Had good intentions of backpacking this weekend, but its just too
freakin' hot here in Tucson. Good time to stay in A/C and catch up on
test reports. The IR for the glasses is here:

My backpacking experience is a combination of Minnesota where I have
lived most of my adult life, and Arizona where I moved to take a new
job about four years ago. I have always been a "comfort-weight"
backpacker, never counting grams, but still keeping my pack as light
as easily attained. I wear sunglasses almost 365 days/year to protect
my eyes from the Arizona sun.

The features listed by the manufacturer include:
Channel break frame design for easy lenses changing - I was not able
to find out what the "channel break frame design" was from their
Two sets of lenses
Vented lenses, visible in the photo above
The Dedisse sunglasses are a member of Optic Nerve's Deuce series,
which come with two sets of interchangeable lenses. This series
excludes the following features available elsewhere in their product
line: polarized lenses, hydrophobic coating, anti-reflective coating,
adjustable wire-core temples, optical rimlock, adjustable alloy bridge
rest, and nickel silver alloy frames.
As can be seen in the photos, the nose rests are just pads integrated
into the frame. On the positive side, I've had nose bridges break on
me in the past, so these should be very reliable. On the negative
side, they hug my face quite closely and may not vent real well around
the edges causing condensation. I'll be curious to see how well the
venting mitigates this issue.
Above-left photo: a "selfie" of me with the glasses. Never had white
sunglasses before, so it'll be interesting to see what kind of
comments I get about my fashion sense.

The sunglasses seem of good quality - the frames look reasonably sturdy.
I did however notice some unevenness of color in several areas of the
frames. I tried to photograph them, and the image at left is my best
attempt to capture the issue. There seems to be some spots where the
white coating did not completely cover the grey frame base material.
The photo at left was at the base of the frame around one of the
lenses, the other spot was on one of the temple tips.
This is strictly a cosmetic issue, and would not be seen by an
observer while I was wearing the sunglasses.
Trying Them Out
I put them on and drove to the grocery store. The smoke lenses are
quite dark, and appear quite optically flat. The glasses cover my
eyes well - I noticed no distractions from brightness around the
edges. The glasses seem quite comfortable on my head, but are just at
the edge of being too small as I have a very large noggin.
I tried changing out the lenses, but they were not trivial to pop out.
I looked for hints on their website for hints on how to change lenses
without breaking them, but couldn't find anything.
I am looking forward to get the Dedisse sunglasses into the field and
seeing how they perform.
Things I Like So Far:
Good quality design and workmanship including optically flat lenses.
Appear to be very comfortable.
Good eye protection.
Things That Concern Me Upfront:
A touch on the small side. It'll be interesting to see if I get any
sore spots or headaches from them.
Thanks to BackpackGearTest.org and Optic Nerve for the opportunity to
