  description

  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.
