I suffered from myopia, which in my later years became better (I now no longer need glasses). However, as I aged, my ability to see the reticle clearly became difficult no matter how I adjusted the ocular lens. I discovered that I could actually see the reticle better with uncorrected vision.
Same with holographic sites as well. I now can see both quite well.
Depending on your specific eye sight, you may have to try adjusting the ocular lens to extreme positions or try without them for the shot. I know, not ideal, but try something. I even spoke with my eye doctor about a solution, but mine resolved itself as I aged.
I used to wear contact lens, and that posed more of a problem with scopes than I wanted. I started wearing glasses to do load development and looking over the top of my glasses while shooting. That worked best for me.
