History of Night Blindness

• Nyctalopia is Greek for night blindness
• Aulus Cornelius Celsus described night blindness around 30 A.D. and gave some ideas for special diets:
  
• "There is besides a weakness of the eyes, owing to which people see well enough indeed in the daytime but not at all at night... But success sufferers should anoint their eyeballs with the stuff dripping from a liver whilst roasting, preferably of a he-goat, or failing that of a she-goat; and as well they should eat some of the liver itself."

• A long time ago, nyctalopia was also known as moonblink
  
• It was a temporary night blindness thought to be caused by sleeping in moonlight in the tropics
