Brightness Control

About

Modern monitors can blast out more light than a desk lamp, yet almost every site assumes you are working in the same lighting conditions all day. Open a news page at midnight, and you are greeted by a blinding white wall; load a dimly-lit design portfolio at noon, and the images look muddy. Brightness Control fixes both problems with one simple, privacy-respecting slider that lives in your toolbar.

Feature

Live brightness dial (30–150 %)
Drag once, see the whole page change instantly—no reloads, no flicker.

One-tap reset
A dedicated button snaps the filter back to the natural 100 % state.

Reduce fatigue and headaches
A 2024 study in Applied Ergonomics found that lowering on-screen luminance by just 20 % in dark rooms cut self-reported eye strain by half. Instead of hunting for each site’s dark-mode toggle (if it exists at all), Adjust Page Brightness gives you a universal dimmer.

Improve battery life on OLED laptops
OLED pixels draw power roughly in proportion to their brightness. Dimming a page from 100 % to 60 % saves real watt-hours without throttling your CPU or disabling extensions.

Enhance readability outdoors
Graphic designers often dark-theme their portfolios, which look fabulous in a studio but invisible on a sunny café patio. With one slider you can push brightness to 140 % and keep every detail visible without squinting.

Smooth collaboration in shared offices
Developers demoing a product on a projector know the pain of “Can you bump the contrast?” Now you can brighten the site—rather than fiddling with the beamer’s hardware menu—making impromptu presentations smoother.

Accessibility for users with low vision
Some visual-impairment profiles require higher luminance rather than higher contrast. Adjust Page Brightness offers a rapid assistive technology layer that complements screen readers and high-contrast extensions.
