ChromaShift – Eye Comfort Reading Mode by Broken Developer

ChromaShift – Ultimate Eye Comfort & Reading Mode
Overview
ChromaShift is a lightweight, privacy-first browser extension engineered to protect your eyes, eliminate digital eye strain, and elevate reading focus. Whether you are coding late at night, reviewing dense documents, or browsing your favorite articles, ChromaShift adapts your screen environment to match your circadian biology and reading ergonomics.
Built entirely with high-performance, local-first code, it delivers cinematic color overlays and typography optimizations smoothly without slowing down your browser.

🎨 Core Features & Ocular Wellness Tools
• Intelligent Warm Filters & Screen Dimming
Smoothly adjust your display's color temperature from a crisp 10,000K down to a deeply soothing 1,000K amber glow. Granularly fine-tune brightness, contrast, and saturation to match your ambient room lighting perfectly.
• Ultra-Crisp Text Protection Mode
Unlike standard screen dimmers that wash out elements, ChromaShift utilizes a high-performance GPU Multiply blend overlay. This keeps black text razor-sharp while reducing background glare, ensuring your eyes don't struggle against blurry text.
• Interactive Reading Ruler (Focus Guide)
Activate a horizontal reading overlay that seamlessly tracks your mouse cursor. This vertical guidance line helps your eyes lock onto sentences, drastically reducing tracking fatigue and assisting users with ADHD or dyslexia.
• Clean Typography Override
Instantly strip away chaotic website fonts. ChromaShift standardizes page elements into highly readable, clean sans-serif/dyslexia-friendly system fonts, optimized with an ergonomic line-height (1.65) and comfortable letter-spacing (0.04em).
• Circadian Timer Scheduler
Automate your wellness. Set standard start and end windows to let the extension naturally adapt your color profile as daylight fades, easing your body into melatonin production.
• Daltonization Color-Blind Correction
Built-in hardware-accelerated SVG color matrices offer custom correction profiles optimized specifically to assist with Protanopia, Deuteranopia, and Tritanopia.
• 20-20-20 Rule Wellness Timer
Protect your vision over the long haul. Toggle a passive timer that gently triggers a beautiful, non-obtrusive, full-screen break prompt every 20 minutes to remind you to look at something 20 feet away for 20 seconds.

🔒 Strict Privacy-First Architecture
• 100% Offline-First: ChromaShift does not track, store, or transmit your browsing history, keystrokes, or personal data.
• Zero Remote Tracking: No third-party trackers, no telemetry scripts, and no remote code execution.
• Least-Privilege Design: The extension only requests the standard browser permissions strictly necessary to safely inject local styling components into your active tab.

🚀 Technical Blueprint & Performance
• Lightweight Footprint: Consumes minimal memory and triggers idle state behavior when your tabs aren't in focus.
• Fully Cross-Platform: Engineered to perfectly accommodate Manifest V3 architectures on Google Chrome, Microsoft Edge, and Mozilla Firefox.
