Given the 'thread drift' apparent here, one would think the whole polarised lens issue with regards aviation was a recent thing related solely to glass cockpits... NOT SO.

As a student back in the late 70's (when polarised lenses were all the rage -waaaaay before the advent of a glass cockpit) we were advised not to accept a polarised lens for aviation use!!!

They CAN and DO create an optical illusion late in the flare (when your eye is looking more towards the bottom of the lens) that is at the very least disconcerting! I don't intend to detract from the fact of the problems asscociated with a polarised lens and a glass cockpit, but to be clear, stress there is more to it than just that.

Simply, polarised lenses and aviation are not a good mix.
