Join us as we dive into progressive lens to help everyone understands what goes into the lens.
Today we talk about digital vs conventional, understanding how we manufacture them, as well as highlight the benefits of a digital lens over a conventional.

Even as a veteran of almost 30 years in the optical business you are never too old to keep learning, and stay on top of the latest lab technology. This is a very good, informative video. Good job. Keep them coming.

Very informative. I'm a long time eyeglass wearer (42 years) and when I was in my early 40s, started wearing progressive lenses. It's come a long way with the more recent manufacturing processes.

This guy is so passionate about making lenses and informative about how the tech actually works. I am kinda stoked to get my new digital progressives now. I was a bit skeptical at first.

Why does every video on KZfaq have annoying constantly playing music in the background that drowns out what the person is saying? Stop this trend please.

Still need the general results / specs though - and a visual comparison wouldn't hurt. Do I really want a 100% top to bottom progressive grind? What about the off-sides - blurry vs sharp? How do they compare? Is a wide Trifocal still a good option? How does that compare for cost and specs? Great advice so far! Do part 2 please!

You know I don’t wear a prog so I can’t exactly say … but I’d I do in the future the newer digital bifocals seem like the way I would go

I'm new to the glass's world. Just had my first eye exam and the doc recommended progressives. I tried them but do not like them. First reason; my eyes are not too bad, yet I can see pretty well nearly 20/20 without glasses but glasses do clear things up in the distance. I don't like that I need to move my head to get to the correct focal position for what I'm trying to see. Example reclining in a chair watching TV you end up looking out the bottom of the glasses and it makes my vision worse than what it would be without. Second, I don't like the distortion zones on the sides again same problem if I look through the distortion zone the vision is worse than without glasses. Any recommendations besides going with single vision? I like the concept of progressives and see how they are helpful but cannot get past the issues because it just makes things worse.

Progressive's are something you have to get used to. unfortunately I do not need an additional power for reading so I don't wear a multifocal, so my personal experience in wearing one is very limited. Recommendations are usually to wear it as long as you can to allow your brain to adjust. progressive's are designed to be worn always. Fitting Height could be a little high maybe you would like less reading zone and put it more towards the bottom. There are digital bifocals where it is a hard transition to the reading zone ....nearly invisible unlike traditional D seg bifocals.

Thanks for this. I still wear lined trifocals at age 56. I have problem with them but I believe they will eventually become impossible to find. Can these digital progressive lenses be customized in such as way as to provide a reasonable vertical depth for intermediate vision?

@mhopticallabs4616 Жыл бұрын

Yes a lot of digital progressives you can pick the drop …. The optician will usually pick a reasonable one depending on frame size ….if you have a preference make sure to speak up! ….also keep in mind there are digital bifocals now where there is no transition goes right into the reading in a round seg

@goodwill6767 Жыл бұрын

@@mhopticallabs4616 Thank You for your reply. If there are digital bifocals is there anything digital that also accommodates intermediate vision the way a trifocal would? And I have recently heard of those new Omnilux DAL lenses but they look to me no different than a progressive with a wider corridor.

Another interesting video!!! Do you know in what years digital lens were introduced on a large scale? And which manufactures were the leaders in digital lens? I am guessing Essilor and Shamir were leaders in digital lens design in the late 90s?

I want to say when Satisloh developed the VFT ultra generator in 2007 …. That’s when I believe they really mealies the free form.

Are these techniques equally applied to both polycarbonate and mineral lenses? Can you address the differences between the two, what's possible specifically with these technical advances in terms of visual clarity, color fidelity, weight/thickness etc. as compared to what we knew years ago? (Also, available coatings! Why can't we get an oleophobic coating on glass lenses when the smartphone makers have been doing it for years?) My reason for asking is that I've always preferred glass over plastic for the scratch resistance and clarity, but I was steered toward plastic for the coatings and weight. I assume that this has changed on the manufacturing side, but takes the retailers a while to catch up on the sales pitch. I'm looking for someone to set the record straight.

@mhopticallabs4616 Жыл бұрын

I’ll have to look into it but manufacturing plastic is easier, cheaper safer, and absolute lighter!

@robogobo Жыл бұрын

I’m told that I’m in a minority who can see a significant difference between glass and plastic, but I also suspect there are better and worse among plastic lens manufacturers, and I’ve probably not seen a good quality plastic.

@Brazil894 5 ай бұрын

Shamir talks about making glass lenses in one of the videos about the history of Shamir. They used ceramic molds and injected melted glass to form the lenses back in the day. Although glass lenses are more scratch resistant than polycarbonate, the process to make a glass lens is longer and much more expensive. In the end, the advantages of polycarbonate lenses outweigh glass lenses. Polycarbonate lenses are much lighter, and easier to customize and manufacture.

Awesome! - I'll check you out if you sell direct. (probably not!) But you could recommend an on-line glasses vendor that uses you! (If you dare.) OR GIVE THE WHOLE LIST.

How do you know if you have a digital progressive lens ....or conventional

@mhopticallabs4616 Жыл бұрын

There are three ways I can think of. One is to look at the lens from the side to see if there is a noticeable “bump” on the front. That would be conventional. However, it could be a hybrid like a w2 or camber lens. Two is take a look at the engravings on the lens, if they are on the back that’s a digital (front would be conventional). Three is to take a look at the engravings on the lens and match it to the engraving identifier (vision council has one). That will tell you the exact progressive you have!

@AndresRamirez-gx9oy Жыл бұрын

OK thank you I appreciate it both pairs of my progressives have markings on them so now I will try to identify them..is there a site I can look at to help me verify them ..thank you for your time theres just so much to learn about lenses and the material that they are made from
