light-therapy measurement context
This topic covers a health or wellness approach with a distinct operating role: light-therapy measurement context interprets a light session through actual illuminance at viewing position, distance, angle, duration, time of day, and baseline rhythm.
- With light-therapy measurement context in view, its value depends on whether that mechanism matches a clearly stated purpose.
- Before relying on light-therapy measurement context, evaluate lux at the eyes, device distance, session start, adherence, sleep midpoint, mood trend, glare, and concurrent treatments rather than relying on the category name.
- In a light-therapy measurement context decision, a central boundary remains: brightness stated on a box does not establish the exposure reaching the user's eyes or the cause of improvement.
