I know all circle lenses do, but which are the most effective? There are ones with the dark circle around them and whatnot. But I do want them to look natural. I have naturally blue eyes. Green ones would be nice, but I like blue!
  
  Links to colours that would suit me would be nice! Also if you include links, use trusted websites!
  
  Thanks :)
  
  And yes, I do realize circle lenses can be dangerous, but I will only wear them for a couple of hours!
