Windshield distortion

[pleeson]

Anyone ever seen a windshield that is distorted, opaque in places, and obscured in others by rainbow colors and refraction when wearing polarized sunglasses on a bright day? No problem other than a slight hazy look without the glasses but it looks to me that there is a flaw in the lamination process...

You are going to see distortion when you look through the laminated windshield with polarized glasses. You'll notice the distortion changes if you rotate glasses 90 degrees. Sometimes if windshield gets heated up it will be more pronounced. Nothing wrong with windshield; it's the nature of polarized glasses. For this reason I'm not allowed to wear polarized glasses when I fly.

Interesting point of view - I am a helicopter pilot so have not noticed this with our "plexiglass" windshields, nor have I ever seen a problem with a car windshield. Why should a boat windshield be any different?

M/B because the helicoper windshield isn't laminated. My experience with polarized lenses, cameras and eyeglasses, reveals it's always an issue with some surfaces, including water on the roadway. MFD screens are a big problem.

Have to remove my polarized sunglasses to see the screen of my backup camera. :shock:

I gave up on polarized glasses years ago with the proliferation of LCD screens on just about everything. Got tired of having to tilt my head to see the radio controls.

I do recall noting that laminated automotive glass would sometimes look goofy.

Army H34s had Polarizing window screens for practicing instrument flying. Put on your polarized sun glasses and the outside disappeared forcing trainee/testee to focus on instruments.
