Interesting site (pun intended).
When the subject was discussed some time ago on this list, nobody expressed opposition to polarised lenses in such strong terms as the referenced article. I guess that's because glider canopies are NOT polarised, but I infer from the article that some aircraft windscreens are. If that's the case, then the opposition to polarised lenses is understandable. I've now had my Zeiss Skypols for a few months, and have flown hundreds of km with them. Frankly, I think they are sensational. I've always been a fan of polarised lenses in the outdoors, and never had a problem with them in a glider EXCEPT for when the Cambridge glide computer was first fitted to the SCGC DG-1000. For some reason, the LCD display had non-standard polarisation on its own lens, rendering it black to me. Others had the same problem, and the instrument was quickly fixed. The real revelation with the Skypols is the contrast enhancement when looking at things in the sky (clouds, other aircraft). I can now clearly see wisps and haze domes that were barely visible (if not invisible) before. Likewise, aircraft stand out significantly better against the sky. I haven't noticed the Skypols to be any better when looking down onto objects with the ground as background - but certainly no worse than my old polarised grey glasses. Richard.
