This is an interesting reply I received when I posted the same question on the Bass Boat Central Forum.

[#0000ff][size 2]The LCD displays have a somewhat polarized effect, but not horizontally like sunglasses are.
Sunglasses are made to lessen horizontal glare.
Humminbird displays have the "polarization" on a 45 degree slant from top right to lower left.
When wearing sunglasses and you tilt your head to the right, it basically shuts off the light transmission.
You typically do that when the display is to the right.
Lowrance screens have the same slant. Garmin is opposite.
Hold you glasses in front of the display and tilt them left and right to see the effect. The screen will be brighter with the glasses tilted left (polarization is the same), somewhat dim when level, and blacked out tilted right (polarization is 90 degrees of each other).
To lessen the effect, you can position the display with the right side lower than the left and you probably won't tilt your head enough to block out all the light.[/size][/#0000ff]
