Sorry i could not respond to a couple of the questions earlier, but i just got off work. I have not been to an eye dr in quite some time but the last time I went, I was JUST above 20/20. the slightest astigmatism(sp) in left eye, right eye perfect. Im right handed and right eye dominant.
As for what i see, Alan hit it dead on. with both eyes open when i focus on something at a short range (arm length-the sight) the objects in the distance appear to double and get fuzzy. I see what I think I should be seeing, a crisp sharp edge of the front sight post on top of a blurry silloutte target, my problem is there appears to be 2 of them. I tried the tape over the left eye thing and that may do the trick for me, just dont know how silly im gonna look at my first match with my shooting glasses taped up, lol.
Maybe the two-eyes-open thing isnt for me, idk. ill have to try both ways in the next few range trips and see what works better. I just think having them open will be able to save me a step or two (close eye, shoot, shoot, open eye, find next target, close eye, repeat).
