sunglasses

My last glider had a blue canopy. I always flew with two pairs of
glasses, a pair of Serengetti's for most flying and a pair of Sun
Tigers for the days with lots of overcast or haze. I like the way Sun
Tigers cut through haze and give definition to the bottom of dark
clouds. The other option would be to get a pair of Serengetti's with
photochromic adjustment. These should lighten in the darker condtions.

I use photosensitive prescription glasses but not for glider flying.
Both the glass and plastic versions get very dark when cold but are
useless when they are hot. I have flown with sun tigers for over 15
years. My only caution is that you must be aware of the effects of
color shift particularly when assessing crop prior to outlanding.

I prefer Raybans. Get the B-15 gradient brown lenses with mirror
tinting. You get the benefits of enhanced contrast, decreased glare
from the mirror tint, and are able to easily see your instrument panel
because of the top-down color density gradient. Be aware that the
majority of Raybans come with color neutral (slightly green) G-15
lenses from the factory and that you need to specify B-15.

According to Rayban:B-15 Brown Lens - contrast enhancing lens that
sharpens details by blocking glare and a larger percentage of blue
light. Ideal for low light conditions. Excellent for enhanced vision
while driving and other fast-action activities.

Hi,
I have been flying with Serengetti sunglasses for many years in a
sailplane with a clear
canopy. I bought a LS6 with a light blue tinted canopy which make my
cockpit to dark
when in the shade of cloud. Suggestion are welcome to solve this
problem.
Regards,

OK, I wasn't sure. I have been surprised at how well I can see with my
ST's in overcast conditions. Better with than without. According to
the maker, "By removing the blue light the eye can more sharply focus
on the remaining wavelengths of light.".

Atmospheric haze scatters mainly blue light. By eliminating shorter
wavelengths you effectively remove/reduce haze and improve visibility.

The above observation is based on my experience with filters in B&W
photography, but I guess the laws of physics are the same for lenses
and canopies ;-)

I flew with contact lenses and Serengetti sunglasses for years -- until
I could no longer read the sectional charts without some serious
squinting. Finally caved in, through away the contact lenses, and
spent a lot of money on progressive-lens sunglasses. Initially talked
to the Sun-Tiger guy and was told he would not recommend his product at
the time because of a manufacturing defect in the product he received.
He suggested "Melanin" sunglasses. Purchased these through my Eyecare
Proffessional and have driven with them a "LOT" and flown with them
about a dozen times. Just love them. Yes, they are polarized, but
have not had a problem to date (don't want to start a thread on
polarized lenses!!). Just something other that Serengetti or RayBan or
whatever to look in to.

There are some very good reasons not to use progressive bifocals for
flying. Use lined bifocals instead. This will optimize the visual
acuity for what we need. distance vision (to spot other aircraft, birds,
etc.) and arms length vision (charts, instruments, etc.).

Progressive lenses are not "progressive bifocals". I've been wearing and flying with progressive lenses for years. Vision is corrected to 20-12. Progressives do take some getting used to, however they allow distance vision, close-up reading and everything in between - like the panel.

Some people cannot adapt to progressives, too bad, they sure are great if you can!

Hi all,
Thank you for your comment. I will talk with my optician about
Suntiger, Rayban and Melanin.
Will see what he recommend.

Hi again ,
I forgot one question. No one mention flying with a tinted coanopy and
the recommended glasses.
Any comment.

at all about this subject.
