Behavioral and ergonomic changes around screen use — reduced session length, breaks, and proper screen placement — to slow tear evaporation during digital tasks.
| Practice | Description |
|---|---|
| Reduced continuous screen time | Sessions <2 hours with structured breaks |
| Screen distance & angle adjustment | Lower screen so gaze is slightly downward, reducing exposed surface area |
| Night-mode / blue-light filters | Reduce strain in low-ambient-light environments |
