How Poor Dark Mode Design Reduces Reading Comprehension by 14%

Reading comprehension drops by 14 percent on sites that poorly implement dark mode.

Dark mode has surged in popularity, offering a sleek look and potential eye strain reduction. However, a 2022 MIT study found that websites with poorly implemented dark mode see a 14 percent drop in reading comprehension. This means users may misunderstand content or struggle to retain information—something no business can afford.

Why Does This Happen?

Poorly designed dark mode typically involves:

  • Low contrast: Dark grays on black make text difficult to distinguish.
  • Thin or light fonts: Some fonts appear washed out in dark mode, reducing legibility.
  • Incorrect background hues: Using pure black (#000000) can cause halation, where text appears to glow and strain the eyes.

How to Improve Dark Mode for Readability

To maintain clarity and comprehension, ensure your dark mode implementation follows best practices:

  • Use a high-contrast color scheme (e.g., off-white text on deep gray instead of pure black).
  • Choose readable fonts that are well-spaced and bold enough for visibility.
  • Avoid extreme color pairings that reduce readability or cause visual fatigue.

Optimize for Better User Experience

If your website offers dark mode, test readability with real users and refine your design accordingly. A well-implemented dark mode can enhance the user experience—but a poorly designed one will do the opposite.
