Usually you have one eye that is dominant so modest errors in the other
one don\'t show. You will have a headache though if a lens falls out.

I have the same issue, which is particularly important for close work.
But ophthalmologists can also adjust with both eyes open, if one asks.
Typically, one also specifies a working distance (I use 14\") and they
do better/worse adjustment with a small eye chart held at that
distance.
Note that the typical better/worse algorithm assumes that the current
prescription is close, so they don\'t test a third point between, and
will see no change between better/worse options if the search is far
off. This happened to me, discovered when I operated the better/worse
instrument myself, in the dark. I don\'t know what triggered me to do
that.
Turned out that the cylinder angle had drifted off by 100 degrees over
a few years, and that cataracts can do that as they ripen.
What the ophthalmologist now does is to use a Leitz automated
refractometer (name?) used for fitting contact lenses, even though I
don\'t use contact lenses. This instrument always finds the correct
rough focus.
So I make up my own prescriptions, simple spherical corrections, and
buy them from Zenni.
The only problem with this is that no final adjustment to your face
can be done from China.

Both eyes is always marginally better than either one on its own but the
dominant eye gets the lions share of attention on seeing fine detail.
Binocular vision is handy for judging distances though.
So I make up my own prescriptions, simple spherical corrections, and
buy them from Zenni.
Provided that you don\'t have much astigmatism then that should work.
But you really need to find a better optometrist! When mine does me I
can read one line or two lines below what is normally considered 20:20
vision with the full correction applied in his test frames.
My distance vision is to that precise prescription and tack sharp. My
close up are both the previous prescription and more than adequate.
I was slightly horrified to be told that my distance vision was still
within the legal parameters where I could drive without glasses!
Water, water everywhere nor any drop to drink.
That was a high school memorization task.
I don\'t want anyone adjusting my face.
Zenni works, and the glasss are so cheap that I can iterate if it\'s
not perfect. That spins off lots of spares.
I suspect that a lot of local glasses stores order Chinese now. But
still charge $200 for frames.

Zenni works for me. I have a regular bifocal pair and one set up for
reading/computer. Bifocal where one is about a foot away and the other
takes over around 2 feet for working with the computer.

When Ronald Reagan was President, the USDA declared that ketchup
could be considered a vegetable portion in school lunches. Intense
mockery followed.

I have the same issue, which is particularly important for close work.
But ophthalmologists can also adjust with both eyes open, if one asks.
But the setup is head immobile looking at an eye chart. In real life,
scenes change and people move around.
Typically, one also specifies a working distance (I use 14\") and they
do better/worse adjustment with a small eye chart held at that
distance.
I\'m nearsighted so only use glasses outdoors, or watching a movie
maybe. No glasses for computing or average close work.
Note that the typical better/worse algorithm assumes that the current
prescription is close, so they don\'t test a third point between, and
will see no change between better/worse options if the search is far
off. This happened to me, discovered when I operated the better/worse

They should let people turn the knobs themselves.

I had macular hole surgery a few years back on my dominant eye and the
sulfur hexafluoride gas tends to hasten cataract formation. I\'ve been
kicking the cataract surgery can down the road so my dominant eye is also
the less functional one. That leads to some interesting visual effects.
