When I had cataract surgery , I opted for having my left (M shooting eye)
optimized for distance and the right eye for reading and close work.

I had  this mono-vision correction with contacts some years before and it
was very successful, and remains a great solution for me.

I now do not need glasses for day to day work, and even my astigmatism was
addressed with the implant.

If I hold the M9 to my left eye, the image in the viewfinder is crystal
clear, while there's some softness using my right eye.

I do own a pair of glasses that bring the eyes together for prolonged
reading, so my right eye is not working so hard, but I don't need them for
most reading.

The reason this works is your dominant eye is the one that primarily
focuses on an image.  The other eye helps, but your the brain pays much
more attention to the dominant eye.
