Hi, my name is Jessica and I’m a member of the R&D Team here at Transitions Optical.
Hello, my name is Delwin.
I’m also a member of the R&D Team here at Transitions Optical.
Today, we’d like to take you through an experiment that’s going to demonstrate the behind-the-windshield properties of the new Transitions XTRActive lenses.
So, today in this experiment, we’d like to talk you a little bit about how Transitions XTRActive lenses behave behind the windshield of a car.
Tell me, what are the challenges of photochromic lenses activating behind windshield of a car?
The biggest challenge is that photochromic lenses activate using UV light.
Well, now, the typical automotive windshield is going to screen all this UV light and part of that is to protect the interior of the car.
So, what we’ve done here is we’ve develop a unit that mimics that windshield of a car.
We put a especial coating on that will block the UV.
But the reason why Transitions XTRActive lenses work is that our scientists have developed especial dyes that activate not only with UV,
but also a small portion of the visible range of light,
and so we get that activation inside the car whereas original Transitions lenses don’t have that special technology.
So, we place the original Transitions lens in indirect sunlight to show the moderate activation of indirect sunlight.
Now we turn in the direct sunlight to actually show the activation that you are going to expect to see when the lenses face directly into the sun
behind the windshield of a car.
And, as you can see, based on this experiment the XTRActive lens is moderately activated and the Transitions fixed lens has minimal activation.
Relative to full activation when you are not behind the windshield of the car, you’ll see the XTRActive lens has good activation.
So, really what we want everyone to learn today is that Transitions XTRActive lenses have a special technology that allow them to activate in a car,
whereas traditional Transitions lenses do not have that technology.
