About this app
Protect your vision, reduce eye strain, and sleep better with Lumen Guard.
Is your phone screen too bright, even at the lowest setting? Do you experience eye fatigue or trouble sleeping after late-night scrolling?
Lumen Guard is a professional screen dimmer and blue light filter designed to protect your eyes from harsh display lighting. By applying a scientifically tuned overlay, it allows you to dim your screen well below the system's default minimum, reducing headaches and helping you maintain a natural circadian rhythm.
Whether you are reading in bed, using your phone in a dark theater, or simply sensitive to bright screens, this app gives you complete, continuous control over your display.
🌟 Key Features
Advanced Screen Dimmer: Override your system's brightness limits. Dim your screen to extremely low levels for comfortable, glare-free use in pitch-black environments.
Precise Blue Light Filter: Block harmful blue light that keeps you awake. Fine-tune your screen's color temperature with continuous, precise Kelvin controls to soothe your eyes and fall asleep faster.
Migraine Relief (Calm Green): An exclusive 530nm-inspired green-enriched screen profile specifically designed to reduce visual stress for users with migraine sensitivity.
Interactive Floating Widget: Adjust brightness, tweak your filter profile, or quickly pause the app directly from your home screen without ever interrupting your workflow.
Custom Scenes & Profiles: Save your favorite settings for different environments. Use built-in, calibrated presets like "Reading," "Theatre," "Late Night," or "Office," or create your own custom scenes.
Smart Scheduling: Set it and forget it. Automatically turn on your eye-protection filters at sunset or during your scheduled bedtime hours to ensure your eyes are always protected.
Battery Efficient: Engineered for performance, Lumen Guard uses minimal battery and is lightweight on system resources, utilizing hardware-floor optimizations for OLED and LCD screens.
🔒 Privacy & Permissions
We believe in total transparency. Lumen Guard is completely secure and requires only the standard system permission to function:
Display Over Other Apps: Required to draw the protective dimming and color filters across your screen. No user data, screen content, or personal information is ever collected, stored, or read.
💎 Premium Features
Upgrade to Lumen Guard Premium for the ultimate lifetime experience:
Ads-free, uninterrupted usage.
Unlimited custom scenes.
Unlimited automated daily schedules.
Always-available floating widget controls.
Priority developer support.
