ADVICE

Swap Lenses By Time Of Day

  • Use daylight (yellow) lenses during office hours to block harmful shortwave blue while retaining alerting light.
  • Switch to sunset (red) lenses in evening to nearly eliminate stimulating wavelengths and preserve melatonin.
ANECDOTE

Real Users Who Stopped Sleep Drugs

  • Matt shared customer stories: one woman weaned off 25 years of sleeping pills using sunset lenses.
  • Parents used red lenses to wean a child off chronic melatonin dependence.
INSIGHT

Light Effects Depend On Dose

  • Light biology is dose-dependent: intensity, duration, wavelength, and timing all shape effects.
  • Short, low-intensity exposures in studies can understate real-world impacts of prolonged indoor lighting.
