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) |
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
- Every 60 minutes: a forced 5-minute break — the screen goes fully dark until the duration ends
During a forced break you can stand up and stretch or look out the window; the notification’s action button skips it early (e.g. while presenting).
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: after an hour of coding, a 5-minute forced break protects your eyes
