See through a color-blind, cataract or glaucoma eye, live from your camera or on sample photos

Points your camera at anything and simulates 20 vision conditions in real time, including deuteranopia, migraine aura, floaters and macular degeneration, with a short explainer for each. A quick test builds your own vision profile, and everything is processed in the browser.

Notes

The live mode needs camera permission, which I could only exercise with a fake camera feed; the screenshot is the deuteranopia explainer page on sample photos. Maker's other projects are Claude-related but neither the page nor his HN post says how howisee was built, so AI use is unconfirmed.
