May I suggest you have a certified instructor evaluate your shooting. They can tell if your non-dominant eye is taking over or not. Sounds more like you may not be seeing the left to right shots as you used to, or in a timely fashion with your diminished vision in your left eye, but it’s impossible to say for sure without observing. An experienced instructor will be able to assess what’s going on more than likely. It’s next to impossible for the shooter himself to tell….even a guy that shoots at a very high level. There’s several reasons for a miss, eye problems only being one of the reasons.
