Ray I've been thru all the different types of sunglasses you can think of, polarized, blue block etc. As a matter of fact just this week I again compared Zurichs to 3 very expensive polarized glasses. I finally settled on Zurichs about 10 years ago. As far as I'm concerned they are the best sunglasses I have ever used flying. Since we are looking into the sky while flying I found that they provide the best definition and best protection for our activity. Others may disagree, which is fine as I know people who don't wear any sunglasses when they fly, but for my money Zurich is the only thing I'll wear flying. If you want function buy Zurichs. They won't get many 'style' points but style isn't their purpose.
