Clarification on ND?
So I'm looking at either buying some ray bans or serengeti's for flying, having read this I am not clear as to whether serengeti's colour enhancement, which is present in their brown drivers lenses, are as effective for flying as a neutral density say like the G15. I get the impression that the data says they are not, but I don't understand why, if a greater amount of difference is being perceived between colours isn't this better than having typical perception?
Further is their much or any difference between a rayban B15 lens and a serengeti drivers lens?
Thanks
