I had mine done a couple of years ago Dave.
The halos disappeared for me after a few months, I think your brain just tunes them out. I don’t even think about them now and I just drove 300 miles overnight.
I find using a FFP scope a crisp reticle image can be sensitive to head position as you have, as you explained, multiple concentric lenses. I find myself tweaking the rear ocular setting on occasion especially for ELR to get a perfect image.
I do find myself hitting the light switch earlier as my pupils don’t seem to dilate as much as I recall in dim light.
Being able to see turrets/charts/phone/kestrel without reaching for the old man glasses outweighs any other inconvenience!
