Is that mean the thinnest high prescription glasses is high index lens or glass lens if anyone has it these days and small (but allowing progressive) round frame with pd dead center of each lens exactly the distance between centers of both eyes?

I have always wonder is the lens thicker on a bigger blank size lens than a smaller with same prescriptions, in same center view area. The edge is thicker in the bigger blanksize of course I understand.

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.

Thank you! This information has been so difficult to find, trying to build my own camera lenses

What powder that using? I'm curious about that

Crucibles on the ebc 900 have 12 pockets for more chemicals to be added. Didnt see Zarkonium?

Of course. Avoid entering myopia. By scientific concept and methods. Thanks for your advice.

Does a higher decentration only effect the weight and "comfortableness" of a frame on a person's head and face, or does it also affect the vision and optical clarity?

How much

Sit on your hands , you look like your parking a plane at the airport .

Perhaps you should sit on your hands !

Love the Video! But did you have to record it in the most noisy place you could find? 😅

very clear! thanks for putting out these contents

No mostraste el stand de Schneider 😢

Great Video! I have a pair of Essilor Varilux Lens with Transitions XTRActive and a Fire Red Mirror Coating. XTRActive Grey with Fire Red Mirror Coating Pros + All visible light wavelengths activate the XTRAactive vs. UV activates the Transitions Gen8 + Great for outdoor sports and driving, use them everyday for walking and running outside + Become much darker than Transitions Gen8, even more so when below 70 F outside + Better than Transitions Gen8 for outdoor activities and driving + Quick to darken and lighten, still work great after 1 year of daily use Cons - Prefer not to use indoors, too much light attenuation and too many internal reflections from indoor light sources - Try not to use these outside at night because of internal reflections from vehicle lights, street lights, etc. - Still usable after dusk, but prefer to wear Transitions Gen8 or non-Transitions lenses

Woot

Does anybody see the irony? He's talking about AR coatings while wearing uncoated glasses lmao 🤣

Thanks for the interesting video. Can you explain more about the base curve? What are the differences on the base curve selections on the Varilux X Series vs. Physio vs. Comfort? Does the Varilux X Series have a wider base curve selection vs. Physio vs Comfort?

Sometimes I got 10BI oc receipt...

I’ll be using this series on my Opthalmic Lab course. Thank you!!!!! This is great info.

Thank you so much

we wait this part about eight month, great job, thank you!)

How are you able to get that first fit and not require heating the frame? Is that the same with you Bisphera as well?

Small Eye Wire, high index, maybe aspheric. It's not that complicated. And I am an ABOM.

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.

I love this machine I use it at work but it allways has an issue … usually it always says arm over load 🫤

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.

Extremely informative. Great vid.

Thanks for the video. Would be great a video about anti-reflective testing.

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

High index +9.00 add +2.00

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!

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.

I'm on my way to have you make my glasses.....

need to learn more this

Visionexpo fantastic next year i will coming

MH Optical Labs, congratulations the best point you made for high RX/difficult perscriptions was to seak out an independent optician. There are many other consideration: starting with the percription - those thick lens are not only heavy (causing nose slide effection vertex distance), some can cause facial contact resulting in under correction (here the patient or their parent should consult the optometrist about vertex distance), also consider angled cut-back for the lens edge (on minus lenses). Yes, small frame openings - try to stick to under 52mm, ideally smaller (almost impossible to find in adults). High index lenses, as high as you can afford, and they will need anti-reflective coating. If glass can be use, choose it (they will weigh more [as an example I've had RX glasses of 78 & 56 grams], can be had in higher index, if not broken in the lens can be used as backups for a very long time - as a bonus has a better thermal conductivity resulting is shorter blinding time due to temperature fogging. Another thing to consider is eyeglass retainers. Fabric ones like Croakies (mirco suiter) can distribute glasses weight on the ears. Wire frame or "plastic". Fully enclosing frames definitely! Most would rule out wire frames, but consider: thick lenses can contribute to uncomfortable heat around the eyes; the raise nose pads of wire frames allow for some adjustment (very helpful for heavy glasses, or one that will be fitted over a good length of the nose - multi-focal point lenses are seldom desired due to life long historical habits). Given how integrated eyeglasses & RX of high diopters lenses are (with some choosing frames first: due to style, size, historic compatibility, adjustability, possibility of vertex compliance, weight consideration) - here is another tip. If you're a high RX, check the eyewear available at optometrist's affiliated opticians for glasses with small frame opening - even most that claim a myopic speciality will have nothing to offer.

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?

As always, you have explained it so well. Can you make some videos on autoblocking (assuming its alloy involved) and alloy reclaim / reuse?

India awalabul prid

You started off by saying that poly carbonate is a soft plastic???? My friend you have absolutely no idea what you’re talking about

I am from India ....can you say glass tinting metarial name ....

Laboratório do meu sonhos,sou um grande fã da satisloh, parabéns pelo conteúdo 👏👏

Love the content, thanks

Another great video!!! 1) What percentage of stock vs. surfaced lens do you process today vs. 10 years ago vs. 20 years ago? 2) When did they start surfacing progressive lens? In the 90s? 3) Where do you see the future of stock vs. surfaced lens? 4) Can you do a video on the history and development of progressive lens technology? 5) Surfaced lens, free form lens, digital lens all mean the same? Any other names for digital lens?

Part 2 sorry for the delay! kzbin.info/www/bejne/nYa3n4GHmaZ9i80

I have a pretty strong eye glass prescription of -6.00

Does the lens need to go through an auto etch machine after loading on clips/racks to get cleaned before hitting the hardcoat machine? In your video the satisloh machine does the stripping of factory hardcoat, so if stripping and hardcoat is carried out in one machine does it still need another cleaning prior?

waiting for the next épisodes, thank you so much for all explanations

Today's lenses r not good at all..digital freeform lenses u should bring old piccolo & lifestyle design
