Virtual Darkness
By using amber lenses, researchers were able to block blue spectrum light, which affected the "physiology of human circadian rhythm ... suggesting a circadian effect." This effect was previously noted with "amber-tinted safety glasses" which "preserve normal nocturnal melatonin levels in a light environment which otherwise completely suppresses melatonin production."

Famous quotes containing the words virtual and/or darkness:
“Tragedy dramatizes human life as potentiality and fulfillment. Its virtual future, or Destiny, is therefore quite different from that created in comedy. Comic Destiny is Fortune—what the world will bring, and the man will take or miss, encounter or escape; tragic Destiny is what the man brings, and the world will demand of him. That is his Fate.”
—Susanne K. Langer (1895–1985)
“A darkness out of Asia that had crossed
Old Attic grace and Spartan discipline
With violence.”
—Robert Frost (1874–1963)
