Testing just how quickly the new Transitions Gen S fades to clear compared to the previous Gen 8.

This is exactly what we need! So many videos with unnecessary info. Thanks for going directly to the point! ❤

[@UseMyFrame]

You're very welcome, and thank you! :)

[@PointsNerd]

Thank you so much! This helps a lot! I just got Gen S lenses and just waiting for the order to be completed. Great to know that they fade back so fast!

[@amirulaizzatzamani6738]

That's quite fast for the new generation..can you do a comparison video comparing the gen s vs photofusion x by zeiss? Would love to see them

[@J43rv1]

this is pretty interesting, I thought the Gen S was supposed to get darker than the Gen 8. This is the only place I can find anything about VLT information, so thank you. It would be really cool to see the different colors VLT percentages, but I assume grey will be the best.

[@lukew2194]

I would love to see some videos comparing the different AR coatings from Essilor, Zeiss, and Hoya. There is almost no info like that on the internet.

[@UseMyFrame]

How would you like to see them tested?

In Spain, only the 8th generation is currently available to order.

Great comparison thank you!

Greatly appreciate this video my guy.

Please make a comparison between Gen S and Xtractive

[@6006579]

Thanks pal.

[@tsuyoshinyc2]

At the first state both lenses were 90% transparency. That's because the room lights were affecting the transparency? In other words, the transparency is slightly affected by the amount of brightness along with the amount of UV Rays?

[@magneto1978]

Thank you for putting out this video. It’s very useful. I would love to see you. Do a follow up video with the other colors though because I’ve heard that the new ones are much more true tone and less Gray.

[@ruiamaral1974]

So basically Gen S darkens equal to Gen 8, thank God I have Gen 8 Grey :)

[@arxefix]

This is the most helpful technical review so far. Thanks a lot for your effort! I would love to see the quantitive performance comparison for the Transition Xtractive NG as well. They should be lower from 6% when in darkest state right, because xtractive NG said to be the darkest on the market? Also, I am curious if the difference in coating between the xtractive NG lenses will affect the darkest state. Because i have Xtractive NG grey, one has a Sapphire and the other one is optifog. When in darkest state, the one with optifog coating is darker than the one with sapphire coating.

Please do comparison, zeiss photofusion x hoya sensity x essilor transtition

[@HairBilly]

Great video, thanks👍 what about xtractive, is it true that they're slower to turn clean? Like 2 minutes more?

[@reynaldopreciado9321]

Nice work for gen s. Can you compare transition xtravited vs gen s

[@UseMyFrame]

Will do!

[@akahina]

Nice job! Can't wait to get my new Gen S.

Let’s not forget that the temperature of the lens has a huge part to play in the performance. The warmer the lenses the worse they will work.

[@hawaiian-cerveza]

How so? I've read contradicting info that when its hot it changes slowly and the same for when its cold.

[@dommer256]

Hi! How does ZEISS photofusion X compare? Thanks

[@saeco88]

Very usefull, thanks, the gen S look darker in color

[@lukew2194]

These lenses don't have 6% light transmission when fully darkened. These lenses fit in category 3 with around 18% light transmission at the most. You have to take into account that you are starting with only around 90% light transmission.

[@UseMyFrame]

You are partly correct, these Transitions would normally darken to a category 3 but the UV light we use gets them darker than you would usually see from just wearing them outside. The 90% starting light transmission has nothing to do with them darkening so much. All lenses will block/reflect some light and rarely achieve a perfect 100% to start (even with additional coatings). This is a good observation, however, our testing machine is very accurate (+/- 1%) and these lenses really did darken that much (down to a 6% light transmission as shown in the video). To avoid this we could take the lenses outside and test them there, but that presents other variables that are even more difficult to measure (time of day, clouds, actual UV reaching the lenses, etc.). So while this test will make the lenses darker than you'd typically see, it gives us common (and repeatable) testing conditions. So while not perfect, it provides a baseline that we can use to accurately measure/compare.

@@UseMyFrame Yeah, the only problem with this is that some people will get the gen S and will be disappointed that they don't get as dark as a pair of sunglasses. Personally, I'm very happy with my gen 8 lenses but I knew going in that they will not replace sunglasses.

[@hawaiian-cerveza]

​@@lukew2194 I like sunglasses but love my gen 8 for everyday usage. I also thought that the gen s got darker than the gen 8. Maybe its just me but the gen s are said to get as dark as sun glasses but apparently not.

[@lukew2194]

@@hawaiian-cerveza They do get as dark as sunglasses just not the same level as typical sunglasses.
