What is Night Mode?
Night Mode is a Chrome extension that applies a dark theme to any website with one click. It adds blue light filtering and adjustable font sizing on top of the dark mode so readers can tune brightness and text size for long reading sessions. The Chrome Web Store listing is the install point and the extension runs entirely in the browser. The store listing was unreachable for a fresh fetch, so the description here stays close to what the listing publicly claims.
Why Night Mode works
Many sites still ship without a built in dark mode and reading them late in the day strains the eyes. Rather than tweaking system level settings or installing a heavy theme tool, the extension flips one site at a time into a darker view with reader friendly font sizing, which is faster than configuring per site stylesheets.
Night Mode features
- One click dark theme. A single toolbar click converts the current page into a dark theme so readers do not have to wait for sites to ship native dark mode.
- Blue light filter. A yellow light filter sits on top of the dark theme to cut blue light during late night reading.
- Font size controls. Built in font size adjustment lets readers scale text up or down on any site without zooming the whole page.
Who Night Mode is for
- Late night readers who spend long sessions on news and documentation sites that have not added native dark mode.
- Knowledge workers with sensitive eyes who want a consistent dark and warm tone reading view across every site they visit.
- Students reading long form research papers and lecture notes in the browser who want larger text and lower screen glare.
