Im buying some colored contacts and im wondering,
  When they ask the quesion: how much power?: im wondering how much power i will need if i want to have green eyes, but naturally i have dark brown, should i use the highest power? is its power scale one that has 8 as the highest, 0 the lowest, or vice versa?
  Please help!
