Sanpaku eyes are a feature, not a forecast. The term describes a face where the white of the eye (sclera) shows above or below the iris instead of touching the eyelid. The look has a long cultural history, a handful of famous faces attached to it, and a much smaller medical footprint than the internet suggests.
Here is what the term actually means, where it came from, and what eye doctors say when extra scleral white is worth a second look.
What Are Sanpaku Eyes?
Sanpaku is a Japanese word that means "three whites." It describes an eye where the sclera is visible on both sides of the iris and either above or below it, so three sides of white surround the colored part of the eye.1 Most people show white only on the left and right of the iris, with the upper and lower eyelids resting against it.
In Western medicine, this visible band of sclera has a clinical name: scleral show.1 It is mostly a question of eyelid position and orbital anatomy, not a diagnosis on its own.
Types of Sanpaku Eyes
There are two types of sanpaku eyes: yin sanpaku, where the white shows beneath the iris, and yang sanpaku, where the white is visible above it.
| Eye Description | Cultural Association | Medical Mapping | |
|---|---|---|---|
| Yin Sanpaku | White of the eye visible below the iris | Physical imbalance, sensitivity, intense emotions | Lower scleral show / lower eyelid retraction10 |
| Yang Sanpaku | White of the eye visible above the iris | Mental or emotional stress, aggressive tendencies | Upper scleral show / upper eyelid retraction9 |
The cultural associations come from traditional Japanese face reading and are not scientifically validated. The medical mappings are anatomical descriptions of which eyelid sits away from the iris.
The Cultural Origin of Sanpaku
The modern Western interest in sanpaku traces back to one book. In 1965, Japanese macrobiotic theorist George Ohsawa published You Are All Sanpaku, which framed visible scleral white as a sign that "a man's entire system, physical, physiological and spiritual, was out of balance" and could signal "an early and tragic end."2
In a 1963 newspaper interview, Ohsawa claimed he had foreseen danger for U.S. President John F. Kennedy, who had visible lower scleral show, months before Kennedy's assassination that same November.2,11 That single claim seeded the modern sanpaku-as-death-omen idea in Western pop culture.
The concept itself is older. Face-reading traditions across East Asia have long treated eye shape as a window into temperament or fate, but those traditions never settled on a single, testable medical claim. They are interpretive frameworks, not diagnostic systems.
Which Celebrities Have Sanpaku Eyes?
Sanpaku gained Western attention after Ohsawa's followers identified the trait in President Kennedy, and the celebrity-spotting habit stuck. Billie Eilish is a current example of yin sanpaku (white below the iris).
Other frequently named examples include:
- Princess Diana of Wales: yin sanpaku
- Michael Jackson: yin sanpaku
- Marilyn Monroe: yin sanpaku
- Takeoff (Kirsnick Khari Ball): yin sanpaku
- Elvis Presley: yin sanpaku
Does the Celebrity List Prove Anything?
No. The list is a textbook selection bias that picks only the famous people whose lives ended badly. Hundreds of millions of people have visible lower scleral white, and the vast majority live long, ordinary lives.11
No peer-reviewed research has linked scleral show to mortality, accident risk, or violent behavior.11 Cherry-picking five celebrities out of billions of faces is not evidence. It is a pattern the brain manufactures after the fact. Even several of the people Ohsawa himself flagged as sanpaku went on to live long, healthy lives, a point his original framework never accounted for.11
The fairer way to read the celebrity list is as a cultural artifact, not a medical one. It tells you what Western audiences found compelling about Ohsawa's idea, not what your eyes say about your future.
What Does Sanpaku Mean Medically?
Sanpaku itself is not a medical diagnosis. What doctors see is scleral show, and the type matters.
Lower scleral show (yin sanpaku) is the more common pattern.5 It usually reflects normal anatomy, especially in people with a negative orbital vector, where the cheekbone sits behind the front of the eye.6 It also develops with age, after eyelid surgery, or with facial nerve weakness.10
Upper scleral show (yang sanpaku) is less common and more clinically interesting. Visible white above the iris is the classic sign of upper eyelid retraction, and the most frequent cause of new upper eyelid retraction in adults is thyroid eye disease, an autoimmune condition tied to Graves' disease.7,9
When Scleral Show Points to Thyroid Eye Disease
Thyroid eye disease (TED) inflames the muscles and fat behind the eye, pushing the eyeball forward and pulling the upper lids back. The result is a wide-eyed, staring appearance with prominent upper scleral show.7
According to the National Eye Institute and EyeWiki, signs that warrant an eye exam include:7,8
- Bulging eyes (proptosis or exophthalmos)
- Eyelids pulled back so more white shows above or below the iris
- Double vision
- Dry, gritty, red, or watery eyes
- Eye pain or pressure
- Trouble closing the eyes fully
TED is most common in people with Graves' disease, but it also appears in people with normal thyroid levels or with Hashimoto's thyroiditis.7 Early evaluation matters because timely treatment limits long-term vision and cosmetic problems.7
If upper scleral show is new, asymmetric, or paired with any of those symptoms, see an ophthalmologist or an oculoplastic specialist. The exam is straightforward and rules TED in or out.
When Scleral Show Is Just Anatomy
Most cases of visible scleral white are not a sign of disease. The 1987 Mackinnon study of healthy adults found lower scleral show in a meaningful share of the normal population, with no underlying pathology.5 The 2020 Rajabi study found that orbital shape, specifically a negative orbital vector, significantly correlates with visible lower sclera in otherwise healthy eyes.6
A few common, benign causes:
- Genetics: Eye shape and orbital depth are inherited. Many families share the look across generations.
- Aging: The lower eyelid relaxes over time, exposing more sclera.10
- Facial structure: A flat or recessed midface (negative orbital vector) leaves the eyeball sitting further forward than the cheek.6
There is also a likely evolutionary upside to visible sclera. The cooperative eye hypothesis proposes that humans evolved a comparatively white sclera, unlike most other primates, to make gaze direction easier for others to read.4 A bit of visible white may simply be a feature of being human.
What Holistic Practitioners Claim
Holistic and macrobiotic practitioners following Ohsawa's framework interpret sanpaku as a signal of bodily imbalance, blaming chronic fatigue, nutritional gaps, hormonal swings, stress, poor diet, or lack of sleep.2 These are interpretive claims, not medical findings. No peer-reviewed evidence supports using visible scleral white as a diagnostic sign of any of those conditions.11 If you have fatigue, hormonal symptoms, or sleep problems, those deserve evaluation on their own. Your eye shape is not the diagnostic clue.
Do Sanpaku Eyes Need Treatment?
Visible sclera by itself does not need treatment. The question is whether the underlying eyelid position is causing symptoms or signals something else.
When treatment makes sense:
- Dry eye or exposure: Lower eyelid retraction leaves part of the cornea exposed, which causes dryness, grittiness, or exposure keratopathy. Artificial tears, lubricating ointments at night, or surgical correction help in more pronounced cases.10
- Cosmetic concern: Hyaluronic acid (HA) dermal fillers placed under the eye reduce the appearance of lower scleral show in people with cheek volume loss.3
- Thyroid eye disease: Treatment is directed at the underlying autoimmune process, with options ranging from selenium and steroids to teprotumumab and orbital decompression in severe cases.7,8
For ordinary, longstanding, symmetric sanpaku eyes with no symptoms, no treatment is needed.
When to See an Eye Doctor
Book an appointment with an ophthalmologist if you notice:
- New or recent upper scleral show, especially with bulging eyes
- Sudden change in eyelid position on one side
- Double vision, eye pain, or pressure
- Persistent dryness, redness, or trouble closing the eyes
- A family history of thyroid disease combined with new eye changes
For longstanding sanpaku eyes that have always looked the way they do, with no symptoms and no recent change, a routine eye exam is enough. Most people will get reassurance, not a diagnosis.
The takeaway: sanpaku eyes are a way faces vary, not a forecast of fate. The cultural story is interesting. The medical story is mostly anatomy. When the trait does carry a clinical signal, doctors have tools to find it and treatment to address it.
