About us
Numbers you can check
Eye Color Rarity began with a simple annoyance: sites ranking eye colors quote the same precise numbers, few say where they came from, and fewer admit what nobody knows. We built the reference we wanted to read.
What we are
- An independent reference on eye color prevalence, genetics, and identification.
- A synthesis project: we compare ophthalmology guidance, genetics research and large datasets, then publish labeled estimates.
- Open about method. The methodology page is the most important page on this site.
- Free to read, with no paywall and no account.
What we are not
- Not a medical provider. Our content is not medically reviewed, and nothing here diagnoses or treats anything. Sudden changes in eye color call for an eye doctor, not a website.
- Not a census. Our worldwide figures are estimates with ranges, because an honest range is more useful than a falsely exact number.
- Not selling contacts, supplements or anything that claims to change eye color.
Our process
How we build a page
- 01
Find the original
We trace each figure back to the study or poll it came from, instead of copying it from another list.
- 02
Set the estimate
Ranges and point estimates follow our methodology, with the same confidence grading for every color.
- 03
Flag the gaps
If we can't trace a popular claim, the page says so. Weak numbers get a low confidence label.
- 04
Update
When better data appears, we change the numbers. The 2025 license study reshaped our gray and U.S. figures.
Principles
Three rules we work by
Evidence before narrative
We start from what the literature can support, then write. If a popular claim can't be traced to a source, we leave it out or say that we couldn't trace it.
Uncertainty is content
Ranges and confidence labels sit next to our headline figures. Where the data is weak, the page says so in plain language.
Open to correction
Anyone can challenge a number through the contact page. If you show us a better source, we will update the page.
Spot something the evidence disagrees with?
Tell us what you found and what source supports it. A message that starts with “this number is wrong” is welcome here.
