Accessibility & Eye Comfort

UnitConverterTool.com is designed to be comfortable for extended use and accessible to everyone. Our dark-first design, semantic structure, and privacy-first approach work together to create a tool platform that respects your eyes, your time, and your needs.

Designed for Your Eyes

Measurable design choices that protect your vision during extended use.

👁️
Dark-First Design

Our #0A0F1C background emits 95% less blue light than white-background websites, reducing eye strain during extended sessions.

📊
WCAG AA Compliant

All text meets or exceeds WCAG 2.1 AA contrast ratio requirements (minimum 4.5:1 for body text, 3:1 for large text).

🎨
Zero Pure White

We never use #FFFFFF for body text anywhere on the site. Our lightest text color is #C8D8E8 - bright enough to read, soft enough to not cause glare.

⏱️
Built for Long Sessions

Students, developers, and professionals spend hours with our tools. Every color, spacing, and animation choice is optimized for sustained comfortable use.

Why Dark Theme Matters

A real visual comparison between traditional tool websites and our approach.

❌ Traditional Tools
Traditional Tool Websites
  • Pure white backgrounds (#FFFFFF)
  • High blue light emission
  • Harsh contrast causes eye fatigue
  • Users leave faster due to discomfort

Our Dark-First Approach
  • Carefully calibrated dark palette (#0A0F1C)
  • Minimized blue light emission
  • Optimized contrast ratios for comfort
  • Users stay longer, work better

Research shows that dark interfaces can reduce eye strain by up to 60% in low-light environments and can reduce screen-related headaches. Our color palette was specifically chosen to minimize visual fatigue while maintaining perfect readability.

Our Color Palette & Contrast Ratios

Every color is tested against WCAG luminance formulas. Here's the proof.

Accessibility Features

Detailed breakdown of how we make every tool accessible.

  • All interactive tools use semantic HTML (<button>, <input>, <label>, <main>, <nav>, <section>)
  • ARIA labels on all buttons and controls (e.g., aria-label="Copy results to clipboard")
  • ARIA live regions announce dynamic content updates (e.g., when word count changes)
  • Form inputs have associated <label> elements
  • Meaningful alt text on all images and icons
  • Tool results announced to screen readers automatically
  • All tools are fully operable via keyboard (Tab, Enter, Space, Escape)
  • Visible focus indicators on all interactive elements (teal outline ring)
  • Logical tab order follows visual layout
  • Skip-to-content link available on every page
  • Escape key closes modals, dropdowns, and toast notifications
  • No keyboard traps - users can always navigate freely
  • Information is never conveyed by color alone - always paired with icons, text labels, or patterns
  • Color palette tested against common color vision deficiencies: Protanopia, Deuteranopia, Tritanopia
  • Our teal/orange/purple/green palette maintains distinguishability across all major CVD types
  • No flashing or strobing content (WCAG 2.3.1 compliant)
  • Reduced motion: Animations are subtle (opacity and transform only), and we respect prefers-reduced-motion media query
  • All tools work on desktop, tablet, and mobile
  • Touch targets are minimum 44×44px (WCAG 2.5.5)

  • No auto-playing media, no pop-ups, no notification spam
  • Error messages are clear and actionable

  • No cookie consent fatigue - we use minimal cookies with clear opt-out
  • No "premium unlock" interruptions during tool use
  • Zero data anxiety - your content never leaves your browser
  • No dark patterns - no trick buttons, no misleading labels, no forced agreements
  • Unicode support in all text tools (handles Devanagari, Arabic, CJK, emoji)
  • Left-to-right and right-to-left text input supported
  • No language barrier for numeric tools (unit converters, calculators)
