Recently, I tried buy non-polarized clip-on or flip-up sunglasses for my prescription glasses. There hundreds, but all were polarized. Does anyone know where non-polarized clip-ons or flip-ups can be found? Any reputable optometrist should be able to put non polarized lenses in your clipon glasses - when I bought my first pair of corrective glasses the clipons that came by default were polarized, i asked for them to be replaced with non polarized lenses, it added the benefit of choosing the tint I wanted. Additionally I would recommend getting corrective sunglasses instead of clipons for your regular glasses.. I found the clipons let in too much light between the tinted lens and the corrective lens. When buying dedicated prescription sunglasses you can choose non polarized lens. Cheers, Luke




So- I lose the polarization which I find is a big help in cloud reading, so that I can read a Flarm display.


Not the best trade off for this pilot.

I did not realize polarized glasses helped with cloud reading. During

training we were told not to purchase polarized glasses as it may

produce blind spots due to refraction issues/imperfect canopies etc...

Since then I've always been under the (apparently mistaken)impression

that most pilots flew with non-polarized glasses, and have avoided

purchasing anything with polarization. I'll have to give polarized

lenses a try see if they help! I much rather see clearly outside than

any instruments in the cockpit.



Cheers,

There are those who swear by polarized glasses (like myself) and those who don't. I only fly with polarized glasses as I find them improving visibility of clouds, haze domes AND other gliders significantly, as well as reducing canopy reflections. I suspect those who claim otherwise didn't give them a try. I definitely not intend to give up my polarized glasses so I can read the flarm display. The solution as I suggested earlier is to rotate the display or switch to the panel mount display. Perhaps putting more pressure on the butterfly folks to address this issue will help.
