About ClearColorVision - Advanced Color Vision Deficiency Corrections

ClearColorVision – Personalized Color Correction for the Colorblind 🧠 See the web in your true colors ClearColorVision is a Chrome extension that helps people with color blindness see websites more clearly. It changes colors in real time so that tricky color combinations (like red and green, or blue and yellow) are easier to tell apart—without making the website look weird or unnatural. ✨ What's New in the Latest Update I've completely rebuilt the color vision test from the ground up. The new test uses confusion-axis chromatic discrimination with an adaptive staircase — the same scientific method used in clinical tools like the Cambridge Colour Test and the CAD test (used by the UK Civil Aviation Authority to certify pilots). Instead of just comparing color swatches, it measures your exact discrimination threshold while masking brightness cues with noise, so the results reflect your real color vision — not just your ability to spot brightness differences. This means far more accurate severity detection and better-tuned correction personalized to your eyes. As part of this update, I've removed tritan (blue-yellow) testing to focus entirely on the accuracy of protan and deutan testing, which cover the vast majority of color vision deficiency cases. Fewer features, done properly. 🎨 How it works: ClearColorVision uses smart color correction based on how your eyes work. After a quick built-in color vision test, it creates a custom profile just for you. It then uses two advanced methods: LMS Daltonization: Keeps things looking natural by adjusting colors based on how your eyes see them. PCR (Perceptual Contrast Rebalancing): Improves text and color contrast, especially in hard-to-read areas. 🔍 Features: Fast color vision test Personalized color correction using LMS and PCR Helps you read text and see colors better One-click on/off switch Doesn’t collect any personal data—everything runs on your device 👁 Great for people with mild to moderate color blindness who want to browse the web more comfortably and confidently.
