<div>This is a very informative article and explains why the polarized sunglasses work so well with high glare (i.e., horizontal sun glare).

Here is a very good explanation.

Another thing about polarized lenses in my experience is that if you tilt your head while flying, you'll have issues with seeing your airplane. Whether flying models or real planes, I won't used polarized lenses. You'll also find that if your vehilce has tinted windows, you won't get the polarized effect because most tint also is polarized. They effectively cancel each other out. Polarized lenses are made to get rid of a lot of the horizontal reflected light such as a boater gets on the water or a driver gets from a wet surface of road.

… wish I didn't get them. Very difficult to read an LCD screen (transmitter, iPhone, etc). Not that great. Jim

Tried these over the last couple of months with the following results:

Excellent results when sun was low angle (e.g., in morning with sun in eyes or evening at other fields when sun is in eyes). The glasses provide better clarity and sharper image as well as better optical comfort, particularly in these conditions.

Poor results when sun is very high, just overhead, like around noon-ish. Plane is hard to see or takes more concentration to see at certain angles (like coming out of a radius after a stall turn with 1 1/4 snaps at the end of the box where I'm looking at mainly the leading edge under side of the wing).

For the "Doctors" in the audience (or opticians), why is this?

I'm thinking that the sun casts "shadows" between the polarized lines of the glasses. This is assuming that the polarized lines are horizontal (I'm pretty sure but not positive).

Bottom line, I like them for some conditions, but not all the time.

P.S. I can't read my Thunder Power charger or my Tx screen at certain angles. The screen goes black but when I'm looking straight down from above I can see the screen without it going black.
