Amongst the Soaring Communitity does anyone have experience with Sun
Tiger sunglasses. I saw the ad in Soaring and wanted to cut through
the ad-hype. I would appreciate comments concerning the quality of
them filling prescriptions.

Thanks in Advance.

I've been using Rx Suntigers for about 3 years now. It took me a few days to
get used to them since everything seems brighter, yet no glare. I still prefer
my Serengeti's for the beach, but I prefer the ST for flying.

My only complaint is they seem a little scratch sensitive, even with the quartz
coating.

Get them, they're great.

I've been using them for over 10 years (yellow non-polarized). I sent
in my prescription lenses for treatment and fitted them to my own
frames.

You need to be aware of color perception. Blue appears black, yellow
appears white, and new green vegetation takes on a remarkable
brilliance. This may cause problems with crop recognition until you
get used to what a crop looks like.

I heard that the BGA discouraged their use for that reason but never
saw that info first hand.

I got a pair and they performed as advertised except that my
color vision was impaired for as much as half an hour after
I took them off. I am a bit red/green deficient (per my
wife) but my color perception is good enough for a 3rd
class waiver.

Nonetheless, I disliked the effect so much that I no longer
use them.

Mine are non-prescription...but they are great.

They do what is claimed: cut down glare and improve detail. Once you get
used to the color shift (they block out the blue spectrum) you will see an
increase in shadow contrast and detail...even in haze. I now pick out ground
reference points easily and see other A/C better at a distance.

The issue of scratching is true as well as be careful with conventional
glasses cleaners. I had a little amount of the coating come off when using a
liquid lens cleaner.

The only problem I've had is after a few years the sweat gets between the
layers and starts clouding the lens. Apart from that I think they are
excellent for soaring. They certainly highlight the small whisps of clouds
that are difficult to see without them.

I wear contacts so I did not need prescription. I've had mine for 4
years and will not fly without them. It's not hype. You really do
see better in all conditions. You will be surprised at how your haze
and relatively low light vision improves (pupils are more open?).

If you order, tell them you are a glider pilot. I believe they have a special tint.

I've flown with them for years (sadly my current pair are bifocal).
Absolutely true that its easier to see haze domes, wisps, etc.
Highly recommended.
Best Regards, Dave

David,

I also bought the Sun Tiger's though in my case it was just at the
beginning of the season this year. I had the progressive lenses made
and have found that the quality of the perscription was every bit as
good as both my clear and shaded sunglass perscriptions have been. As
others have said, the color shift takes a bit of getting used to but I
found that I made the change pretty easily. Picking out clouds, other
traffic and even thermals with slight amounts of dust that I could not
otherwise see, has become a breeze. I have also found that after a
full day of flying I don't have that slight headache caused by the
squinting that I always did even with a pretty dark sunglass. Lastly,
I like that fact that the glasses are not polorized. I don't get the
spots on my canopy that I used to see and since I was one of the folks
that bought a Cambridge 302 with the polorized glass that was 90
degrees out from normal, now I can actually see the instrument face
without performing contortions in the cockpit. Go for it - it's not
hype.

Sooo, Bob, now you can tell Alice that you thought you were at K-Mart
next time you're caught in the red light district. ; )

Come to think of it, I gotta get me a pair, too!

Wow! Lots of interest in this topic!

One of our members who has made a close study of optics, recommends a
very lightly colored polaroid for gliding. Particularly interesting
points being:

* a dark colour simply causes the eye to open wider to let in an
appropriate 'amount' of light. When opened wide the eye is very
susceptible to stray light coming from the side of the lenses, and the
depth-of-field is dramatically reduced. Keeping the eye small ensures
that maps, instruments and long distance focussing are likely to be
much easier.

* be certain that the lense stops UV (some offer little resistance!).
The lenses should be large in size to maximise the UV blocking.

* Sure, polaroid may have a problem under some canopies . . but this
will be well known for that particular craft.

Question for those advocates of the SunTigers (unlikely to be
available here): Have you compared them to polaroids with similar
colour?

(perhaps SunTigers are available as polaroid too?)

Cheers,

Anyone able to comment on Polaroid vs SunTigers?

Thanks for your comments Henryk and Todd,

Looks like we three agree on not using *dark* sunglasses!

Cheers,

Jim Kelly

| Jim,
|
| there is a big misconception in what you wrote. For polaroids to be
| polarizing they have to absorb 50% of light, and then there are more
| efficiency losses. Sun Tigers are about 50% or more transparent
| (integrated intensity) so are likely to be "brighter" than
polaroids.
|
| In addition to spherical aberrations that you refer to talking about
| depth of focus there is also chromatic one. Suntigers shrink the
| optical bandwidth effectively reducing chromatic aberration.
|
| Using Polaroid glasses and liguid crystal displays is another trick
to
| be mastered as the latter also rely on polarized light.
