I am looking for a sight for a couple of .22 pistols. I have an astigmatism that makes red dots look like a red football or red squashed spider, and green is even worse!

I suppose I could spend several thousand dollars to get my eyes fixed, in hopes that maybe I could see a red dot easier, but in the meantime, does anyone know of an old fashioned cross hair type scope that does not have magnification? I've tried a 2x Leupold that came with a Redhawk I bought, and that was okay, but not very fast on target acquisition.
Thanks.
