Polarized Sun Glasses and PDAs

All,

I'm picking out a new pair of sunglasses for soaring and I had a few
questions.

Has anyone had problems seeing their PDA while flying with Polarized
lenses?

Is anyone flying with Oakley black iridium polarized lenses?

Thanks,
Michael 'BK'

Perhaps risky, financially. My scree, an older IPAQ, is almost invisible
with a polarized lens.

I used to fly with polarized lenses. What I found is that you have to
be careful that the polarizations of the screen and the lenses didn't
interfere. For the LCD devices I flew with at the time (GPS-NAV
screen, digital battery monitor), I pretty much got lucky and they
worked fine. But I noticed that with some other devices, for example
my FRS walkie-talkies, I had to hold the device sideways to read the
display.

Bottom line, I'd suggest taking the PDA with you when you try out the
sunglasses.

Thanks, Bob K.

Using an Ipaq 39xx and polarized Eagle Eyes I can see the screen fine.
Gets rid of the glare. The glasses do not have a dark tint.

What Bob said.

Also, on a more general note:

Some canopy materials have bad interactions with polarized lenses.
When I was training in a Diamond DA-20 I made the mistake of wearing
polarized lenses once and was treated to a wonderful changing moire
pattern all over the canopy, as I turned my head - ugh!

So check your canopy as well as your PDA, before you drop a lot of
dough on fancy lenses!

And last but not least, with polarized lenses reflections are suppressed.
That means that you easely miss a sun reflection in the cannopy of an other
glider.
Missing other traffic means an increased risk of collission.
No polarized glasses for me in the cokpit!!

and you are banking that the next gee whiz flash bang gismo to come
down the line is not going to have a polarized screen that interferes
with your sunglasses. I picked up a pair of prescription ray ban's a
few weeks ago and decided to make life easy and got non polarized
lenses.

It is possible that you might miss a sun reflection on a glider.
However, polarized gliders make the sky much darker, so in general they
make other gliders stand out. They also help with the visibility of
distant clouds.

You should be able to see your PDA wearing polarized sunglasses, but
you may need to rotate your head though 90 degrees to read what's on
the screen! Plain tints are probably better. Yellow to brown tints
seem best at cutting through haze and highlighting clouds.

It's not a question of the overall tint, but rather that the lens is a
strong blue attenuator, i.e. that most (but not all!) of the blue light
is filtered out. Granted every blue attenuator will have a brownish
overall colour, but not every brownish lens is a blue attenuator.

Personally I wear Zeiss Skylet lenses and couldn't be happier. Not only
do they have a well tuned colour filter, but they also are optically
perfect. However they are pretty costly, so you should only consider
them if you don't tend to sit on your glasses.
