That happens on my Prizm Field too (non-polarized), as well as Deep Water Prizm (polarized) and I was checking out sunglasses at Bass Pro Shop last week and it was happening with the Prizm Maritime as well as with some Maui Jims I was looking at. Funny I never noticed it with cheap sunglasses. Sometimes I even notice it when driving looking at the brake lights.
I even have it happen on my photochromatic Oakley's when they are clear - very frustrating, really the only two things I don't like about my Oakley's - that ghosting and the price.
You were right.
Checked today, mostly they do. In some lens colors more noticeable than others.
But In prizm non-polarized I didn't see it.
I still like them. Prizm Tungsten may be my next pair. Cloudy and sadly days look nicer
