Perception Simulator
See your interface through different eyes
A Chrome extension that simulates colour blindness, cataract, tunnel vision, dyslexia, tremor, intoxication and CRT screens directly on any webpage. Test accessibility, contrast, readable text and interactive targets — all processing stays local in your browser.
I built Perception Simulator because accessibility problems are often hard to notice when you experience an interface only through your own perception. The extension lets designers and developers apply visual scenarios—colour blindness, cataract, tunnel vision, dyslexia, tremor, and more—directly to any webpage. The goal is not medical accuracy; it’s to make accessibility barriers visible and easier to discuss early in the design process.
Everything runs locally in the browser, with no account or data collection.
I’d love to hear: which accessibility scenario would be most useful in your workflow?
