Respectfully, I’m not sure you are acquainted with the underlying theory for these tolerances by Darryl Meister and Dick Whitney. Further, no subjective exam modality and its accompanying “precription” warrants slavish devotion to any standards.Originally Posted by lensmanmd

Is "eh, good enough" their mantra as well?
Good enough is a value appraisal.

Compromise lens coatings.
Compromise lens materials.
Compromise frame quality.
Compromise style.
Don't compromise vision unnecessarily.
Yes, we compromise vision for progressive optics.
Yes, we compromise vision for cosmetically thinner/lighter lenses.
But it's a matter of a controlled compromise...a judicious decision is made to give the best of all factors.
"Oh, but I'm adding low cost into the compromise". Well, you don't have to...CR39 works wonders.
"Oh, but I'm adding convenience into the compromise". Get off your fat *** and come into the optical.
Agreed, drk.
............................and is still the best and most workable lens material on the market.
It is obtuse to pretend that all patients want the highest standard of quality. I would wager MOST want just 'good', not excellent. Especially when they never have to opportunity to do a side by side performance comparison. Especially when most opticians can't explain the functional difference between a 150.00 progressive and a 400.00 progressive. And especially when the increase in quality and performance doesn't match the increase in price.
Yeah, but that's not what we're talking about.
We're talking about not taking biometric measurements, not seeing the patient in person, not doing a history, not taking physical possession of the prescription, not selecting the frame, not taking seg heights, possibly letting the patient choose the material as well...
...what a disaster.
I usually don't know what people are talking about.

Are we going to see BarrySantini.com or not? Is that what we're building up to?
Look people, in an age where you can decide whether you're a boy or a girl and can live in your own virtual reality and you can have "Your Truth" and you can have Amazon Prime deliver to your doorstop a bathrobe for $2.49 in 24.9 hours, I "get it" that I-want-what-I-what-when-I-want-it is the new normal.
But reality exists. Grown ups live in reality. You can't have everything you want. Sorry.
Perhaps it’s time then for optical businesses to embrace the gray area in returns and repurpose it to increase customer satisfaction, loyalty and repeat business....Mostly, try not to make your quest for perfect eyewear the enemy of making it good enough. And remember, all value approximations are, at their core, individual perspectives on what’s good enough in the eye of the beholder.
OR:
“Without the ability to use a pen, ruler, eye and ear to directly assess physical measurements and evaluate the look, feel and fit of a frame and discover the buyer’s individual needs, wants, desires and expectations, there’s no way you can truly make a great pair of eyewear.”
Important words for all: Truly understanding what makes good enough good enough.

I will ponder that riddle, Barry, for a long time.
Hoid is former King Elhokar's Wit and entertainer. He is a recurring mysterious character in the cosmere.
According to the Vision Council of America, ........................
According to the Vision Council of America,
approximately 75% of adults use some sort of vision correction.
About 64% of them wear eyeglasses, and about 11% wear contact lenses, either exclusively, or with glasses.
Over half of all women and about 42% of men wear glasses.
Follow up to my Invisible Man piece:
Tonite a previous client came back to my office. Had ordered their latest Rx inAR coated progressives from Eyebuydirect. Total cost was $89 for one pair, with an incentive to buy two for a total of $150.00, so they did.
Both zyl frames, one pair broke at the bridge in less than three days while cleaning: “They were so tough to clean and ‘rough’ to wipe I broke the frame while trying to clean the lenses.” I asked: “Did you exclaim SHEET?” “Yes!” Was their response.
The other pair faired better, but they thought the progressive was too high. I marked them up and found the PD accurate to 1mm. They had their order confirmation printed out, so I asked to see it. While their PD, measured by me, was 57, the order listed 59 as the value. I asked “How did you arrive at this value? Did you or they measure it?”
”No” was their response. “I just choose 59 from a drop-down menu because it ‘seemed about right’.” Tbe glasses actually finalled at 58mm, so close enough, yes?
Bigger problem was the finished Height. The circles/cross height was, assuming a 4mm drop, were 3mm above their pupil, so no bueno. I decided to perform an invisible man calc on the blind height, and found the finished height was more than 6mm above the frame’s Mid B. If these had been made using my calcs from the article, they would’ve been fine (3mm-4mm above Mid B, less 1mm).
We picked out a new frame, and I carefully measured the new height. Surprise! Their pupil turned out to be 4mm above the new frame’s Mid B. And I still subtracted 1mm for my ordered fitting height because they asked “to make sure the progressive is not too high...maybe even a little lower, please.” “And do you have an anti-glare that is smoother and easier to clean?”
Between the too-high height and the rough, low grade AR, someone has been suffering.
The new eyewear came to $600.00. Paid in full at time of order and accompanied by a loud “Thank you!”
Invisibility comes with a cost if you don’t know what you’re doing.

Two pairs of nicely working glasses would have cost the patient 2 x $ 600.00 = 1200.00.
So that would have been $1,050.00 more for the 2 pairs purchased online.
Interesting…………and good income if you know what you are doing.
Then our websites for ordering glasses will be better than their websites for ordering glasses.
Thanks for the formulas!
Barry. Your formula for height has been around for quite a while. Check almost any cast PAL semi-finish blank....The fitting cross is almost always 4mm above geo-center. Most all cast FT semi-finish bifocal blanks are 6mm below....
I've read your article twice now. No offence, but you, at times, have a cryptic writing style. I honestly still don't know the exact message you were trying to convey, even with what you've written in this thread...
Are we (as ECP's) to shoot for mediocrity? "Good enough" for perceived "value"? That we will ALL (B&M's) be selling glasses online, so just shoot for averages?...
What I hope you were trying to get across is that meeting a patients "perceived value" is more than about price alone. That atmosphere, great products, precision and friendly, knowledgeable service all contribute toward the "perceived value" B&M's can offer that no online entity can. We need to become a looked forward to "destination" for products and services patients and clients want, not a dreaded place they need to go to.
Yes. Value and understanding that fine specific measurements are not nevessary to acheive an adequate result which will satisfy both current industry standards AND VALUE CONSCIOUS BUYERS 80-85% of the time.
And the awareness that hard skills are being surpassed by technology so the whole ownership experience is what matters going forward.

Sorry, lost me again Barry. Did you just say:
A. Shoot for adequate instead of excellence?
B. If you have an average demographic, be happy with satisfying 80% of them rather than trying for 100% because 100% isn't possible?
C. That hard skills won't be needed soon because AI will be able to trouble shoot 80-85% of issues that arise from bad refractions/fits/designs/measurements/ect?
D. That I need to put a keg in my dispensary and have a block party daily? (or just medicate myself daily and await my rapidly approaching retirement?)
