Earlier this year I went through a debacle with progressive lenses. Two different doctors and labs. It wasn’t a problem with getting used to them, it’s just that nowhere in my view was in focus. It didn’t matter how I moved my head. There was no part of my vision that was sharp. So they convinced me to just go with single-vision lenses. They came in today. Same issue. My vision is not sharp wearing them. I can put on my old glasses and everything is sharp and clear. So I’m just wasting money on eye exams and a whole lot of time. It’s been since last December for the first doctor.

Can they just measure my old lenses and replicate them? Something is really wrong here with two doctor screwing up and trying multiple times each. Did something change in the optometry field since 2017 when I got my previous prescription?

I'm not sure what they are screwing up, but they can definitely check your old prescription in a lensometer, and they can mark them and measure the pupillary distance of your old glasses. They should be able to replicate them without issue.

The only issue I could see is if your old glasses Rx is out of date and they want to use your new Rx which isn't working for you.

Yeah, that’s just it. They won’t make glasses with my old prescription because it expired. Now I’m thinking progressives may have worked had the prescription been correct. But how do two different doctors both get it wrong? I think I’m going to return these new glasses tomorrow.

Get a copy of your old prescription that works from whoever did the exam and try ordering from someplace like Zenni. Just input the old prescription info.

Unfortunately, that doctor passed away and the records are no longer available. I did get the prescription filled at Sam’s Club so maybe they have the old prescription. I’ll call them next. I hope they didn’t over write the prescription with the new one as that’s where I went last December.

They should have your old prescription as well as your new one. Whoever your current doctor is, he should be able to listen to your concerns and work with you on your prescription, so if your old prescription is working better for you he should be hearing that and either prescribing it again so it’s current, or looking closer at it to see what worked there that isn’t working with this new one and merging them.

If I'm a betting man, the problem is that your lenses are NOT being ground properly. It's extremely unlikely that the Eye Dr./Optometrist could completely screw up your prescription. You were there, and presumably arrived at a lens prescription that resulted in the clearest vision. At that point, all they needed to do was write it down correctly. Assuming your eyes weren't EXTREMELY tired at the time, that prescription 'should' be correct. This leaves the Optician that fits the eyeglasses, and an EXTREMELY important part of the process is measuring the PD (Pupillary Distance). You 'may' have a Dual PD where your pupils are not the exact same distance from the bridge of your nose. Additionally, it possible that your don't wear the eyeglasses with the pupil(s) exactly centered behind the lens(es), such that they're a little high, a little low, or possible a little of both. Though it seems rather rudimentary and imprecise, a skilled Optician usually has you try on the new frames and marks the center of each pupil on the faux lenses with a sharpie, and then takes critical measurements based on your actual pupil location(s) behind the lenses. Done correctly (no parallax error when they marked the pupil location on the lenses), your lenses will be ground such that when they're in the frame and you're wearing the eyeglasses, your pupils will be located precisely behind the position/center the lenses are ground for.

While there are a thousand different grinds for Progressive Lenses (due to the three different focal lengths), Single-vision Lenses are just that, so they should be able to get you eyeglasses that work for you. If they're wrong, somethings not right. I believe you NEED to find a competent Optician.

FWIW, I had a pair made by Sam's club a few years back and they were never as sharp as what I have gotten from a local shop. YMMV but I gave up on Sam's after the second remake. The local shop is more expensive, but worth it to me for the quality.

The last time I got my prescription updated, the doctor did the exam correctly and came up with the right numbers, but when his staff passed it on to the lens shop they transposed a couple of numbers. What I got back was completely wrong for me. They figured it out and redid them and everything was fine then.

Are the lenses being made with the same material with the same coatings as the old ones?

I had to have my latest pair of glasses remade 3 times! One of the lenses was off just as you described. this was a local shop also, not costco who I used until they changed their lens material to a shit product.
Have them remade, hopefully that fixes it.

These are great!

It's probably already been said in this thread, if it's been six years since you had glasses made, you absolutely need to see an optometrist and get an eye exam and be refracted while your eyes are dilated.

Your eyes change over time, and in my opinion, it would be foolish to try to get new glasses based upon a six year old prescription. You might be OK doing this, but you probably won't.

Take it from someone who spent a couple of decades dealing with the human eye.

I went through a debacle in 2019 when I got my first progressives. Multiple prescriptions, all different than what I was wearing that I knew had worked for 8 years or so. I had the Rx paper, but it was expired. First Rx wasn't too bad, very similar, but then the glasses weren't right and the company doctor (at company med center) and and company-approved Rx safety glasses shop blamed each other. I went to another doc and he was so far off on my right eye that the lens caused pain like my eyeball was twisting

Biggest issue is getting frames adjusted properly, then finding the pupillary centers and getting the lens ground to the pupillary center. Every shop finds the pupillary center differently. Some just have you look through a viewmaster kind of thing, others hold a ruler up to your face, and some dot the lenses with a marker. Once I realized there was no "standard" for this I was truly shocked. And when I finally got a pair that were prescribed, measured, and ground right, the stupid store guy picked up the frames and started bending on the nose pads before final fit check. Damn idiot, they should have been fine as adjusted in the initial fitting, but you don't start adjusting without checking first!

Lens Crafters and some other Luxottica brands use a fancy jig they put on the frames and then take photo with an iPad. Lens Crafters sells "precision" but the jig adds weight to the frames and makes them sit lower, and the lens on an iPad is in the corner and they almost always take the photo obliquely causing parallax issues with the pupillary centers. I pointed this out and they had no idea what I was talking about. I actually calculated the parallax from the distance between the ipad and my eye, and how off center and high the lens was, and it was significant. Indiana does not require licensed opticians, only that there is one in the store supervising the others.

Traditional progressives have a narrow center channel so try getting some that have a wider channel. Or try lined bifocals, but they are not so good for computer monitor distances. What ended up working for me was under-correcting my nearsightedness by 0.50 (so like -2.75 instead of -3.25). This allowed me much more useable area of the upper part of the lens at computer monitor distances, and I can still read a 20/20 chart. But I think I will go back to the "proper" Rx next time.

I’m currently dealing with a similar issue, that is, new glasses not working as they should. I have a pair of glasses that I ordered from Zenni back in February, which are great. I just ordered another pair, this time with a more sturdy, safety glasses like frame, but with the same current prescription. The new glasses came in and were absolutely unusable. Within minutes I felt motion sick and had a headache. Anything slightly off center appeared distorted. I returned them for inspection and am waiting to hear back from them. If they’ll remake them, great. If not, I’ll get my omega back and look into getting glasses made somewhere else.

Some folks just can't acclimate to progressives, others can put them on and adapt immediately, some just have to put in the time to get used to them.

Hard to say what's incorrect, maybe you are not really getting the correct information to them ie when they do the eye test, you see it one way, but the numbers don't translate to production lens.

Your doc should have the old and new script and be able to see what the difference is, I got mine done a few months ago, slight change in my reading vision, which I knew was happening, and finding the cataract in my left eye was the cause of slight blurryness at times, more like it makes it look as if the lens has a smudge sometimes.

So far that script has worked, the old one was 5 years or more old, but again, same doc shop same doc and they had the old script.

You might be better of finding a shop that uses Varilux or Essilor lens, they are two of the highest level lens you can get, believe Wal-Mart sells Varilux, Costco, Sams do not.

That’s just it. I’ve been to two different optometrists this year. Neither have prescribed lenses that are as clear as the 6 year old glasses. I’m wondering if something has changed in optometry, a new philosophy or technique? Differences in calibrations of the equipment? I’m just nonplussed why they can’t get it correct.

<<--< You've tried the rest; now try the best!



Seriously, you've gotten a lot of good information and suggestions in this thread. Speaking for myself, when I see people with the same concerns you have, I don't even want to see what has been done before-I start from scratch. (I have staff collect prior data if possible, but for the purpose of comparison only *after* I've done my work).

With the difficulties you've been having, the first step is absolutely having someone take the time to get the refraction dead on-this may most likely mean extra time spent with the optometrist-doing the refraction only, but then returning at a later date to assess the eyes in totality. This requires *you* to be very clear up front that your reason for the visit is *solely* to get a pair of glasses that you can see with.

And by the way-an eye doctor can neutralize your "archaic" glasses that you like, and write you that Rx-after examining your eyes if, in their judgement, that would be the best option for you.

Other things I would check would be the lens material being used (I avoid polycarbonate lenses); without knowing your Rx I couldn't say if you would benefit from more premium materials. As mentioned above correct pupillary measurement and correct placement of the lens in the frame; the MRP (how high the lens is positioned in the frame); making the measurements with the actual frame on your face already adjusted for faceform, cant and position on the nose. More esoteric things to check are tolerance to astigmatism power and orientation; tolerance to "balancing" the power of the lenses; the possibility of aniseikonia-among other things.

There really is a lot that goes into successful eyeglass production; the profession tries to make it look easy so you don't have to worry about all the behind-the-scene activity.

I'm not aware of any available technology that has changed the refraction process to any significant extent.

New information. If I lift the temples off of my ears and it tilts the top of the lens away from my eyebrows it seems clearer.

An optician can adjust your glasses
