Since this topic is up, while anyone is answering stilly's question, could you comment on the following:

Is there a difference between the polarizing effect achieved with plastic lenses versus glass lenses? Can plastic achieve the same performance as glass. I have a bad perscription, which when corrected with glass lenses, supposedly results in glasses that are too heavy, or something. With Action Optics, I only had the option of plastic lenses with my perscription.

With my plastic lenses, the options for my colors were a sort of a brown (copper?), and a kind of gray. I chose the brown. They take the glare off the water, but the contrast leaves something to be desired. Is there a better color to achieve more contrast?

I really don't know what I should expect out of a good pair of polarized lenses. The ones I have are certainly better than nothing, but it seems that the performance could be better.

Any help you could give me would be much appreciated. Thanks, Tad.
