When I first purchased this, I was not impressed. It did nothing. However, I read Aimpoint's instructions and it states that the filter can be rotated 180* to provide varying effect. I did not see how this was possible, given that the filter is a plastic lens embedded in a rubber insert that is pressed into the ocular of the Comp series Aimpoint. Rotating the lens meant just rotating the rubber housing in the ocular. Anyway, today I tried it, and...WOW!

Yup, that's how a polarizer works. You have to adjust it based on the angle of the incoming light. You can see this with polarized glasses, as well, when looking at LCD screens (since the light is constant) as you rotate the lens.

Yep. I used to be in the optical field. Very funky how polarizing works. If you put two lenses in your glasses and the polarization axises weren't completely horizontal (or close to horizontal) across both lenses, it would screw you all up.

Where did you pick yours up? Everywhere I've been looking says they're discontinued. Argh.

Interesting idea putting the filter directly on the optic, looks like it for sure cuts down on glare. All of my sun/shooting glasses are polarized and I use polarizing filters on my cameras from time to time.
