  Vision 
   Vision senses light (radiant energy). Photons emitted by, or 
  reflected by, objects provide information about the objects.

  UNDERSTANDING VISION 
   The sense organ for vision is the eye. It detects radiant energy and feeds it to a 
  nerve system that processes the information. A sophont’s eye is sensitive to a range 
  of light wavelengths (bands) which correspond to colors. 
   A sophont with a sense of vision has eyes and can see. A sophont without the 
  sense of vision is blind.

   Range. Roll Dice equal to Range. 
   Vision. The Vision Constant for the Race (Human = 16). Higher numbers are better: a 
  sophont with Vision 20 has better vision; one with Vision 12 has worse vision. 
   Benchmark. Object Size minus Range. If zero or less, the Action cannot be attempted. 
   Mods. Mods based on circumstances from the Master Mods table (as applicable). 
  Higher Mods are better. 
   
  THE VISION CONCEPT 
   The Vision Action is the referee’s opportunity to present sense information to a 
  character. When the character indicates he is trying to see what he can (“I am scanning 
  the horizon” or “I am looking around”), the referee resolves the Vision Action based on the 
  Vision Constant, Range, Object Size, and other details. 
   Once an object is noticed, the character continues to see it until it moves out of range or 
  somehow becomes hidden. 
   
   For example, human Eneri Dinsha V-16-RGB has landed his scoutship on a broad plain. 
  He steps out and looks around. It is ordinary daytime. 
   There is a cargo mover Size=6 moving near the horizon Range=6. 
   Vision Constant = 16. Benchmark = Size minus Range = 6-6 = 0. Mod = +2 Vfast. 
   The referee hands the player 6D and says “Roll.” He must roll 16 +0 + 2 = 18 or less on 
  6D to notice the cargo mover. He has about a 28% chance of seeing it. 
   Option1. Eneri rolls 12. The referee tells him: “There is a Cargo Mover out near the 
  horizon, moving from left to right, appears to be moving quite fast. 
   Option2. Eneri rolls 21. The referee tells him: “The landscape looks fairly common. 
  Some flats, a few rocks, some hills off in the distance.” He’s probably not looking very 
  hard. 
   
   Eneri can go back inside because there’s nothing to see. 
   Or he can keep looking and try again.
