Backpacking Background:
For the last 15 years, backpacking has become a passion. I am a four season backpacker and an off-trail navigator. Although I do take yearly trips to the American West or Southwest, the majority of my trips are in Michigan and Canada. My pack weight varies considerably, but my base weight is under 20 lbs (9.1 kg). I am primarily a tarp camper, that averages over 50 nights a year backpacking in a huge variety of weather conditions, including relentless rain, wet snow and sub zero temps.

RC36:  a Rose Copper universal lens providing the best vision for the widest variety of light conditions
 
Yellow (and Yellow Max): for low light and flat conditions
 
Polar Gray: a polarized lens that reduces 99% of reflected glare from water, sand and pavement
 
Sienna (and Sienna Max): for sunny or slightly overcast days
 

 
Long Term Testing Data
 
Field Location/Conditions:
 
During the long term testing period of four months, I have backpacked a total of twenty-three nights ( five trips).  Most of the trips were in the two to five day category with the longest trip being eleven days.  My first two back country trips during this period were taken in the Lower Peninsula of Michigan. Conditions consisted of highly deciduous forest with some open pine forest and river walking. Late spring to summer-like weather varied from semi-cloudy to sunny with temperatures from 40F (4C) to 85F (29C).
 
Two of the trips were located in the Upper Peninsula of Michigan - again mostly deciduous forest, river canyons, open shoreline, and lots of bushwhacking through dense cover. It's been an unusually hot summer in this part of Michigan with the temperatures ranging from lows of 40F (4C) to highs of over 90F (32C). Semi-humid conditions have prevailed with less humid evenings.
 
My longest trip was taken to the north shore of Lake Superior in Ontario, Canada. Conditions consisted of dense boreal forest, open rock outcroppings, river canyons, and open sandy beaches. Temperatures during this eleven day trip were moderate. The highs were from 80F (27C) to lows of 50F (10C). There were only small intervals of rain, with sunny partly cloudy skies prevailing.
 
Although all of these trips were at low altitude ranging from 600 ft (183m) to 2000 ft (610m), there was significant elevation changes - lots of climbing and descending. The Smith Theory lenses have not only been my constant companion on these back country trips, but they have also been worn on an almost daily basis for other activities. These activities include road and trail running, bicycling, day hiking and driving.
 
 

 
 
Summary
 
 
Testing Thoughts:
 

Through the process of extensive testing of the Smith Theory lenses, I have come to the conclusion that they are an outstanding product.

I have addressed every initial concern that might occur with these glasses and I have found none to be significant (see cons below). They are highly comfortable. The lenses have been easy to change once I figured out how to do it efficiently and they have been highly indestructible even when stored in the soft-shell case that was provided. I have put them through the constant grind of bushwhacking and they are still scratch-less and stay put through the extent of my activities.

After utilizing all of the lenses,  I have developed my preferences for favorites. Overall, the Platinum Mirror lens has been at the top of my list. It is the most versatile to me for a variety of activities including driving. The silver mirror finish reflects glare away from the eye especially important in long distance vision.

I also love the RC36 lens when I am traveling deep in the forest. It makes everything doable. I can readily see all the rocks and brush that I might clumsily miss with darker lenses on my face. The depth perception experienced was especially keen when the light faded in the evening.

I thought I would be more enamored with the Polarized lenses while walking along or canyoneering in the water, but it may be due to the fact that most of my back country days were spent in semi-cloudy conditions and not in full sun.

Two of the lenses that I tested were the Max version--that is, they had longer lenses for more eye protection. One of those options was in the Yellow Max version and the other was in the Sienna Brown Max version. I found the later to be useful, but the former to have little use for me. It had to be raining with dark gray skies for me to use the Yellow version, as soon as the sky lightened up even a shade over dark gray, they were too bright for my sensitive light blue eyes. Ideally I like the concept of the longer lenses, as I do a lot of extreme bushwhacking so my "perfect" lens would have been a RC36 Max lens for this purpose. I checked the Smith Optics website and found that the Max lenses could be ordered in 16 different versions including the RC36 Max.

I will continue to use all of these lenses over the long haul. It will be interesting to see if these lenses perform equally as well in the deep cold of winter. As indicated in my field report for this product, I was able to utilize them for late winter snow activities but most of the overall testing in the last six months was done at above freezing temperatures.

Pros:
  • Highly indestructible
  • Versatile
  • Curb appeal
  • Great fit for a small face
  • Comfortable nose and ear pieces
  • Complete eye coverage
  • No slippage when sweaty
  • Easy to clean
  • Changeable lenses stayed in place during exertion
  • Impact resistant
  • No signs of wear after extended use
  • Complete glare coverage around eye area
Cons:
  • Long learning process to efficiently change lenses
  • Soft shell case (it always made me a little nervous)
 

 
Tester Remarks 
 
This is my first pair of Smith Optics glasses and it won't be the last. I look forward to investigating other options that they market. I am highly pleased with their outstanding function and performance capabilities. Thanks to Smith Optics and BGT for this great opportunity to test such an outstanding product.
