chevv,
The Serengeti sunglasses to which I referred had a fix gradient tint( darker at the top of the lens, lightening toward the bottom) vs a degree of tint that changed in relation to ambient light levels.
I wore them for many years with no difficulty while looking through quite a few cockpit windshields. In fact, I was able to get my Rx lenses done by Serengeti in the same configuration. I don't think Corning Glass does Rx lenses any longer.
Horses for courses !
