Summary
This placebo-controlled field study tested whether blue light-blocking glasses could mitigate circadian disruption and improve sleep quality and alertness in nurses working night shifts. The findings have practical implications for healthcare lighting design and personal protective strategies for shift workers exposed to artificial light during nighttime hours.
Key Findings
- Abstract is truncated — specific quantitative outcomes (effect sizes, p-values, sleep metrics) are not available from the provided text.
- Study design was placebo-controlled and exploratory, suggesting preliminary evidence rather than definitive conclusions about blue-light blocking glasses as an intervention for night shift workers.
