Most who like black sights are those young guys that can see them!!!
Some young guys, and many of us old fogies, have a difficult seeing the front sight--esp when against a black background.
I use anything to at least give me a blur of color, Ashley Big Dot, fiber optics, yellow model paint, yellow car touch up paint, etc. Being able to focus on the front sight in a stressful situation is a luxury some shooters do not enjoy.
Yes, I know all about all of the trick glasses, etc. I know of none that can become part of the everyday street wear, so I'll stick with my lineless trifocals, and paint my front sights. GLV
