Opensight — Color Vision

OpenSight applies real-time color correction across every webpage, personalized to your unique color vision
profile.

How it works:
1. Take the free color vision test at opensight-two.vercel.app
2. Copy your calibration code from the test results
3. Paste it into the extension — correction is applied instantly

Or use Manual Setup if you already know your CVD type and severity.

Features:
• GPU-accelerated SVG color filter — zero performance impact
• Correction persists across all websites and page refreshes
• Adjustable correction strength slider
• Per-site enable/disable toggle
• Keyboard shortcut (Alt+Shift+O) to toggle on/off
• Before/after preview page with Ishihara plates and color spectrum
• Supports Protanomaly (red-weak), Deuteranomaly (green-weak), and Tritanomaly (blue-weak)
• Available in English and 简体中文

Privacy:
OpenSight does not collect any personal data. Your vision profile is stored locally in your browser. The
only network request is a one-time anonymous calibration lookup when you sync your test results.

No account required. No ads. Free.
