ChromaShift – Eye Comfort Reading Mode

About

ChromaShift is a dedicated visual comfort and reading companion designed to reduce digital eye strain during long browsing sessions. The extension operates as an all-in-one visual health utility to protect your eyes, improve reading focus, and optimize your sleep cycle.

Core Ocular Wellness Features:
• Custom Warm Filters: Smoothly adjust color temperature (from a cool 10000K to a deeply warming 1000K), brightness, contrast, and saturation.
• Ultra-Crisp Mode: Leverages a high-performance GPU Multiply blend overlay to protect and sharpen black text, eliminating the fuzzy text side-effect of standard screen dimmers.
• Reading Ruler focus guide: A horizontal guiding track follows your cursor as you read, significantly reducing optical fatigue and aiding tracking focus.
• Clean Typography override: Standardizes page fonts to clean sans-serif/dyslexia-friendly system fonts and optimizes line-spacing and letter-spacing on complex webpages.
• Circadian Timer scheduler: Easily set custom start and end schedules to automatically active your warm filters when evening falls.
• Daltonization color correction: Built-in color-correction matrices designed to assist with Protanopia, Deuteranopia, and Tritanopia.
• 20-20-20 Rule break timer: Optional passive timer reminds you to rest your eyes every 20 minutes with a gentle, non-obtrusive overlay prompt.

Privacy and Efficiency First:
ChromaShift is built from the ground up to be ultra-lightweight and local-first. The extension does not collect, record, or transmit any web activity, domain URLs, or personal data.
