Comment on 'Autofocus' specs promise sharp vision, near or far - BBC News

Reading how it works, it sounds nightmarish. I only have the myopia so I only know bifocals in theory but it sounds like they’re replacing something dependably consistent with something that’s constantly trying to guess what I want it to do. I don’t like that in any technology but I extremely don’t want it applied to an entire sense.
Put a button on the side that manually toggles between a preprogrammed close mode and far mode then I’m into it.

The thing is that with progressive bifocals, and the right size lense, this is rarely an issue, as you choose the focus you need by simply moving your eyes and head. When setup properly I rarely need to move my head at all for normal day-to-day stuff, as we naturally put what we’re viewing in the center of our vision.
For example, when looking far, we tend to look upward more, so naturally use the upper portion of a lense. When on a computer or reading, we tend to look downward. Driving is a great example, we look forward and up while driving, down to see the dash, and progressives cover that with no problem.
The only time I run into “problems” is when doing really close work for an extended period, like stuff inches from my face. But for those times, I just switch to readers only while I’m doing that work.
