Hello Mr. John. It's been 6 years since I have been watching your videos. Recently I passed ABOC this May and NCLEC just last Friday. Since I work in the Optical department of retail I need to learn, and you have all material that we need. I like your funny acting and clips from movies in the videos. Thank you so much.

Hello Prof. Siegel! Can you please make a video on how to change the ink for markings the lens when we do neutralize or do inspection?

Hello I’ve been following the channel for quite some time now. You’re doing a great job. I would like to know where do you suggest I position a bifocal lens in the lensometer to read the distance power.

@LaramyKOptical 4 жыл бұрын

Distance is usually found about 5 mm up and 5 mm over from the center of the top of the segment. The optics get kind of messy so you may need to move around a little. Your segment to segment check will tell you if your near PD is correct. You could work from there I suppose. If you always work with the same lab I'd ask them what their default height is in relation to the segment top. The distance PD should match the customer PD so that will move around a little. John

Laramy-K Optical thank you so much. I don’t know if you know anyone who took the ncsorb simulated practical exam on the computer and they always have an issue neutralize the bifocal by not properly positioned the lens to read the distance power

Hello, I am not new to optical but I'm new to the lensometer and especially reading prism so I apologize if this is a dumb question.... If you adjust the PCD (never done that before) while neutralizing glasses will you still be able to tell if they have a prism correction?

Do you have any videos on verifying an indoor variable AKA computer progressive lens? I know that there’s a digression (or is it degression?) and you have to know the total power. Should you start reading the lens at the bottom first? Thanks for any information.

@LaramyKOptical Жыл бұрын

For verification/final inspection no reason to treat it much different than a traditional progressive. You'll have laser etchings and/or paint marks from the lab. Your "distance" circle will be the power for whatever the lab says it should be for that design. [what you chose the lens to be for] You will struggle if you are trying to "neutralize" an unknown office design. I'd find the marks, figure out who makes the lens and work from there. You would never try to read the "bottom" on a progressive design. Any add powers on a progressive are read from the etchings. Honestly I'd check with the lab and if it is a free-form you should be getting a ticket with the compensated powers. If it is free-form and everything looks right for heights etc and you can get kinda-close to what you would expect in the lensmeter you have to trust the lab. If it is not a free-form and everything looks right for heights etc and you can get very-close to what you would expect in the lensmeter you have to trust the lab. I'd lean towards if everything looks right and you can get somewhere in the neighborhood of what you expect let the customer try them on! If you need more email me through the OpticianWorks website and I'll bounce this off IOT. John

Question: I am extremely new to being an optical assistant and "learning on the job" however my "mentor" aka my boss is not quite clear on alot of things, thus leaving me to dig for ny own answers. So here is my question: when verifying progressives in the lensometer, you have your "distance dot" point centered in the eye piece. When you turn the dials to bring through clear sphere and cylinder lines....its never centered. Now I was told tha the higher the RX, the further away it will be centered. Does that mean this lens has a prism?

Please get a membership to the OpticianWorks program. You are the very type of person it was created for. Sounds like you are under a lot of pressure and not being given the time or tools needed to do your job correctly. The answers to your questions are in the video, in some of the other videos and on the website. You'll just need to find the time to watch and read. FWIW it sounds like you may need to talk with your employer or start looking for another place. Opticianry isn't rocket science but there is quite a lot to know that you can't just "pick up on the job" and no way to do it without some good coaching. John

Is reading a progressive the same across the board with all PALS? (I.e standard,premium progressive, digital)? Do you always read PD’s and seg ht from the dimple you create from the layout chart? Will it ever shift left or right past the distance circle to read the pd?? I hope this question make sense lol

@LaramyKOptical 3 жыл бұрын

All your work on a progressive is from the fitting cross. Yes, you recreate it (and your 0-180 alignment/reference points) using the chart. Prism if required you check at the PRP which is usually a little under the fitting cross. So PD and fitting height are measured from the fitting cross which can't "move."

Hello, I would like to ask if I wanted to check the near add for the progressive lens using the lensometer would I position the frame so the arms are facing away from me or towards me?

@LaramyKOptical 3 жыл бұрын

You don't check an add that way on a progressive. And no if you did - which you won't - you wouldn't reverse them.

What if the customer's old glasses are seriously scratched, how can I find the mark? Is there any better way to find out?

Ken, The laser engravings are pretty tough. A PAL tool is a huge help as is a very bright light against a black background. As we age they get harder and harder to see. Drop me an email and I'll send you a picture of the inspection boxes we use at the lab. johnseegers@laramyk dot com. John

Prism Reference Point in the lensmeter and WYSIWYG. Until you get outside the range of the reticle rings and then you are out of luck.

Lensometer

The true correct name is actually a focimeter. Lens-O-Meter is actually a specific brand name for the tool. Always thought it was kind of silly myself.
