Protect your eyes while you work.

Screen Temperature

Shift your display toward warmer tones with presets or a manual slider — less blue light at night.

• Day — 5000K
• Evening — 3400K
• Night — 0K (deepest warm tone, zero blue light)
• Slider from 0K (Night) to 6500K (cool / neutral)
• Toggle on or off from Home or the menu bar
• Native display warmth on Mac when available; overlay fallback otherwise
• Reset display clears SYE’s effect and returns normal display settings

Eye Rest (20-20-20)

Strict timing by default: exactly 20 minutes of work, then 20 seconds looking away. The next interval starts when your break ends.

• Full-screen break overlay on all monitors
• Break reminders — 5 min and 30 sec on by default; 1 min and 10 sec optional
• Progressive break times — optional; 1st break 20s, 2nd 1 min, 3rd+ 5 min
• Lecture / reading mode — gentler copy for classes and reading
• Skip button — optional; off by default
• Break now and Pause 30 min from the menu bar

Quick start (Home)

One-tap modes for common situations. Pick a duration (up to 2 hours); SYE applies settings immediately and restores your previous setup when time is up.

• Weekday classes — Day temperature + eye rest every 20 min
• Late night cram — 0K night temperature + 30 min breaks + lecture mode
• Active schedules always take priority over quick start

Schedules

Automate temperature and eye rest by day and time.

• Up to 5 schedules (e.g. school hours, late-night study)
• When a schedule runs, it controls SYE until that window ends
• Skip today or tomorrow per schedule
• Schedules override manual changes and quick start while active

Menu bar

SYE lives in the menu bar (not the Dock). Closing the main window keeps SYE running.

• Open SYE
• Toggle screen temperature
• Toggle eye rest
• Break now · Pause eye rest 30 min
• Quit

Battery saver

Reduces background work and skips pre-loading break overlays. Eye rest and schedules still run on time. On Mac, also follows macOS Low Power Mode.

Launch at login

Start SYE automatically when you sign in.

Force stop & Quit

Force stop skips schedules for today, stops eye rest, turns off temperature, and ends quick start. Quit fully exits the app — menu bar icon, overlays, everything.
