Hello Mr. Laramy, i want to let you know, that I'm an Optician, with many years of experience, but you know something, i like to wetch your videos, because, doen't matter how much it's your experience, always you can learn something, now I'm here to learn something, anything...Of course I know how to take measurements on pd's and segment highs, but I'm sure I'm going to learn something...thank you...

Luis, Everyone, every optician, has their strengths and their weaknesses. We can all learn new things or see better ways of doing something. Thanks for watching our videos. John

This was super helpful! Many of the patients I see still prefer bifocals, I have yet to see one that I have dispensed a trifocal too but not saying they aren't out there. Many can't adapt to a progressive lens no matter how low or high the quality of optics it has. It just depends on how their brain adapts to it. so Yes still dispensing lined bifocals is a thing because progressives aren't for everyone. No pair of eyes are the same as another pair of eyes. So thank you for this wonderful information of measuring :)

Whoa - THANKS! I love hearing from folks like you. So glad you found it helpful. John

I like to use a piece of tape when I measure my bifocals, just so my costumers get the FEEL of where the line could be at!

Thank you soo much Mr. L.K for your tuition.

thanks for your information, time and effort

I like the listening part. People have their preferences and also physical considerations (neck pain).

Thank you for this!!

Can I do 2 Lens and have different OC height for R and L? Only cosmeticd issue?

Hello sir, thank you so much for your information, I have a question: for round bifocal we have to use which pd distance or near?

I'd supply the lab with both and let them sort it out. For any segment style you should provide them with both a distance and a near. Different labs use different techniques for blocking layout. I've been searching for 10+ years for anyone that REALLY knows anything about round segments and have come up with nothing.

This was interesting. I am glad there are people still wearing lined bifocals. But you seem to suggest in one of the comments that lined trifocals stop being dispensed. I still wear lined trifocals and like them very much. It scares me that that they may one day no longer be an option. I have been considering asking my optometrist to try and compromise my reading distance by taking it out a little further to maybe find an middle ground between near and intermediate if trifocals vanish but I'm afraid I would have to hold things too far away when reading.

The use of lined trifocals is certainly in decline. The blanks used to create them are getting harder to get but they are still in use. Considering you are already wearing them that says something about your age - you'll probably live out your remaining years without a supply issue.

@@LaramyKOptical Thanks for the reply. I am 55 years old but my intermediate vision still needs help. I would move to a higher end progressive if I felt confident that I would have enough room to see consistently at one depth. By this I mean the my intermediate lens on my lined trifocals is a depth of 7 mm. When close to the eye that is a satisfactory amount of space and I know it will be consistent and dependable. But if progressives - if I understand them right - keep changing as you look vertically down the lense then it seems like it would not the same enough to take in very much vertical space. Does that make sense? What are people in need of intermediate vision to do if they don't handle progressives well?

@@goodwill6767 A shop should be willing to switch you back to a traditional lined style trifocal if a progressive is a non-adapt. It is an agreement between the labs and the progressive lens companies. Just make sure you have that agreement up front. You won't get back any difference but you won't be stuck either. Your eye/brain naturally finds what it needs for any given length in the progressive designs. BUT - if you are perfectly happy in a lined trifocal why fight it? Probably saving a few (maybe many) hundred dollars per pair as well! John

@@LaramyKOptical Yes, they did say they would change me back but without the difference if I couldn't adapt. I wouldn't even think of changing but if the blanks used to make them are getting harder to obtain eventually resulting in the death of trifocals then I though maybe I should cut to the chase and just try to make the change before that happens. On the other hand one would think they would be almost compelled to keep them if for no other reason than to have an alternative for those who simply cannot adapt to progressives.

I think fitting lined segmented lenses based on lids or irises is old and obsolete. I suggest taking a pupil height and then understanding that acceptable and satisfactory outcomes, aka 20/Happy, can lie within this range: Bifocals: 8mm to 10mm below pupil, with outliers in the 7mm to 12mm range Trifocals: 3mm to 7mm, with outliers in the 2mm to 9mm range.

Trifocals = Yes Bifocals = Heck no. I really couldn't disagree more. Progressives are NOT the answer to everything. It isn't about new, or modern or in the present it is about a lens combination that actually works very well for some things. I could wear any lens on the planet and when I wear glasses they are a lined bifocal. If more opticians thought beyond progressives as the default-go-to-lens-for-everything they would actually increase their value to the consumer. Don't let assumptions override possibilities. And not everyone has $500 or more to spend on a pair of glasses... but they still need distance and int/near. John

@@LaramyKOptical I just can’t understand why 99.9% of people can’t adapt to a modern progressive design. Even the cheaper designs work well enough. We’ll have to agree to disagree on this one. How many first time presbyope’s do you dispense bifocals to?

You are 100% right and you are correct in thinking that progressives are the lens of choice in the world today. But I really hate the "stop dispensing them - relics of the past" way of thinking. They have their place and if we leave the door open we have more choices or more tools in our toolbox to make a customer happy. I don't like newbies never even considering them as a choice when we use language like that. John
