Is there a formula for this? There are two other parts to this question, but if I get this the others won't be hard to get.
  In the dark, it will increase the size of your iris, which lets light in to the eye. When its bright, the iris shrinks to let a smaller amount of light through. The increasing and decreasing of the iris can take several seconds to adjust which is why at first you cant see anything in a dark room.he two ligh energy waves that you can't see are ultra-violet (UV), and infra-red (IR).  Ultra-violet light waves are measured at 380nm and below, infra-red light waves are â¦ 750nm and above.  Normal light that you can see resides between these two regions.
