Question for those of you that know more about optics than I do...

If you're left eye dominant, have slight astigmatism in the right eye, and are using optics of 3X or greater, do you have to shoot lefty to be accurate?  Will you always be off target if you shoot righty?

I am right- handed and have astigmatism in both eyes, my right eye is worse, so my dominate eye is my left eye hence I shoot left-handed.

I ahve owned and shot a Aimpoint with no problem, my TA11D Acog 3.5 also worked very well, the triangle was sharp.
If you buy a ACOG its says that 95% of people should have no problem with the Bindon Aiming Concept, if you do, shoot with one eye closed.

BAC is explained at Trijicon website.

I have a left master eye and shoot right handed (My eyes changed on me after years of use, the TRAITORS!).  I have no problems shooting right handed and using an Aimpoint.

I have trouble using EOTechs and Aimpoints but ACOGs and the CQ/T work very well for me.

What works for me was I had my shooting glass taped at the left eye. But I did not cover it all,I started with many sizes my goal is to still use my left eye in an angle on reloading and panning the targets. but when I aim the tape blocks the left eye view. The tape is more located at the bridge of the nose or at the center. Now if there's a barricade and you are going to shoot left handed dont' forget to remove the tape or you're end up cursing yourself.
