the one that makes character adapt to the dark more easily or is it waste of perk ?

Yes, it works. I don't think it's as potent as Cateye, but it still works.

I found it annoying. But it does work.

any where i can see screen shots of same scene before and after this perk ?

You might try the wiki. Not sure if they have a before and after pic but it does work. Problem is it works ALL THE TIME.
