Yes, they help with my aging eyes a lot. The Lyman one is very light, all plastic compounds but mine has lasted years. The suction cup does not stick quite as well as when new, but it's still ok.
I don't understand the physics of the thing, but the result is very much like cranking camera aperture way down - greatly increased depth of field. Without using it, my front sight is fuzzy and my rear sight is a double image; with it - they are both pretty clear, quite effective.
