Field test.
An old friend of mine told me she had to get a field vision test, and of course my imagination immediately ran away in mistaken directions.
As if she and the doctor were field-testing munitions rather than vision. Better take this out to the testing ground where it's safe!
My next thought was that this was like a field sobriety test, only instead of reciting the alphabet backward starting with the letter M, she would have to read the Snellen chart upside down while standing on one leg.
But no, the test is not about being in a field but rather testing the field of vision, and is more properly called the visual field test (or visual field acuity test). How much can you see in your field of vision that you should be able to see? It's an important test for glaucoma, Graves' disease, stroke, and so on, according to the American Academy of Ophthalmology. (Note that the word ophthalmology is so frequently misspelled that it's almost an eye test on its own. I see what you did there, AAO -- I see very well.)
There are actually several different types of field vision tests, depending on what the concern is and how much insurance you have. (Joke! I kid because I love.)
Fortunately none of these very serious conditions is a problem for my friend, but it's still a troublesome one: eyelid droop. In her case it's caused by dermatochalasis, or baggy skin in the upper eyelid. It cuts off a serious amount of upper-shelf vision. It's not a serious problem yet, as long as she's not about to be a victim of bird strike or UFO abduction, I guess. You wouldn't know it's so bad to look at her, but the result of the test showed an awful lot of things going on in the upper field that she didn't see at all.
Supposedly it's fixed with a pretty simple operation (blepharoplasty) by the right doctor. I hope it all goes well. She's a good-looking lady and she needs to be good at looking too. And to not be abducted by aliens.

You look better without my glasses.

Snellen, you magnificent B A S T...
I like my eye doctor, and my vision is healthy, and his office is pleasant, and I don't need new glasses so it's not very expensive, but I always go for an exam with a little trepidation. Could it be the terrifying brochures?
Could it be the horrifying Jack Kirbyesque exam equipment?
Or is it that puff of air for the glaucoma exam that you know is coming and you know is coming and this time you are NOT going to blink you're NOT you're AUGH I BLINKED
No, I think it's that I always feel like I'm failing when I get whipped by the Snellen Chart.
Herman Snellen of the Netherlands was not the first to come up with standardized charts to test visual acuity, but his (begun c. 1860) have been the most enduring. In America, we're used to seeing (or at least seeing part of!) this:
My doctor, like most these days, uses letters displayed on a screen at different sizes for the test, but it's still Snellen through and through.
This terror of mine goes back to my days as a student, when I was alternately smart and well-prepared or lazy and clueless---either way, I hated to fail a test.
At first the questions are easy: "E! F! P! Oh, this is a cinch! Gonna ace this one."
But then it gets tricky: "D... E... uh, F? P... O..."
And then you hit the rough sledding: "F... uh.... B? No, D! No, B! Wait--- DAMMIT! B! F, definitely F, unless it's P. (They wouldn't do an F again so quickly, would they?) L... T... um, O? C? O or C? Close enough? Are there any essay questions?"
Like a video game with ever-more-difficult boards, eventually you're going to fail. You just hope not to fail quickly. It's very discouraging, and leaves me feeling doomed.
