Just learned about that while we were chatting at the counter. Apparently the surgery tricks your brain. The condition itself seems like it would be really weird but the brain is powerful to adjust for it.That's called monovision, which is what I have. They set your dominant eye for distance vision, and your other eye for near. I got the distance eye done first, and then they gave me contacts for the other eye to let me get used to how it would work - and to allow me the option of getting both eyes done for distance if I didn't like the monovision.
For the first few days it's awkward, until your brain learns to ignore whichever eye isn't giving it the correct focus at whatever depth you are needing at any given time. Once you push past that, it's a great idea.
Just be careful though. Monovision will disqualify you for some jobs. Truck drivers (or any driving job that falls under the Department of Transportation rules). Pilots have to wear glasses to give both eyes 20/20 at near and far distance for 6 months before they can get a waiver.
