I'm having trouble getting my latest progressive lenses made to my satisfaction. Allow me to tell my tale of woe....

I always have to go with the cheapest progressive lens option, which of course is asking for trouble. But in 2011 I had a pair made that worked out pretty well; i'm still wearing them. The other week I went in for my eye exam and the optometrist wrote me a revised prescription.

OK, so I get a new pair of glasses made -- and they don't work; everything is kind of blurry and eye-straining. I take them to the optometrist, who tells me that the lenses are way off from her prescription. She tells me to have them remade, and to ask the opticians to check the glasses with their machine, which is apparently much more accurate than hers. She also re-tests my eyes and decides to make one small change to the prescription.

I take the glasses, and my new prescription, to the opticians, who check them and say no, these glasses are dead-on. But they remake them anyway to add the small change to the prescription. the glasses are much better now -- but they still aren't quite right. Depth perception seems exaggerated, and printed words on highly contrasted backgrounds show a bit of ghosting or "ringing" around the edges. My right eye also seems less well corrected than my left eye; this may well be the root of the problem.

For you optometry students out there, this is how the prescriptions compare:

(OLD)
OD: Sphere -1.25; Cyl -2.25; Axis 035
OS: Sphere -1.50; Cyl -2.00; Axis 155

(NEW)
OD: Sphere -0.50; Cyl -2.25; Axis 046
OS: Sphere -1.25; Cyl -2.00; Axis 150

The biggest difference is obviously the right-eye's cylinder. it seems like an error, considering how little everything else has changes, but the optometrist checked these numbers twice, and the only change she made was to reduce the right-eye Cylinder to 2.00. (That's the change that seems to have helped some, but not quite enough.)

Anybody have any thoughts on this at all? I have a feeling i'll just keep going back, getting the same numbers (more or less) from the optometrist, and getting the same "We ground them perfectly, don't look at us" from the optician. I've already shot my annual vision insurance wad on these folks, so I guess I'm stuck with trying to make them get it right instead of shelling out of my pocket to start the whole process over again with somebody else....

If I'm still seeing clearly out of my 2011 glasses, should I just admit defeat and keep on wearing them?

In a coffee shop.
I have worn spectacles since I was seven years old, and was diagnosed as requiring them; naturally, decades later, I still wear them, a situation which leaves me interested, and a bit informed about the lives and needs of spectacle wearers.

The first point I wish to make is that while money & finances may be limited, even within such constraints choices can be made. Yes, I can be a bit profligate with money (especially when I have it), and yes, I am rather partial to the good things in life.

However, there are some areas of expenditure on which I would never compromise quality in order to save money, whereas the purchase of the sort of consumer goods I really rather like (say, Apple computers, iPods, Bowers & Wilkins headphones), can actually be postponed or deferred. Anything to do with my eyes is something I regard as a fundamental, core, non-negotiable source of expenditure.

The point is that I would never, ever compromise on cost where my eyes are concerned, and I note from your post that you have done so. Eyesight is vital, and for me, it is imperative that I trust, respect and rate the quality of work and the judgement of whatever eye specialist I attend, and, moreover, that anything and everything to do with lenses is done to the highest of standards. To compromise on expenditure where your eyes are concerned is - to my mind - something of a false saving.

Would you consider getting a second opinion from a separate source on whether these lenses have been made to the standards and precision required? I would recommend getting an alternative opinion; I would also recommend that you reconsider your attitude on always going for the 'cheapest progressive lens', (by way of contrast, even when I worked as a fairly poorly paid teacher, I always requested the very best possible lens, and worked out a way to pay for it, usually by foregoing or tweaking expenditure elsewhere) and choose to make savings elsewhere in your world. And yes, I would suggest approaching your insurance company; if they do not foot the entire bill, they may consider funding a percentage, and, perhaps, you can suggest that option.

Meanwhile, good luck with it.

I'm no optometrist, but your description doesn't match anything about those prescriptions.

First, the biggest difference is in the right-eye's Sphere, not its Cylinder (O.D. is right eye). Second, it wasn't reduced to -2.00, it was reduced to -0.50. The left-eye Cylinder was reduced from -1.50 to -1.25, which is the only thing I'd call a "small change". There was also a right-eye Axis change, from 035 to 046, which (if I interpret it correctly) is measured in degrees, and a 10 degree change might well be noticeable.

I used this to decipher the terminology:

Sorry, I was saying "Cylinder" when I meant "Sphere."

Just have them use the 2011 prescription!

I'm seriously considering doing that. After all, vision testing is based on the patient's subjective opinions -- "better like this, or better like this?" If my 2011 prescription is correcting my vision accepting without causing eyestrain, there's no law that says I have to switch to another one....

Exactly! If it works it works
