CalmScreen — Eye Comfort

A simple eye-comfort layer for Chrome. Two sliders (brightness, warmth), three presets (day, evening, night). All local.

Easy on the eyes. All day. CalmScreen is the eye-comfort layer Chrome should have shipped with — kept small on purpose. Two sliders. Three presets. One per-site toggle. Nothing else. WHAT YOU GET 🎚 Brightness — gently dim any tab from 100% all the way down to 10%, in 1% steps. 🌅 Warmth — soft amber tint that takes the harsh blue out of long sessions. Same idea as f.lux / Night Shift, except per-tab and on demand. ☀️🌅🌙 Day · Evening · Night presets — one tap each. Day is neutral. Evening is warm. Night is deep amber with low brightness. 🌐 Per-site off — websites where you don't want any tint (banking, design tools, video)? One tap on the header switch and CalmScreen leaves that site alone. Forever. ⌨️ Keyboard shortcut — Alt+Shift+C toggles CalmScreen on the current site, instantly. POWER-USER TOUCHES IN THE POPUP • Scroll-wheel over a slider for ±1% nudges (Shift for ±5%). • Double-click a slider to reset it to default. • Arrow keys work too — focus a slider and tap ←/→. HEADLESS ON THE PAGE CalmScreen does NOT add any floating button, banner, or panel to the websites you visit. The page stays exactly as the site designer intended — just calmer to look at. All controls live in the toolbar popup. WHAT YOU DON'T GET • No tracking. No analytics. No telemetry. No "anonymous usage data". • No servers. No accounts. No sign-in. No newsletter. • No upsells. No ads. No "premium" tier. • No reader mode, no schedule editor, no reminders, no focus mode. We removed every "feature" that didn't pay rent. PERMISSIONS, EXPLAINED • storage — to remember your slider values and per-site toggles, locally. • scripting, activeTab, <all_urls> — to apply the brightness + warmth filter on the page you're viewing. CalmScreen does not read or transmit page contents. It only applies a CSS filter on top of the rendered page. WHY US Most "eye-care" extensions either bury you in settings or paywall the actual feature. CalmScreen is the in-between: two knobs, three presets, zero strings. If you read for a living, write for a living, or just spend too many hours in a tab, CalmScreen will quietly become one of the best things you have installed.
