CalmScreen — Eye Comfort

About

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.
