Have you ever noticed how people with vision deficiencies often like to brag about how bad their eyes are? I don't really know why that is, and I tend to do it myself. It's kind of like the mythical boys' locker room conversation, with "inches" replaced by "diopter" and "penis" replaced with "eye."
Mine are 8.5/8.0.
—Oh, mine are both 8.5.
Well, it's not how bad your vision is; it's how you use it.
—That's just a lame excuse that people with good vision use.
