Optimizing the Potential Utility of Blue‑Blocking Glasses for Sleep and Circadian Health
Summary
Discusses when and how to use blue‑blocking glasses, highlighting applications for night‑shift workers (e.g., morning commute, pre‑sleep).
Why It Matters For Night Shift Workers and Night Owls
Evidence here how timing and spectrum of light on shift versus before daytime sleep shows sleep & alertness for night‑shift workers and night owls. Together with other trials, it frames light as a measurable lever for on‑shift alertness and next‑day sleep, not just ambience. For people who work nights, that frames an everyday choice (when you eat, how you light the end of a shift, how rest is split) as part of the mechanism, not just routine.
