Vision Aid: Accessibility for Color Blindness & Low Vision

About

Vision Aid is a comprehensive accessibility extension that makes the web more accessible for users with color vision deficiencies (color blindness, daltonism) and low vision conditions. Unlike basic color filters, Vision Aid uses clinically-researched color correction matrices and intelligent enhancement algorithms to provide accurate, comfortable color adjustments that work seamlessly across any website.

🎨 Precise Color Correction for Color Blindness

Vision Aid supports scientifically-validated correction profiles for all major types of color blindness:

- Protanopia (red-blind): Corrects red-green color confusion with optimized red compensation
- Deuteranopia (green-blind): Enhances green perception for clearer color distinction  
- Tritanopia (blue-blind): Adjusts blue-yellow color ranges for better differentiation

Each profile uses clinically-researched color transformation matrices that have been proven effective in accessibility studies. Colors are adjusted intelligently to maximize contrast and clarity while maintaining natural appearance.

Powerful Low Vision Enhancements:

Beyond color correction, Vision Aid provides essential tools for users with low vision:

- High Contrast Mode: Dramatically increases contrast ratios to meet WCAG AAA standards, making text and UI elements easier to read
- Adjustable Font Scaling: Enlarge text from 75% to 175% to find your perfect reading size
- Line Height Contro*: Reduce eye strain with customizable line spacing (1.0x to 2.0x)
- Auxiliary Visual Cues: Automatically adds icons and patterns to color-only indicators (like status badges, warnings, and alerts) so you never miss important information

🔧 Smart Per-Site Customization

Every website is different, and Vision Aid understands that. Configure unique settings for each site you visit:

- Different color profiles for different sites (gaming sites vs. news sites vs. work tools)
- Save your preferences automatically—they're remembered when you return
- Quickly toggle the extension on/off per site without losing your settings
- Create and manage custom presets for different activities (reading, work, entertainment)

🔍 Proactive Accessibility Detection

Vision Aid doesn't just correct colors—it helps you identify accessibility problems:

- Automatic Issue Detection: Scan any webpage for common accessibility barriers
- Identifies low-contrast text that's hard to read
- Detects images missing alt text descriptions

- Highlights color-only indicators that need auxiliary cues
