chetnlisawrote a review of Julbo Stunt Zebra Sunglasses on September 4, 2016
Forgive me for offering negative criticism at the expense of hurting a brand. However, this is aimed at revealing a serious flaw with these lenses. I purchased both the "Stunt" and the Wave with Zebra lenses. I found that they impossible to clean the interior surface of the lenses. What remains after several attempts to dry the inside lenses is a blurry surface marred by the tiny fibers of whatever was used to dry them. I will gladly remove or correct this commentary if I failed to perform some unique method to clean these specific lenses. However, I'm truly baffled at this point. I actually read the directions on cleaning/maintenance from Julbo in case I was missing something. What I am ending up with is a lens surface that appear as if it has been wiped/scoured with very fine steel wool. When I run my finger over the surface of the outer lens, it glides smoothly while there is significant friction on surface of the inner lens. It actually feels "tacky" which causes any minute fibers (irrespective of several types of lint-free lens towels I used) to adhere to the surface. I'm perplexed by this. The bottom line is that these lenses are treated with something that leaves a residual sticky film or else I got two defective pairs in a row. I addressed this with Julbo directly, no fault of Back Country, to determine what may be the cause. For the record, I started with the tradition fog by breath, then used only water and without success finally tried a lens-specific cleaning solution. Regardless of the "wetting agent", the drying was impossible-using several lens wipes-specifically the one provided by Julbo which is actually the bag the lenses are packed in. Everything else (i.e. micro fiber, non-scratch lens wipes, Serengeti's lens cloth is my go to which works on all my lenses, etc.) I tried wasn't effective. The common denominator is simple, the lenses contain an adhesive coating of some type. I was tempted to use a more aggressive cleaner like Windex or ammonia but I figured I'd void the warranty. If anyone has a solution, please advise.
