Optimizing for just "better or worse" will result in excessively strong correction. If you're only looking at a single letter in the very center of your field of vision, then overcorrection feels sharper and easier to focus on. You don't notice the additional optical artifacts everywhere else. The ideal glasses have just barely enough correction.
However, this isn't an argument against automation, because human optometrists frequently get it wrong too. I agree that it should be automated.
