Chris, If you go to the main VIDEO page they actually appear in the order they were posted. Last one posted first, first one ever posted last. Or at least that is how it works on my end. John
Only if the lensmeter is actually in need of calibration and that requires special tools/talents. None for individual differences that is YOU not the lensmeter.
John, you mentioned both the gimbal and rubber lens stop can both be replaced. Can you provide me with information on where to purchase these replacements? Thank you!
You should be able to buy them directly from Marco. If you are placing an order may as well do the pen upgrade/update as well. If not Marco try J A Optronics out of MD. John
Depending on what is wrong you can replace the single screw gimbal or the whole double screw arm/mount and gimbal. Marco should have parts available and hopefully a parts schematic or advice on exactly what you need. Depending on where you are you might try J A Optronics out of MD. Let me know how you make out.
Hi, I have attended a ODD program and the school had this version of a lensometer however my employer does not have the most updated equipment. Would it be possible for you to provide proper usage of lensometers where prism ring discs are required when needing to verify prism amounts on a older model lensometer? Love all your videos! I used them frequently while in the ODD program still today as a LO when needing refreshers! Thanks so much!
Yes & No. Yes: Basic prism rings are actually easier to use than a PCD. If you are trying to read a progressive and the target is displaced just try your different strength rings until you find the one that lets you rotate the target to where you need it. Generally you have the little black-box with 4, 5, 6 rings in it. No: I have extending prism using the PCD (or rings) on my shoot list but until I can find someone to loan me a high-end auto-lensmeter I can't really finish it. I really can't find anyone to explain it/demonstrate it to me and I simply haven't done it enough to be able to teach it. If I had a good auto to "double-check" things then I would feel confident trying to pass it on. I have the lenses here but no auto-lensmeter. And - That sort of thing really falls on specialty labs and places that do low-vision or specialty vision. John
Hi. Love your videos! Wondering if you can tell me where to find a tech manual for a Marco lensometer. I just acquired an old one and it needs some love. I am technically capable and can work with a real manual. Thanks is advance.
An actual repair manual - no sorry. I'd ask around over on OptiBoard. But - most people just take them apart and put them back together again. There is a company J A Optronics out of MD that has parts and service as does Marco. You'll want a few GLASS higher power stock lenses like a +4.00, +3.00 and something with around 1.50 cylinder for calibration. There used to be a tool for it but only a few survive.
Hi John, quick question: what is the lifespan of these beasts? Ours is 20 years old and I’m about to send it in for calibration/tune-up. I don’t want to buy a new one if nothing is wrong with this one (Same model,) although our Marco representative has already mentioned it’s age. I believe they just want to sell me a new one. 😂
Very, very long! If you send it off to Marco for a refurbishment you should buy yourself another 10+ years at least. You can take care of routine maintenance (pens-ink and lens stop ring) yourself after that. Thing is the new ones have superior marking pens, LED light and battery power. Old models can usually be retrofitted with new pens, LED bulb is nice, batteries - eh you just forget and leave it on and run them down. (The new pens are really great but stupid pricy)
Old lensmeters have either an ink pad or an ink roller. New ones you have to actually replace the pens. A bit pricy but nice when they are new/fresh. Assuming a Marco you can buy them from them. John
Your refractive error can be corrected when using the eye piece to view the reticle so no need to use glasses although you can, it would just be better without it
LMAO that glove caught me off guard
Me too, I was tripping
Love the series but would like to see you guys number them so we know which order they should be viewed in.
Ah, see Chris, but that's how we get you. You need to join OpticianWorks to get them all in order and in context. Thanks for watching! ;)

i really appreciate you doing a video like this i've subscribed and i will be sharing thanks again we needed this (y)
Thanks so much, Wynton. We appreciate your comments and your shares!
You really have Vince's body language down pat!
Thank you so much!!! I have learned so much from you.
6:54 Is there an adjustment on the power drum index to compensate for the amount that is off?

Omg! I used to love that commercial!
That was so long ago I had stop and think which commercial! That was a fun one to make.
This detail helps !! Thanks
fun and informative lecture
👏👍🌿
Thanks again, Yasa. Glad you enjoyed it.

Did anyone noticed that green colored hand? What was that man!!!!! :)
:)
Gojira!!!!
Great intro!! Makes it interesting
How do you change the gimbal? We need to change one at my store!

Laramy-K Optical hi, thanks for the info appreciate the swift response! Be safe, be well!
The Lensmeter playlist has the videos out of order. This is the first video but it is the third video on the Lensmeter playlist.

Laramy-K Optical thanks for the lead. Found a service manual for a B&L but Marcos are not too easy to find. Keep the videos coming!

Thank you!
excellent video Opticianworks Rules ! Are you hiring??
Thanks! You can always check with the lab on hiring. John
Thank you ♥️♥️ you’re perfect 👌
Great sir
This is gonna sound dumb but how do you refill the markies? I've got the ink but I don't see a slot haha

thank you
Thank YOU, Default! ;)
😂😂😂 the intro
The sequence in the playlist is wrong. This one (#3) is actually first.
😂you are the best thanks
Eyecup lmao he said that and i thought "i c u p" aka i see you pee lmao hi I'm 12
EWachob Ha! Same. I literally came to the comments to see if someone thought the same thing.
I couldn't get the steps in clear order..
may I ask for literature ?:)
I wear glasses, can I not wear them when using this machine?
90's, You need to try it glasses on and glasses off and see which gives you the more accurate results. Just focus for each and experiment. John
U can, it's about setting your eyepiece.
Your refractive error can be corrected when using the eye piece to view the reticle so no need to use glasses although you can, it would just be better without it
All I can say is, "WOW!"
Is that for Wonderful Optical World? John
The Shamwow! was really entertaining.
Found the manual at : opticianworks.com/wp-content/uploads/2015/10/LM-101-1021.pdf
That is an excellent place to look! ;-)
