Blink 20 👁️

Protect your vision with the scientifically-backed 20-20-20 rule.

Blink 20 is a sleek, intelligent eye-care assistant for VS Code tailored for developers who spend hours coding. It seamlessly integrates into your workflow to prevent digital eye strain without breaking your concentration.

What is the 20-20-20 Rule?

The American Optometric Association recommends:

Every 20 minutes, take a 20-second break and focus your eyes on something 20 feet (6 meters) away.

This simple habit relaxes the focusing muscles inside the eye, reducing fatigue and preventing long-term damage.

Features

⏱️ Smart Focus Timer

• Automatic Tracking: The timer starts when you open VS Code.
• Continuous Mode: Moving focus to another window does not stop the timer (short switching is considered work).
• Smart Reset: If you leave VS Code for more than 5 minutes, the timer resets, assuming you've taken a break.
• Multi-Window Sync: The timer state is synchronized across all open VS Code windows.
• State Persistence: The timer state is saved, so restarting VS Code won't reset your progress.

🔔 Gentle yet Effective Reminders

• Status Bar Integration: A discreet 👁️ MM:SS countdown keeps you informed.
• Focus Mode: When it's time to rest, a modal dialog gently interrupts your workflow.
• Enforced Rest: A 20-second progress bar guides you through the break.

🌍 Localization / 多语言支持

• English: Fully localized interface.
• Chinese (简体中文): 完美支持中文界面，符合中文用户习惯。

Usage

1. Install: Search for "Blink 20" in the VS Code Marketplace and install.
2. Code: Just start coding! The timer runs automatically.
3. Rest: When the notification appears:
   • Click "Start Rest" (or "开始休息").
   • Look away from your screen for 20 seconds.
