Across 17 RCTs, blue‑light filtering lenses showed little to no short‑term benefit for visual fatigue or sleep versus non‑filtering lenses; evidence quality varied.
Collected studies how timing of light, sleep, meals, and schedules maps findings showing sleep & alertness for night‑shift workers and night owls. Overall, the data make the schedule itself visible in physiology, not just in how people feel subjectively. For the audience living on night schedules, the key meaning is that the schedule’s timing choices show up in measurable outcomes.
