I took a different route that the other responders. I am nearsighted, with astigmatism, but since I was a cop I needed to see the sights at any time. I got glasses with "occupational lenses", i.e., a TRI-focal! My middle lens is for distance, the bottom lens is for reading, and the top lens (slightly smaller than the reading lens) is to focus just past the end of my outstretched arms, on my gun sights. I see the target normally, then dip my head slightly while drawing and I'm right on the front sight. Not the cheapest solution, but it works all the time.
