HueLens: Color Blind Test

HueLens is a color-vision self-test built for the way red-green color vision deficiency actually works — three axes, not one rigid type.

Take a daily Ishihara-style plate test in about two minutes. Answer what you see, and HueLens scores it, charts your result over months, and lets you export a clean summary to bring to an eye doctor. When you are not sure, "I don't see a number" is always an honest answer — no shame.

- A daily plate-style color vision test, procedurally drawn so it is fresh every time
- A three-axis severity slider tunes protan, deutan and tritan together, not one rigid type
- A live preview shows the same swatches the way full-color vision sees them, right next to your eyes
- Charts your result over months so you can watch it change over time
- Export a clean CSV summary you can bring to an eye doctor
- Everything runs on your iPhone — nothing is uploaded anywhere

Built as an everyday accessibility aid and a personal self-screening tool. It does not diagnose color vision deficiency and is not a substitute for a professional eye exam.
