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 the Temp tab or menu bar
• Native display warmth on Mac when available; overlay fallback otherwise
• Reset display clears SYE’s effect and returns normal macOS settings

Eye Rest (20-20-20)

Regular reminders to look away from the screen — default every 20 minutes, for 20 seconds.

• Interval: 5 min – 2 hours · Break length: 5 sec – 10 min
• Full-screen break overlay on all monitors
• Reminders before each break (1 min and 10 sec always on; 5 min and 30 sec optional)
• 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

Guided Eye Exercises

Six on-demand routines with per-step timers. Longer exercises use an audio chime when each step changes.

• 20-20-20 Focus — 20 sec
• Figure Eight — ~1.5 min (audio)
• Near–Far Focus — ~1.5 min (audio)
• Blink Reset — ~45 sec (audio)
• Palming Rest — 5 min (audio)
• Distance Gaze — 5 min (audio)

Menu bar

SYE lives in the menu bar (not the Dock). Right-click the icon for quick actions.

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

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

Corner timers

Small draggable HUDs for time since last break or session length.

Active hours

Limit when SYE auto-starts on login (e.g. 9:00–18:00). You can still turn features on manually anytime.

Battery saver

Reduces background work and hides corner timers. On Mac, also follows macOS Low Power Mode.

Launch at login

Start SYE automatically when you sign in.

Force stop

Instantly stops everything: skips all schedules for today, stops eye rest, turns off temperature, ends quick start.
