I have astigmatism and for the ranges where a Red Dot is ideal its not an issue. For small targets and precision shooting your better off with a scope.

Simply having astigmatism does not negate the utility of a RDS. The military and LEO communities reflect society in general and for the most part the RDS works as intended. I have 20/18 vision with a slight uncorrected astigmatism and the RDS is the way to go. My wife has corrected vision with a bad astigmatism and sees only a bundle of grapes through my Aimpoints. An Acog TA44SG works much better for her. This is still much faster for her than irons. The slight 1.5X magnification is all it takes. If someone doesn't prefer an RDS that's their choice and I wouldn't try to change their mind, for them. For the vast majority of shooters the RDS is the best answer we currently have.
A rather intresting article from Kyle Defoor. This is the first time I actually read numbers from a reliable source as to speed.
