Brain has been designed in a wonderful and complex way; I think it can adjust to different HAs easily than people think, it’s a no-brainer to “him” (the brain)
Bifocal or varifocal aren’t always a good choice, everyone is different.
And you read time and time again on this forum, people like this or that HA because they suit their lifestyle and requirement, but there is always something missing, which some other brand offer, hence my post.
Why switch, if you can afford a backup pair/second pair, so you can fill the missing piece of the puzzle.
