Accessibility Features in Dark Mode
Controls designed for real visual comfort — not just a trendy theme.
Eye Protection Mode
A dedicated Eye Protection option applies an eye-friendly theme instantly — tuned for comfortable long-session reading.
Adjustable Contrast
Choose your own text and background colors — raise contrast for low vision or soften it for light sensitivity.
Smooth Dimming
The dim overlay eases brightness gradually instead of a jarring light-to-dark snap.
Custom Color Themes
Pick tones that work for you — warm darks, muted contrasts, or specific color combinations that suit color-vision needs.
No Flash of White
Night Mode applies before render, avoiding the bright-white flash that can trigger discomfort for sensitive users.
Fully Private
All settings live locally — accessibility tools shouldn't surveil you.
Dark Mode as an Accessibility Feature
For people with photophobia, migraines triggered by bright screens, or general light sensitivity, a white webpage isn't just unpleasant — it can be genuinely painful. Dark mode stops being a preference and becomes a requirement for using the web at all.
One Size Doesn't Fit All Eyes
The problem with built-in dark modes is that each site picks its own colors — and what one designer calls 'dark mode' may still be too bright or the wrong contrast for you. Turn Off the Lights puts the colors in your hands: pick the exact background and text combination that your eyes are comfortable with, and it applies everywhere.
Eye Protection, Built In
If you'd rather not tune colors yourself, the Eye Protection feature applies a carefully chosen eye-comfort theme in one switch — combined with the schedule, your screen stays comfortable around the clock.
Open Source, Private, and Free — Always

It has been in continuous development since 2009 and remains one of the most trusted browser extensions available, with millions of active users across all major browsers.
