The last feature I'm going to talk about is something called i.Scription.
When your doctor sends your prescription into the manufacturer that makes your lenses, they
use a unit to describe the refractive power necessary to correct your eyes, called a diopter.
A diopter is often written down with an accuracy of up to a fourth of a diopter.
However, with i.Scription, they make it accurate up to a 100th of a diopter, which means the
glasses can be truly and utterly custom tailored to exactly the way your eyes are, and that
provides a number of benefits.
If you're like me, you do a lot of night driving, which means you deal with something called
halos and star bursts.
To describe these things is going to be a little difficult, but I think you might have
seen them before, especially if they affect you quite heavily, like they do me.
If you've ever looked at a streetlight, as you drive down the road, and there appears
to be the light itself, and then this kind of glowing haze surrounding it - that's called
a halo.
Physically, it's not there, but it is an optical illusion of sorts that happens when you happen
to be looking at it, and for some people it takes up a larger portion of their vision
than others and it can be very detrimental because it blocks out their view, to an extent,
of what they can see, and that's not good.
The worse the halo, the less you're able to really concentrate on other things, because
what should only be taking up this much space is now taking up that much space, as far as
your vision is concerned.
Next, there's something called a star burst, and no, it's not the candy.
It also has to do with lights, and taking the same concept – looking at a streetlight,
as you're driving down, you have the streetlight, but now you have these rays of light shining
out from the source of the light, like as if you can see the photons bursting away from
the streetlamp, and it can take up a very large portion of your vision.
Not a solid piece, but little lines of this light, going everywhere.
It's another optical trick your eyes play on you, so to speak, and it's not good.
It causes a lot of people to be very wary of night driving, but when you have i.Scription,
it helps reduce these two things considerably, because now everything is focused in so perfectly
that you don't get this weird variation that causes those two things to be so predominant
when you're driving at night.
That being said, Zeiss does make lenses, specifically for driving at night.
If you're a truck driver who's making a long haul from one state to another, you might
want to consider the glasses that Zeiss provides, specifically for driving at night, which reduces
the glare caused by things like rain and the halos and the star bursts, and whatnot.
But i.Scription is something that can be done with trivex and, I believe, polycarbonate,
as well, that will enhance your ability to focus on things at night, and it also comes
into play with the color contrast just like the clarity of trivex did for me.
On top of being able to focus on the road without these optical distractions, you're
now able to distinguish little details on the road a little bit easier, as well, which
should boost your confidence in being able to drive at night, and driving at night can
be tricky.
Although there's less people on the road, there's also less light on the road, less
details to pick up and less information for your brain to be able to use to process so
that you can drive safely.
i.Scription doesn't cost too much more extra.
It's a feature you should consider if you drive at night all the time, like I do, and,
with that being said, that's pretty much all the features that are packed into these lenses,
explained as good as I can do it.
Knowledge is power, and now that you are armed with this knowledge, you can take it to your
eye doctor the next time you get your prescription updated and you have some talking points to
bring up with your doctor and say, "Hey, what about this, this or this?" and you can get
your eyewear custom tailored to the exact way that you want it for your lifestyle, because
the options exist, the technology is there, and it is so worth it to try and get these
extra features.
If you have medical insurance, it pays for a certain amount, but trust me, the little
bit higher price tag is so worth being able to see the world in such a beautiful way that
you haven't seen it before.
That being said, thanks, guys, I'm glad you watched.
