    You know, it makes me wonder how that works. Because most of the time, they get the prescription right, even though, for the most part, we only guess which one feels right to us, even though, to us, one and two look practically the same.

      I think part of the image processing is done subconsciously and so we can pick up the minute differences in image quality by feel, even when we can’t say what exactly is different.

        That makes sense. Our subconscious is better at picking up the small details than our conscious mind, because it takes more effort for us to think about it. That’s why they say “go with your gut” because our brains calculate things subconsciously. It’s why we can do things without thinking about it.

      My guess is that if one and two look the same, both are equally close to ideal and thus it doesn’t matter which one you pick.

          They might not, but they are making sure that you do or don’t. If you can see the minute change, then you would appreciate the specificity.

      If one and two look the same to you, does it matter which one is prescribed? Can you even say that the prescription is correct?

        If they look the same, you are prescribed the weaker of the two, to avoid overcorrection, which can worsen your eyesight over time.

          I haven’t done a test since I was a child because I generally do fine, but I wonder if some people need additional instruction about what to look for. Like the two “look the same” because they don’t know what to look for. Maybe just a “Is the apostrophe a line or a dot? Okay, how about now?”

          One, or two, which is better? They’re just questions, odd, designed to determine the optimal prescription. Shall we continue? Describe in single words, only the good things that come to mind about your eyesight.
