Tunnel Vision

Tunnel Vision is a lightweight, portable Windows utility designed to eliminate visual noise and help you maintain deep focus. It automatically dims your entire screen while keeping the active window in the spotlight, reducing distractions during work or gaming sessions.

The app runs without installation - just a single executable file that requires no admin rights. It sits quietly in your system tray and can be toggled instantly with a global hotkey (Ctrl+Alt+T by default).

Key features include smart focus that automatically highlights active windows, theme awareness that adapts to Windows Light and Dark modes, ultra-low resource usage with optimized rendering, built-in auto-update checker, and customizable global shortcuts for instant control.

Perfect for users who want to reduce screen clutter while coding, writing, reading, recording, or gaming. Completely free, open-source (MIT License), and portable - carry it on a USB drive or keep it in any folder without installation hassles.
