I had a provider years back who took a very different approach.
Two *large* letters that you examined CASUALLY as he altered
the settings on the phoropter. As you *knew* what the letters
were (they never changed), you didn't "try" to see them clearer.

As a result, you concentrated on "what looks better" instead
of trying to see fine detail.

After coming to satisfactory settings on the phoropter, he'd THEN
put up an eye chart and ask to see how far you could comfortably
read -- to verify the settings!

that is how it has been done for me for decades now. nothing new or unique
here.

I've not seen this approach since the early 80's. Eye doctors (optometrists
and opthamologists alike) all seem intent on using a multiline display
(currently a projector using a mirror to "shorten" the size of the
room needed, otherwise) with ever shrinking (and changing!) letters.

Once the "provisional" Rx has been dialed into the phoropter, the
examiner has you review the same chart to see how/if your net vision
has improved.

[SWMBO went last week -- "new" doctor, same projector approach]

I've not seen the "two large letters" (i.e., 1 foot tall) approach
anywhere but that *one* doctor's office. As a result, I am always
suspicious of the Rx's I've been given in the years, since (which
all seem to suggest my vision hasn't changed in 30+ years! Do I
believe that??)

Could be. Can you see? That is what counts.

Define "see". :

I can sense light vs dark. I can tell round vs. square. I can read
at normal reading distance (haven't developed the "arms too short"
problem). I can spot a pin on the floor from several feet away.
Etc.

But, I can't read the markings on integrated circuits ("chips")
anymore, without lots of light and magnification. I can't remove a
sliver from my finger without "magnification". I often can't make out
the names on street signs at a distance (but can reason that "the first
letter is round-ish so it's probably OAK street and not ELM"). I
can't recognize faces in passing cars at night (and have to rely on my
knowledge of who drives which types of vehicle, etc.).

I can't legally drive without my glasses. Yet, my Rx is so weak that
folks can mistake it for "clear glass".

So, can I see?

I don't see why not...
