, worsening vision, or a growing bump on the eye surface all require professional evaluation. Early treatment of complications like infection and inflammation can help limit the damage, even if it cannot undo the tattoo itself.
Colored contact lenses prescribed and fitted by an eye doctor are the safest way to change the appearance of your eye color. These lenses are FDA-regulated, tested for safety, and available in many colors. Never buy colored contacts without a valid prescription, as poorly fitting lenses can cause corneal ulcers and infections.
No. Laser tattoo removal techniques used on skin cannot be safely applied to the eye. The energy levels needed to break down ink particles would damage the sclera, conjunctiva, and internal eye structures. Surgical excision of stained tissue is sometimes attempted, but it cannot remove all the ink and often results in scarring.
Published medical case series show extremely high complication rates. The Canadian Journal of Ophthalmology review found globe puncture in 71% of reported cases. Virtually every published case series documents multiple serious complications. Because there is no registry or reporting requirement, the true complication rate may be even higher than what appears in medical literature.
Legislation takes time. Scleral tattooing is a relatively new phenomenon, and many lawmakers are still learning about its risks. Medical organizations are actively advocating for broader bans. The states and provinces that have already acted did so after reviewing the medical evidence and hearing from patients harmed by the procedure.
Protect Your Eyes and Your Future
No cosmetic change is worth risking your eyesight. Scleral tattoos carry documented risks of blindness, chronic pain, infection, and loss of the eye. If you are considering changing your eye appearance, talk to a licensed eye care professional about safe options like prescription colored contact lenses. If you already have a scleral tattoo and are experiencing any symptoms, schedule an appointment with an ophthalmologist for a thorough evaluation.
