Eye-Care Automation
The best focus tool is one you never have to operate. VeilWin’s automation rules turn dimming and eye care into a fully automatic flow: scheduled on/off, appearance-following, rest reminders.
Preset rules
VeilWin ships with 5 automation rules (Settings → Automation), ready to use and individually toggleable, editable or deletable:
| Rule | Trigger | Action |
|---|---|---|
| Night auto-dim | Daily 22:00 | Enable dimming |
| Morning auto-restore | Daily 07:00 | Disable dimming |
| Dim on dark mode | System switches to dark | Set intensity to 35% |
| Rest reminder | Every 20 minutes | Desktop notification |
| Force break | Every 60 minutes | Force break for 5 minutes (screen fully dimmed; off by default) |
Triggers
| Type | Description | Example |
|---|---|---|
| Time of day | Fires once per day at HH:MM | Enable dimming at 22:00 |
| Interval | Fires every N minutes, anchored to enable time | Remind a rest every 20 minutes |
| Appearance | Fires when the system switches light/dark | Dim on dark mode |
Actions
| Type | Description |
|---|---|
| Enable/disable dimming | Toggle the dimming state directly |
| Activate profile | Switch to a specific profile |
| Set intensity | Adjust the intensity (0–100%) |
| Remind break | Desktop notification, no state change |
| Force break | Fully dim the screen for N minutes, focus tracking suspended |
Custom rules
- Open Settings → Automation
- Click “New rule” and name it
- Pick a trigger (time / interval / appearance) and an action
- Save; multiple rules match in list order, first match wins
Rest rhythm (20-20-20)
The ophthalmology-recommended 20-20-20 rule: every 20 minutes, look at something 20 feet (6 m) away for 20 seconds. The presets follow this rhythm:
- Every 20 minutes: a desktop notification reminds you to rest
- Optional: every 60 minutes, a forced 5-minute break (off by default; enable in Settings → Automation)
During a forced break you can stand up and stretch or look out the window. Skip it from the tray menu (or the banner in Settings) if you are in the middle of something.
Typical uses
- 22:00 auto-dim, 7:00 auto-restore — no more manual toggling at night
- Follow dark mode: low intensity for light UI, deeper dim at night automatically
- Forced breaks: turn on the preset if you want an hour of coding to end with a 5-minute full-screen dim
