here is a cut/paste of some stuff I typed in the following thread:

you can only focus at one distance at a time (assuming good vision). If the FS is in crisp focus, the target will be out of focus and will get more so the farther away. If both eyes are open while doing so you will also see two targets. On the other hand, with a crisp focus on the target, the sights will be out of focus and you will see two sets of sights. Pay close attention and you should see the target going out of focus when looking at the FS.
The goal here is to make the "doubling" effect not matter. It happens; it's the physics of the human eye. Let it.
...establish an index, which means establish a "platform" that always puts the sights between your eyes and target. ... do the following in dryfire...
Keep the gun down at a 45-degree angle and focus intently on the target. Now slowly bring the gun up in line with your eyes while still focusing on the target. (Don't worry about which set of the "double set" of sights comes into line) Then slowly bring your focus back to the FS and focus intently there. This is super slow motion of what should happen on every target transition.
What you should start to see happen after doing this over and over and over is that you start to always bring the "correct" set of sights in line with your eye. And as you shift the focus to the FS, the sights are always in line with the "correct" target. We're building that index which is the foundation to solid shooting.
every shooter who ever learned to shoot with both eyes open struggled with the same issues at some point. It's not easy but when you're done climbing the mountain the plataue on top is sweet.
Keep it up, and you'll learn that there are exceptions to the above, and even that focus on the FS isn't always the right answer. But you're on the right path.
