I had cataract surgery 14 years ago in both eyes. Have mono focus lenses in both eyes. I wear bi-focals with essentially plain glass for far vision. I was myopic and my far vision is now 20/20. Being able to spot other gliders/aircraft quickly is obviously important in soaring. Sharp focus while assessing a field prior to an off-field landing also important to me. So, I'll opt for the acute far vision option and mono focus without the trade-offs. And yes, my sun glasses are bifocal too.

It would be good to hear from pilots with the multi-focus lenses in this forum too.
