The white sight lines on the top line AND flange are congruent when I'm right over the putter in good position, and when the sole of the putter is correctly resting on the green. The lines are divergent when the toe's up, heel's up, or if I'm not standing over the putter right.
It's my own little alignment aid, but will surely not be to everyone's liking. I've always liked the flange line as a simple alignment aid, and decided to take it a step further. I imagine many would prefer no lines, and find my specs too distracting at address.

I forgot to comment on this aspect last year when you posted. In the late 1970's, I acquired a T-Line mk iV second hand. It is a blade putter, with a T extending from the top line onto the flange, painted white. Each side of the flange part of the T are two yellow lines. Good alignment, and if the putter is horizontal and your eyes are over the ball, the top white line is equidistant between the two yellow lines.
I believe Greg Norman used a similar putter model at Grange East when he won his frst event, the West Lakes Classic.
My T-Line iv still gets a run every now and then, essentially when I want to return to a blade style and try to roll the ball again on the greens.
I am never sure what the alignment aid does when you are on a green with a 3 degree side slope. The alignment is a bit more difficult then!
