- Hello, I would like to welcome you
to the Laramy-K OpticianWorks training center,
where chances are if you're at work
and watching this, you'll look like this.
And everywhere I look on social media,
it's people talking about wearing these,
and wearing these and having trouble
with their glasses fogging up.
That reminded of a technique
that they use on sports goggles, rec specs.
Remember there was an entire line of cycling glasses back in
the 90s that had these series of holes and cutouts
that were supposed to help reduce that fogging issue.
I thought hey, let's give that a try.
So, let's hit the bench and play a little bit,
drill some holes, put some notches do some work on
the edger and see if it helps.
Let's start with hand.
We've done this before, you can use
a pin drill, you can, you know, finish things up
with a file, you could use a Dremel and a small bit.
And unless you're wearing the glasses, drilling
a hole through the lens ain't gonna hurt anything.
To experiment or play, I grabbed a trilogy
or a trivex lens.
Little minus 50, no bells, no whistles, no coatings.
(slow upbeat music)
This is the Santinelli LEXCE trend
and, unlike at the bench, we're doing things by hand
and basically, only your imagination is a control of
what you can do.
Here, it's imagination, the design software
and of course the capabilities of the machine.
(electronic beat)
I have got five lenses keeping in mind
that these are uncoded.
A great AR is greatly going
to reduce fogging on a lens.
I have got that one with the notch and the notch cut out.
I've got the notch in the holes, I've got random notching.
I've got random holes along the outside edge
and I've got my favorite, the one with the holes
that are angled along the bottom where perhaps
that breath would first hit the lenses.
I have got a control lens in my right hand side here.
Has no holes on it, no changes to it whatsoever.
That'd be our one that we're comparing these other ones to.
So, it's really humid out here this morning.
I'm gonna crank the AC try to get it cold in here.
Gonna put on my mask.
I'm gonna bring that camera way, way in tight
so you can see if any of these make a difference.
All right, let's give these a try.
(heavy breathing)
And those are just horrible.
Right.
(heavy breathing)
I Wanna think that this one's clearing
over faster on this side
but I can't really say that for sure.
Maybe you can tell, I certainly can't.
It's certainly not causing a great deal of difference.
(heavy breathing)
If I close my eye and Look up into the upper nasal
it is actually clear around those holes.
What exactly that tells us I'm not sure but...
(heavy breathing)
This is what I really expected to have.
Some results expect the breath to come up kind
of hit either turbulence or pass through
the lens, behind it, in front of it.
But clearly, that is not the case.
(heavy breathing)
And again, if any one of these was gonna work,
I certainly assumed it would be this one.
I almost wanna say this is actually making things worse.
To be honest with you, I don't see.
Nothing that we did there was truly dramatic enough
to say that spending your time drilling holes
and venting lenses is really worth a darn.
Now of course failure is always an option here
at the Laramy-K OpticianWorks training center,
but it didn't make the results any less disappointing.
I really wanted this to work.
What I showed you, the hand drilling
and the Dremel tool and the edger, there was
a very time consuming set of projects.
Ended up on the phone with Santinelli.
I also asked a couple other people to try it,
just experiment a little bit, play they did.
They ended up with very, very similar results.
One person did feel that the lenses cleared faster
when they were vented.
Would it be worth all that time and effort?
Mmh, probably not.
Next week we will take a look at some of
the anti fog products that are out there, the claws
and the sprays.
Until then make sure every lens
that you are not putting holes in, comes from Laramy-K.
