How it works
BlyndSyde uses an optical trick: deep red lenses make your screen readable to you, but to anyone else it's colorful chaos

This is what it's like to use BlyndSyde
Heads up — only deep red lenses work. Amber, yellow or other colors and even lighter red lenses won't work (we've tried them!) See our tested list →. DRM-protected and true fullscreen windows cannot be BlyndSyded (use Zoom or Fill mode). Screen Recording permission required. Nothing leaves your computer. No analytics. No telemetry. No tracking. No login.
