With the flying season almost here I promised myself a pair of really good sun glasses. I've tried some of the polarized types ,but seem to get distortion. Any recommendations for sunglasses? Thanks,PhillySkip
I switch between Serengeti Drivers and ancient Ray-Ban Ambermatics. The Serengeti are for extreme conditions. I usually use the Ambermatics. They are also surprisingly good for night/twilight driving, because they turn bright yellow in the dark.
The issue most people have is trying to use too-dark glasses. Too dark, and you can't see the ground, it's just a mass of black ground clutter. I think you definitely want brown-colored lenses, not gray/neutral. You might expect that you could open up the shadows using blue lenses like with cameras (since shadows are mostly illuminated with blue light from the sky) but that hasn't ever worked for me, even experiments with Wratten monochromatic blue. Green is interesting and would work except you can't get any quality lenses in green. Green with about a 2-stop neutral density filter was about the best thing I tried, but you basically cannot get those already made. Even *I* couldn't deal with the nerdy taped-together look.
I also suggest *quality* glasses. All the really dark mirrored cheapies don't work very well even though they are dark. The unfortunate feature is that the Ray-Ban ambermatics were discontinued for years and I had to go to a vintage sunglass website to get spares, and you can assume it was not to be confused with a charity operation The other problem is that all the places you go for sunglasses treat them as fashion statements, not optical devices, and you can't get straight technical answers about transmissivity, etc.
Of course, the usual rules apply, don't ever look straight at the sun - not because of eye damage, but because it will briefly "zap" your eyes and you will lose sight of it for a few seconds.
