I use the EasyHit sight in conjunction with the lens taped. I have done this not only for target shooting but for hunting, both with very good results.
It takes time to adjust but it does work.
For me, just the use of the EasyHit sight alone (w/o lens tape) would not work as the sight is for the initial point of reference only. Once the target is released, I never look at the sight again, just the target.
If you're talking about the one with the long tube in front of the bead they didn't work for me. If I changed my comb like from 16 to handicap I couldn't see the bead at all. I've come to the conclusion just to live with being a one eyed shooter and do the best I can.
I have used one (still do occasionally) & it seemed to be more help (to me) when I missed because by then my focus has changed a little & I see the glow worm & the target at the same time, otherwise all I see is the target & a fuzzy blob as I pull the trigger (the muzzle) & can't really see a relationship between the muzzle & target. just my experience.

Does anyone here shoot as good as Harlan Cambell? I understand he uses one. Do they solve cross dominance-for some-probably-for others-maybe not. The only one that eliminates cross dominance for everyone all the time is to close one eye!!
Some shooters have posted claims of having corrected cross-dominance with the Easyhit by training themselves to shoot with two -eyes open thus retaining binocular vision.It's worth a try, because the 2.5 mm sight works great for many who don't have cross-dominance, like myself.
