Experience with Sun Tiger sunglasses
David Sieber
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 had my RX Suntigers made approx 4 years ago and have I love them for
flying. It's easier to make out developing clouds and see traffic with them
than other sunglasses that I've tried. The prescription was done well and
the frame quality is in line with the price.

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.

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.

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.

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.

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?).

Absolutely true that its easier to see haze domes, wisps, etc.
Highly recommended.

the 1980's. I just moved and my index to "Soaring" articles is buried in a
box somewhere in the hangar. (SSA needs a CD that lists all "Soaring"
articles by author and subject like EAA has for "Sport Aviation" magazine).
Apparently birds like hawks and eagles don't see blue - high frequency light
that slightly blurs your vision as you eye tries to continuously focus on
"blue".
With my Suntigers, I see wisps, birds, dust, other gliders sooner than most
others - then again - I look outside the cockpit to study the sky more than
other pilots, see the wisp and be streaking to it before they notice!

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!

They will tint your lenses (tri-focals included) if
they are made from C-39 plastic (the usual plastic
lens) and if they are not already hardened.
The FAA or the Air Force did a study (on the web somewhere)
and they discounted the notion that orange lenses are
better than the standard G-15 lenses. They objected
to the greater reduction of light and to the color
shift. However, they were not at all concerned with
discerning the character of cloud wisps, etc. that
we are. I still swear by them.

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?)

for any other kind. They are bright and protect eyes from UV. They do
wonders for my night driving in busy traffic as well.
On top of the quality of the glasses themselves I am also pretty
impressed with the management team. OK, maybe they changed in recent
years (I have no indication of it), but I really appreciated the way
they handled their problems a few years ago and protected their
customers.
Originally I got their "standard" prescription glasses. I just sent in
the prescription. Now I "graduated" to bifocals. In order to avoid
problems in long distanc purchase, I got another frame, identical to
the one I wear usually, put my glasses on a xerox machine (pressed the
button :) ), and sent the prescription, frame and picture to show
where the cut should be. Worked great.
The major problem people see with these glasses is "color imbalance"
(of course this is why they are so good. Personally I do not have any
problems with that. My brain seems to correct for colors it knows, and
others... who cares.
Hope this helps.

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.

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

Here is the url to which I referred a few posts back. Despite the
recommendations here, I prefer Suntigers because they make cloud study
easier.
