Ahh this one comes up often! Is going to a larger lens size the best way to get more from a progressive lens? Let's look a bit at the factors that play into this and see. When it comes to progressive lenses and lens design, there are a myriad of factors to consider, with prescription and uses at the forefront, but overall design length "longer" may or may not be better!

Love your videos so much my friend allways a treat to watch
Thanks Lloyd! Hope you've been staying safe and well, thanks for always watching! 😁
I really appreciate your honesty and depth of information. It is difficult to find unbiased advice. I have watched a few of your videos over the past few days trying to understand why there are so many choices in lenses. I have been purchasing 1.57 lenses for years. My prescription is -225 - 150 85 with add 2.5. If I understand you correctly, I would have better clarity if I purchased the 1.5 lenses with my mild prescription, instead of the polycarbonate?
Correct, 1.5 cr39 or 1.56 hivex would be a noticeable improvement particularly outdoors with minimal change in thickness in a well chosen frame 🙂
Why bash varilux x but not give a better alternative.
Because, unfortunately, the better alternatives are very difficult to find. The negative add methodology of the varilux x is very problematic for the specific problem I’m talking about here, but many mainstream progressives today are plagued with similar issues due to being variable corridor for ease of use and minimal staff training.
Really helpful information I learnt alot here, in particular about how hyperopes do better with smaller frames, thanks!
Glad you enjoyed the video! Thank you for the kind words and for watching 😁🥰
“Never take your glasses off with one hand” if I had a quarter for every time those words come out of my mouth I’d be a millionaire 😂
"Never take your glasses off with one hand" immediately after taking glasses off with one hand 3 times. 🤣
I despair of ever seeing well again. I didn't wear glasses until needing readers in my 50s. Next thing I knew I lacked clarity at every distance and ended in progressives. Now I'm nearsighted in one eye and far sighted in the other and my brain seems not to appreciate this. My optometrist office doesn't have anything to say about lens choices or anything that can be done to get more clarity at each range. Who do I look for to have this discussion with someone who can make my glasses work better?
Iseikonic or Shaw lenses can help to control the balance between the eyes. That’s what will benefit you the most. This design work can sometimes be wonky with progressives depending on the delta, and the best solution may be a few pairs if you spend a lot of time at various viewing zones. Good luck! 🥂
Like ur videos Sir,,,I'm a lil confused,I ordered Nikon progressive lenses,also they are transition xtractive,so who makes the lenses,Nikon or transition,I thought they both make lenses,or is transition a film that Nikon will use,,,,sooo confused,I hope I didn't confuse u,,,thanks for ur help
Technically none of the above, but that's getting incredibly convoluted about it ☠😅. In more simple terms, Nikon is purely branding in this sector, and is an essilor designed and manufactured lens for Nikon. Transitions is indeed a coating/layer bonded to the front surface of the lens from the factory before any surfacing or prescription power is added. Further to the point, a seperate lab entirely actually makes the lenses, and in many cases the lenses are cut for the frame separately from that as well.
@@ThatGlassesGuy03 I seen a review with packaging from transition with a lens inside leading me to believe it was a brand of lens,,,
@@r.c.wilson6324 gotchya, nope just a brand, they do indeed put the transitions trademarks on lens packaging using it of course.
I hate the fact that I am a hyperopia! I am a plus 5 w a +2 add. I do get the 1.74 lenses but hate hate despise the magnification AND the weight of the glasses on my nose. do u have a bag of tricks for this?
Indeed I do! First of all 1.74 is only adding weight and not making any difference at all in thickness (vs 1.67 it may actually be thicker too depending on the surfacing lab). The magnification is handled in another way entirely, and comes down more to getting frames that fit good and close to the eyes. 🙂
Thank you. I watch your videos often and they are so very helpful! You talked about golfers and progressives. Any tips when working with golfers and fitting them in progressives?
Advice, don’t. 😂. I have a few golfers that wear their customized distance priority progressive to golf in but it’s not ideal. Anyone that spends some time on the course needs something a little more creative than that.
I have Varilux X series lenses in a large frame and am presbyopic. Would this particular progressive design generally work better in a smaller frame, or does it vary from person to person for other reasons?
There's several reasons the results will vary, including the prescription itself. I'll say, there are a host of reasons I don't fit the varilux X unless someone specifically requests it AND isn't able to wear the lens I select for them instead. Hasn't happened in the 4 years I've been open 😎
@@ThatGlassesGuy03 Before X Series I had Varilux Comfort DRX with a smaller/shorter frame, but my reading zone was uncomfortably small vertically. That's why I got larger frames and decided to try the X Series. Husband has Physio DRX and likes it. Any reason Physio DRX may be preferable for some folks? I'm thinking ahead to my next pair. It's so hard to find real/useful (as opposed to promotional) information online.
@@chachiwahi don't feel bad, most opticians are working from marketing materials too. Comfort in general is a balance use design, physio is distance priority. Both of these as the DRx are backside surfaced designs (nothing special today) and use their own trickery to optimize the corridor for each RX and supplied measurements, where the comfort prioritizes all day utility and is a very SOFT design (small fields of view and lots of distortion, but not uncomfortable distortion and easy to adapt to.. thus... comfort.). Physio is a hybrid design that's harder in the distance field (distance priority.. see how this starts to work? 😎) varilux doesn't advertise the physio as a distance priority design today, because that changes how it's fit and used.... but I assure you, it is since its inception over a decade ago.
Various use and rx cases make each of these applicable in their own situations. Neither of which is anything particularly special or groundbreaking. It would take an entire book to go much deeper, but that should be significantly more than you'll get from any marketing material and a jump up from a majority of what opticians know about it.
@@ThatGlassesGuy03 Heh heh, consider writing that book!
Sweet cars :)
I’ve been thinking that those lab created diamonds would make cool lenses because the refractive index is so high
Funny you mention that! I've thought of it before as well. Unfortunately while the refractive index is very high, most other optical qualities of the material are terrible. Worse than the loathed polycarbonate of yesteryear (which was so poor you could see the carbon in the lens 🤢) 🤣
@@ThatGlassesGuy03 I think the surface would have to be coated too, so that others would not be blinded by the reflection. Just a thought. I wish I could post a picture of my glasses, I had them made custom for me, they're super cool
Is there a brand of lenses that you like best? I see you don't care for Varilux.
No. Because I don’t get caught up in the marketing bs and name games. I use the lenses that work the best for my clients. I see these questions in professional groups and give the same answer. There is no best lens. No best lens brand. There is an optimal lens for each person, prescription, and use. Nothing more, nothing less.
@@ThatGlassesGuy03 thanks for the reply. I wish I could come to get my glasses fit with you!
Seems like you don't give out info that could help those that don't live in your area to come into your practice . You say varilux isn't that great but so many others say they are.
It’s designed for ease of use and targeted at the masses. Hard to say it’s just bad, but it creates issues that can’t be rectified with another varilux lens. I absolutely market as such and am known for my lens expertise locally. If I had a multi billion dollar marketing budget I could have the entire world say my lenses are the best too. Same as knowing ray ban isn’t the best. 🤷♂️
@@ThatGlassesGuy03 if you're not going to say exactly why varilux is crap,I really can't take you serious. I've spoken with about 100 people that went from other brands to the varilux X and ALL said they were much better . These are real local people from my area. In a real conversation where they actually explain why.
