    My guy doesn’t do this except for a quick sanity check. Or maybe because patients expect it? They have your prescription the second you look in the auto focusing machine. Hell, someone invented a lens for a cell phone that does it.

    The optometrist is looking at your eyeball health and related medical issues. The clicky thing is mostly performative.

      Hi I’m an ophthalmologist. The auto refraction is good for a baseline, but the manifest refraction is necessary for the best prescription. Also lots of things can affect the auto refraction like dry eyes, cataracts, and macular degeneration.
