Night Light – Warm Screen for Evening Work & Study
A warm, adjustable overlay to ease evening screen time. Drag the Warmth and Brightness sliders or pick a preset, then press F to go fullscreen.
Why reduce blue light?
Blue-heavy light in the evening can suppress melatonin production, making it harder to wind down after a late study or work session. Warmer tones are gentler on the eyes and less disruptive to sleep.
When to use it
Best in the hour or two before bed, or during any evening session where you want a softer, less stimulating screen — reading, journaling, or winding down a long work day.
Pair with your OS night mode
Your operating system's built-in night shift shifts your whole display; this tool goes further for a single dedicated warm screen — useful for a secondary monitor or a distraction-free reading pane.
Warmth vs. brightness
Warmth shifts the colour toward amber; brightness controls overall intensity. For late-night use, try high warmth with lower brightness — for early evening, a lighter touch on both.
