  • A blue-light-blocking frame built for the hours after dark.
  • Crimson tint, not pale amber — it absorbs far more of the short-wavelength light that delays melatonin.
  • Wide enough to block light reaching your eyes from outside the lens.
  • Wear it for the two hours before bed, not as you get into it.
