Hey All - John here. I see this video is getting plenty of views while Part II and Part III are not. Those are actually the important ones! Don't stop here! Let's see the view numbers grow on those too (or two as you wish).
Kinda miss this work, did it for many years. Very satisfying
Thank you for your precious videos! I'm trying to make a work visa for Canada and your videos are training me to use English technical terms.. and in the meantime, I learn... Thank you
You're awesome!
Hey John, I was taught to check the alignment of the bifocals, PAL’s with the frames upside down with the top of the frame faced down and the front of the frame facing me. Is this correct? Love your videos!
Upside down? Um, no just no. WTH? Lined bifocal facing opposite yeah sure after checking distance as usual. PALS no. PALs are not working off front vertex power where the SEGMENT of a lined bifocal is. [insert banging head against brick wall emoticon here] ;-) John
Dear Sir,
Please make a Video on 'A to Z of ALL Types of Glasses'...
Really interesting and informative as usual. Great videos.
Just a question about the Panto which seems a relative measurment to do a quality check.
Optometrists usually consider Panto as POW measurment. Then, will that be correct to use any measuring tool for the frame and the ordered Panto during the final check at lab?!
Mahesh, I'm not sure what you are asking? To have it matter you would need to have the panto angle from the very start and provide it to the lab as part of POW measurements. In general, day-to-day, SV stuff every frame should have just a little panto for the lens to work best but that can be added at any time.
@@LaramyKOptical I was not asking about the general panto if it is being added to SV lenses. But it was about the Panto measured and given to the lab bases on PoW for a lens design which need PoW parameters.
Hi John, thank you for making this video. I'm confused where the segment height starts on the lens. Is it where the progressive trademark Or the prism reference point?
A progressive fitting height is checked at the fitting cross. If the lens doesn't come back from the lab with its original paint markings you need to recreate them with the matching chart. Different designs have different distances between the 180 trademark orientation "line" and the cross. If you need more email me please.
Can you go through the verification part for a bifocal and trifocal? Where I work I do a lot of them just because of clientele is a little bit more on the traditional side
Look way back at the series on the lensmeter it is covered there. John
what brand lensometer you are using and what model? using manual lensometer is good or auto would be better ? what do you recommend ?
That would be a new Marco 101. If I had a choice I would use a high-end auto but no one seems to be willing to give me one... Manual work just fine.
John, where does one acquire the panto / wrap verification sheet?
Drop me an email through the OpticianWorks website.
Hi Mr John,
Hope you are having a good day
May I know would you be do a video on transition lenses and photochomic lenses differences? Appreciate much
Jonathan
They are the same thing. Transitions is just a brand name for a photochromic lens. How and why a lens changes from light to dark varies depending on film technology or in-monomer chemicals. Most manufacturers have offerings in both. Photochromic has become a catch phrase for any lens that has a reaction to light. Perhaps it isn't 100% scientifically accurate but works for our purposes.
@@LaramyKOptical appreciate much for the explanation and prompt replies :)
Is the checklist available to print off? Or do you need to be registered for the training?
Drop me an email through the website and I'll send you one later this week. John
Can you please send me this QC Format
Sir,pls make some video about the lap tool calculation.
Working on that now oddly enough... but like every subject here I thought we would just touch on it - BUT - one thing leads to another which leads to...
Thank you. Quick question. I ordered lenses from an online retailer. Hi-index, with standard anti-reflective coating. When I tilt the lenses under light, I see one lens has a green hue, while the other has a purple/pink hue. Is that normal? If not, what would cause that?
Sounds like lenses from two different manufacturers. Not unheard of but certainly unusual. Very slight chance it is a matter of lens position in relation to the other - but I doubt that is it. Mostly a cosmetic thing.
@@LaramyKOptical Thanks. I talked to the retailer and they actually wanted to replace the lenses. I had some eye strain with them too. However, the new lenses are thicker though both are 1.74 high index. When I talked to them, they told me this “I spoke to my technician and yes, the lenses were still made in the 1.74 material. But the new lenses were made a bit thicker. My technician believed the issue was the stress the lenses had due to edging required(this had to do with the eye strain you experienced). So, to relieve the stress the lenses were made thicker. “ Does that make sense? I mean does the lens thickness or degree of edging have something to do with eye strain? Just curious..
I’m not going to replace the lenses again just for that.
@@DrGogu-yd6jc I'd strongly suggest getting your glasses from a different place next time. Sounds mostly like nonsense.
How do I know as a customer if my glasses have the Crizal coating I paid for? My lenses seem soft as butter and scratch very easily though they have a two year guarantee. thanks
Wow great question. I'm not an Essilor fan but a true Crizal coating should be some pretty tough stuff. Now every lab has a bad batch of AR once in awhile (see our video about testing ARs) but the only way to be 100% sure would be to ask to see the invoice for your job. They may well fight you every inch of the way but if you suspect an issue you'll need to press. Hope that helps. If you need more please move to email - thanks. John
@@LaramyKOptical Thank you very much for your reply, $700 for two pr. of just lenses soft as butter got me irked.
I ordered 2 pair of bifocals, and I don't remember the optometrist measuring my pupillary distance.
Assuming you were already wearing glasses they just use what they have and that is a good thing. Heights may vary - PDs don't.
@@LaramyKOptical My opthamologist updated my prescription after cataract surgery, I asked him what my PD was and he said the optometrist measures that for my new glasses, but the optometrist didn't use any scale against my eyes. I am not sure what I"ll get when my eyeglasses arrive.
Could be they used your measurements from you old RX if you got your previous glasses from them. Occasionally the Dr gives them the number too.
@@patkcorcoran The phoropter that thing they place in front of your eyes when doing the "which is better 1 or 2 thing" can read your PD. And - yep - PDs don't ever change even after cataract surgery. If it is written down somewhere in that office then no worries...
I wonder how many opticians are remotely this thorough. After 60 years of wearing glasses I'd say not too many.
Oh, I don't know. Everywhere I ever worked we certainly "checked in" every job that came back from outside the store. Big-box places to independent optometry shops. Did we catch everything? Nope. Did some people do a better job than others? Yep. Did we all have good days and bad days? Yep. But most places at least try. John
@@LaramyKOptical It could be that I have been unlucky or possibly this sort of thing varies from country to country. I'm in the UK, which you would imagine would be as good as anywhere, but a trip to an optician seems very much a lottery as to how well the end result will be if you require a new prescription, or even a re-make of an existing one.
Ha ha My High index, progressives/Transitions are back to the lab for the third time due to mistakes. 1st... wrong PD, then Wrong Rx, then lab forgot to use Transitions lenses. All I suspect were Store mistakes, but it was the consumer(myself), that noticed ALL these mistakes! Inspections were no done properly. 50 days in, and hope to get them correct by day 62.
And, I have real bad eyes...-8.50 rt. and -7.00 Lft.
And it's one, two, three strikes you're out in the old ball game... Think I'd find a new store.
@@LaramyKOptical I did, but waiting for the glasses to come back this 3rd. time . If not correct, I want my money! But That's how I work... 3 strikes, and you are gone! Funniest thing is, I got a pair of cheaper online for mowing, they are better made at less than half the price, received in 11 days from ordered, and hardly any adjustments needed!
How commonly do you see glasses come back from the lab with OD and OS reversed? That is, left Rx in right side and vice versa? This recently happened to me with a chain. Several opticians missed this, and had me return to be re-refracted (they only had me repeat the exam after breaking the temple during adjustment, since the glasses would need to be remade anyway). It's astonishing how many times they missed this reversal.
Needless to say I'll be visiting an independent shop in the future, insurance be damned.
Common? No, not at all. Does it happen? Sure. I can understand how it happens - I can't understand how an optician can miss it when RE-verifying the pair for a problem. Funny but that is actually a time when an optician LOVES to find a glaring mistake like that!
@@LaramyKOptical thanks for writing back. I really enjoy your channel, even though I'm not in the optical field.
The entire experience was terrible. It took a total of six visits and two refractions to get single vision glasses. The new, new pair they made had multiple chips on the eyewire and bridge, including one that appeared to have touch up paint. I finally have a properly adjusted pair of glasses, but it will be my last time going to a chain. Keep up the great videos.
Corn beef and cabbage
Here because my glasses had an axis manufacturing error lol
Trivex? Noooo!
Trivex. Yes???????
