How can I check if/ how much blue light my glasses filter? Can I hand my glasses to someone who can measure this? I was recommended Zeiss Duravision Platinum lenses. I asked the optician if it wouldn't be necessary to choose the Duravision Blue Protect if I want it specifically to protect my eyes from the blue light of backlit screens and was given the answer that Zeiss offers two options for equipping the lenses with a blue filter. One option is to coat the glass with a Blue Protect. However, this coating has a rather strong blue residual reflex. The second option they said is to integrate the blue filter into the base glass (Blue Guard). This option was recommended to me and I was told, since the filter is included in the base material, the glass can be coated with a Dura Vision Platinum and looks aesthetically better. It is a completely crystal clear glass with a Zeiss logo on it - how can I know any of this works? The Platinum is a very expensive lens, so I want to make sure it really protects my eyes as much as possible, as I have 8-12 hours of screen time a day since years and I already developed circadian disruption and I also have a positive family history of blindness due to macular degeneration. Would be grateful for advice!
The Zeiss Blue Guard is the most protection and the clearest of all the Blue Light protection lenses available. For now it only comes with Duravision Platinum. I only charge $99 for the Platinum coating, I cannot speak for what you were charged. There is still the Zeiss Duravision Blue Protect anti glare treatment but that has a purplish reflex that some men didn't like so they sat down and designed a clearer lenses.
@@freeprescriptionlenses Thank you for your reply. I paid 220€ for the BlueGuard base material+Platinum coating (per lens), which is staggering, but in the country where I live employers will share in the costs of glasses specifically made for monitor-based workplaces and depending on your health insurer they also cover some costs. What I was mainly looking for was a way to verify there is a blue fiilter in the glasses, but I found one. It is called a blue light testing card, you can find videos about it on yt, very cheap and easy for DIY testing if the glasses do what they are meant to do, defo recommend!
Does Crizal Prevencia have the Crizal logo etched on the lenses like other Crizal coating? I like the sound of Crizal Prevencia, a friend of mine has that, but when he fogs up his pens to clean it, I don't see the Crizal logo on the lens.
I have only seen the Crizal fog mark once in my life. It was a Chinese exchange student. I have never seen t on a lens made in North America. It may only be done in certain countries in Asia and not Europe or North America. I cannot vouch for South America, Africa or Australia. I do provide the original lens packets fr single vision lenses so I can verify that you're getting the original verified product.
I was worried about the brownish hue to the BluTech Classic lenses, but at the end of the day they do have the best reduction at 455nm! The others taper off too much by that point
Hello sir,i was wondering why did my zeiss blue light blocking lenses from blue got to a strong purple?, as far as i know i did indeed use baby shampoo and neutral ph citrus detergent to clean the lens maybe thats why ... but not completly sure
I have never heard of this happening before. Hopefully your lenses are still under warranty and you can get them replaced at no charge. Also just use a mild dish detergent like Dawn and cool to slightly warm water to clean your lenses.
Its clearer with less residual reflection than Crizal Avance. I also believe it to have a better scratch coating than Crizal as well. Just out of curiosity, what country do you live in? I love to travel.
Zeiss BlueProtect is an anti-glare / blue light blocking coating. Zeiss BlueGuard is a blue blocking treatment that is in the substrate of the lens itself as opposed to being a coating. It is also more effective and the newest form of blue blocking from Zeiss.
Hello, great video! I would be very greatfull if you could give me your advice. I don't need glasses to read, but I do need a very good protection against blue light, and a good antirreflex because I have some retinal problems and I work many all day with a computer and others screens. In my work place there is a window at my side. Looking forward to your answer.
Let me start by saying that Crizal Sapphire offers no blue light protection as compared to Crizal Prevencia. Having said that, Prevencia has a purplish hue in certain lighting at certain angles that some men dont like. It also has a yellowish brown hue all the time. But it was the first all around blue light protection that I was aware of. Now that we carry Zeiss, their Duravision Blue Protect is a much, mush clearer lens than Prevencia and costs $20 less on our website. It too has a purplish reflex at certain angles. Again much less than Prevencia. Now having said all of that, Zeiss now has a Blue Guard protection paired with their Duravision Platinum which has the lest amount of reflex and what little it has is a masculine blue. As of July 2022, its the way to go for the most protection and best cosmetic appearance. Hope this helps.
I'm not 100% sure of what you are referring to but I'd guess the first is a stock lens, meaning that its made in advance and can be used for anyone with that prescription. The 2nd one is custom made upon request. Usually when someones prescription is out of range of a stock lens.
Thank you for informative video ! I'm looking to buy bluelight glasses, please can you suggest me which of these brands to choose that available in my country: Crizal Prevencia or Kodak BluProtect or Hoya Blue Control
I would have to say Crizal Prevencia because I have not yet worked with any Kodak or Hoya lenses. But if you could get Zeiss I'd recommend them because they are so clear for a blue blocking lens.
Hey you! Thanks for watching. Im trying to introduce some new topics and info. You doing anything special for Thanksgiving and Christmas or playing it safe?
Hi,I would like to know in your opinion which is the better lens between Zeiss smartlife lens with Blueguard and the eyezen lens with crizal prevencia for high use on phones and pc .
I have ARMD & would like to have glasses with maximum blu protection, different brand here in India say different percentage of blu blocking. Please advise how much maximum protection can be available and which brand is best suited. Dr. Rojha, 73 yrs.
The most blue light protection you can get is combining two features. The first is the darkest photochromic gray lens you can purchase in India. Here in the U.S. the most common brands are the Zeiss Photofusion Extra gray and Transitons XTRAactive gray. Then apply either brands blue light anti glare for Zeiss its Duravision Blue Protect, and Essilor's is called Crizal Prevencia. Most all personal electronic devices not have blue light apps but the number one source of blue light on the planet is the sun. Ask your ophthalmologist how much time is OK to spend outside on a daily basis due to your age related macula degeneration ? And wear sun protection eyewear when you are outside. Think of it as sun screen for your eyes.
Yes, if Zeiss does not make it.such as the Transitions XTRactive polarized gray. They will buy it from Essilor and then add any of their Duravision anti glare treatments. Also Zeiss will sell me an Essilor product for $50 less than Essilor will, crazy.
@Free Prescription Lenses but you think its better zeiss dura vision platinum with blue guard or crizal prevencia. Because I have prevencia and some times I see the purple colors. That annoying
Hey, nice information dude! So, I have a lot of floaters in my eyes, and have been diagnosed with PVD. As I cannot fathom to look in the bright sunlight, I got a pair of photofusion lenses from Zeiss. I also own a pair of Duravision Blueprotect. I can see a lot of difference in the clarity of these lenses. Now that I'm like mostly adjusted to having floaters, I was wondering if I needed the photofusion anymore. Like I don't want to sacrifice clarity over the dark lenses. As I have a screen time of 8-10 hours a day, what would you recommend? Also, is the photofusion the same as the blueprotect in like protecting from the Blue light? And, what is the difference between Blueprotect and Platinum? Appreciate the work you do man!
Zeiss has come a long way and is at the forefront when it comes to optics. Good that you have adjusted to the floaters. All Zeiss lenses that are either PhotoFusion X or the PhotoFusion Extra grey come with Zeiss BlueGuard which is a better form of blue blocking technology as opposed to a BlueProtect coating. Duravision Platinum and BlueProtect are coatings. The Platinum is the best with a blue reflex and the BlueProtect is good and has a purple reflex.
@@freeprescriptionlenses damn thank you for such a quick reply! But why would the photofusion extra gray look dull to me than the Blueprotect? Is it just an illusion I have? Also, it sounds like photochromic lenses are better suited to me, as you’ve said they pretty much work the same as blueprotect. Should I try the new transitions from crizal or just make a pair of photofusions? And man, the photofusions pick dust and scratches so easily than the Blueprotects, haha
Essilor makes Transitions - Zeiss makes PhotoFusion. PhotoFusion X or Extra Grey is a Variable tint. BlueProtect is a coating. Two different things. The new PhotoFusion lenses have Zeiss BlueGuard which blocks more blue light than the BlueProtect coating from Zeiss or the Essilor Crizal Prevencia coating. Hope that clears things up for you :-)
@@freeprescriptionlenses Ah I see. So if I understand it correctly, Duravision is the lens, and the Platinum stands for Blue Guard, and the Blue Protect for the coating (referring to Duravision Plat and Blue Protect). Thanks man, appreciate it.
The Crizal Blue UV capture is similar to the Zeiss BlueGuard lenses. However, we do not think the Crizal Blue UV Capture is availble in the USA at this time.
Sir, I have a problem working with computer. My eyes can’t resist more than 10 min looking. I tried crizal essilor but no improvement. What would you recommend ? Another question, i used crizal prevencia and I added a transition coat also ! Could it be the problem of not protecting from blue light ? Thank you in advance 🙏🏻
@@freeprescriptionlenses some people say Zeiss block 50 percentage blue light while crizal 100 percentage do u have any idea on this or it's just costly and quality wise Zeiss better?
@@freeprescriptionlenses in that case I think Zeiss is better only issue I can see in Zeiss that all lights getting reflected from lens seems to appear on lens
Not compared to Zeiss Blue Protect. But having said that, Within the past month Zeiss introduced a new lens called Blue Guard. It has even more blue light protection than the Blue Protect anti glare and you can get t with the premium Duravision Platinum anti glare coating. The Platinum has a more masculine blue reflex to the lens than the purplish hue of Blue Protect. And the best part is that it is the same price now, meaning that the Blue Guard with Duravision Platinum costs the same as Blue Protect.

Your 2nd and third pairs of Zeiss will be shipped soon!
Please, do a video about the blue light in these lents, how much each one protects you from blue light.

That is good to hear! Glad you are happy with your Zeiss lenses.

Eventually I'll have to get a real job too, maybe he will hire me?
i just bought Zeiss blue protect and after i watch this video i am happy whit my new glass.
Its a great product, the clearest of all the blue light protection lenses.
can you get the zeiss blue protect in lenses that transition to sunglasses outside ?

What would you recommend better: Zeiss Duravision Silver or Crizal Avancé?
I would recommend Duravision over Crizal Avance. But having said that, the premium Duravision Platinum is the same price as Crizal Avance.
@@freeprescriptionlenses thank you, would you mind telling me why preferring Duravision? The silver is the only one I can get here in my country.
