Took your advice and and spent my dryfire time today working non-dominant eye/ support side. It's been a long time since I practiced that. I was having my dominant eye superimpose non magnified information right in the center of my crosshair. If I closed my dominant eye quickly I could get a good sight picture for a while. I could also consciously try to burn through my dominant eye information and I could but it was by no means easy. Is this just like training a muscle where more reps make it second nature or are there tricks to get your eyes to key off the crosshair? I could only do about 20 minutes and my eye actually feels very tired.
