Oh, also… did you check the date on the prescription?
That was during lockdown, they were super stupid strict about dealing with people then. They wanted to keep their distance and get people in and out as quickly as they could.
So I didn’t get my prescription paperwork until after they made my glasses. Corporate streamlining…
And now Walmart is shutting down all their health centers, ain’t that fantastic?..
In principle you should get retested but either way, you should be able to figure out your old prescription by measuring the focal lengths of your old lenses. I guess that could be hard for some exotic corrections but typically it’s not too bad.
Simplest case is you are farsighted. So your lenses are magnifiers. You move them away from a printed page til the magnification is at maximum. The distance to the page is the focal length. Diopter is 1/FL in meters, so eg. 50cm FL is 2.0 diopter. Negative diopters, astigmatism corrections etc are more complicated.
It looks like you can also test your own vision with a phone app and simple device:
Seems neat I guess. I just wonder why the hell I can’t just go in with my old prescription, tell them straight up that this is perfectly fine, I just need new lenses that ain’t all scratched up…
That’s easiest I guess. Just find out your prescription when you get tested. Yes a lot of the industry is bogus, but then a lot of the world in general is bogus. Part of being an independent and flexible person is being able to find ways around bogosity.
Doesn’t count after one year, they can’t give me the numbers after one year, by some stupid law they claim.
I have to have a new prescription for them to help me, despite the fact they literally know my prescription stays stable for at least 5 years.
That’s bullshit, but still…I meant, when you went to the doctor, you got the prescription, you looked at it, you couldn’t read it.
Why didn’t you ask?
You’re literally reading it. What’s a swapout Walmart employee supposed to make of this chicken scratch?
Dude, the guy who wrote it gave it to you at some point.
You took it, looked at it, and didn’t ask what it even means. So why didn’t you ask then?
I probably should have, but ya know what? My eyes were still adapting after the exam and I couldn’t fucking see to read.

They can’t legally measure my old old lenses. You know, the ones I tell them work the best?
Yeah, for ‘liability’ reasons, they can’t go by my 6 year old lenses, even though they’re the best I can see through, as a backup monocle…
You can do it yourself with a tape measure.
That’s gotta be the dumbest shit I’ve ever heard.
But sure, I’ll bite. How do you measure the exact curvature of a prescription lens with a tape measure?

Idk anything about that though.
