After you tweak the diopter make sure you advise if it improves the visibility of the readout for you. When I first read the focus directions it seemed excessive but after doing it I definitely see an improvement on my unit. These are the first pair of binos I have ever owned that had a diopter focus for the right lense. I’m guessing it’s done for the same issue you are having, tweaking the readout to varying eyesight of owners.
